FOLIO Update November 2019

Here at Duke, the buzz continues around FOLIO. We have continued to contribute to the international project  as active participants on the FOLIO Product Council,  special interest groups, and contribute development resources. You can find links to the various groups on the FOLIO wiki.

We’ve also committed to implementing the electronic resource management (ERM)-focused apps in summer of 2020. Starting with the ERM-focused apps will give us the opportunity to use FOLIO in a production environment, and will be a benefit to our Continuing Resource Acquisitions Department since they are not currently using software dedicated to electronic resources to keep track of licences and terms.

 

Our local project planning has come more into focus as well. We have gathered names for team participants and will be kicking off our project teams in January. As we’ve talked about the implementation here, we’ve realized that we have a number of tasks that will need to be addressed, regardless of subject matter. For example, we’re going to need to map data – not just bibliographic, holdings and item data, but users, orders, invoices, etc. We’ll also need to set up configurations and user permissions for each of the apps, and document, train, and develop new workflows. Since our work is not siloed in functional areas, we need to facilitate discussions among the functional areas. To do that, we’re going to create a set of functional area implementation teams, and work groups around the task areas that need to be addressed.

Celebrating a New Duke Digital Collections Milestone with Section A

Duke Digital Collections recently passed 100,000 items!

 

Last week, it was brought to our attention that Duke Digital Collections recently passed 100,000 individual items found in the Duke Digital Repository! To celebrate, I want to highlight some of the most recent materials digitized and uploaded from our Section A project. In the past, Bitstreams has blogged about what Section A is and what it means, but it’s been a couple of years since that post, and a little refresher couldn’t hurt.

What is Section A?

In 2016, the staff of Rubenstein Research Services proposed a mass digitization project of Section A. This is the umbrella term for 175 boxes of different historic materials that users often request – manuscripts, correspondence, receipts, diaries, drawings, and more. These boxes contain around 3,900 small collections that all had their own workflows. Every box needs consultations from Rubenstein Research Services, review by Library Conservation Department staff, review by Technical Services, metadata updates, and more, all to make sure that the collections could be launched and hosted within the Duke Digital Repository. 

In the 2 years since that blog post, so much has happened! The first 2 Section A collections had gone live as a sort of proof-of-concept, and as a way to define what the digitization project would be and what it would look like. We’ve added over 500 more collections from Section A since then. This somehow barely even scratches the surface of the entire project! We’re digitizing the collections in alphabetical order, and even after all the collections that have gone online, we are currently still only on the letter “C”! 

Nonetheless, there is already plenty of materials to check out and enjoy. I was a student of history in college, so in this blog post, I want to particularly highlight some of the historic materials from the latter half of the 19th century.

Showing off some of Section A

Clara Barton’s description of the Grand Hotel de la Paix in Lyon, France.

In 1869, after her work as a nurse in the Civil War, Clara Barton traveled around Europe to Geneva, Switzerland and Corsica, France. Included in the Duke Digital Collections is her diary and calling cards from her time there. These pages detail where she visited and stayed throughout the year. She also wrote about her views on the different European countries, how Americans and Europeans compare, and more. Despite her storied career and her many travels that year, Miss Barton felt that “I have accomplished very little in a year”, and hoped that in 1870, she “may be accounted worthy once more to take my place among the workers of the world, either in my own country or in some other”.

Back in America, around 1900, the Rev. John Malachi Bowden began dictating and documenting his experiences as a Confederate soldier during the Civil War, one of many that a nurse like Miss Barton may have treated. Although Bowden says he was not necessarily a secessionist at the beginning of the Civil War, he joined the 2nd Georgia Regiment in August 1861 after Georgia had seceded. During his time in the regiment, he fought in the Battles of Fredericksburg, Gettysburg, Spotsylvania Court House, and more. In 1864, Union forced captured and held Bowden as a prisoner at Maryland’s Point Lookout Prison, where he describes in great detail what life was like as a POW before his eventual release. He writes that he was “so indignant at being in a Federal prison” that he refused to cut his hair. His hair eventually grew to be shoulder-length, “somewhat like Buffalo Bill’s.”

Speaking of whom, Duke Digital Collections also has some material from Buffalo Bill (William Frederick Cody), courtesy of the Section A initiative. A showman and entertainer who performed in cowboy shows throughout the latter half of the 19th century, Buffalo Bill was enormously popular wherever he went. In this collection, he writes to a Brother Miner about how he invited seventy-five of his “old Brothers” from Bedford, VA to visit him in Roanoke. There is also a brief itinerary of future shows throughout North Carolina and South Carolina. This includes a stop here in Durham, NC a few weeks after Bill wrote this letter.

Buffalo Bill’s letter to his “Brother Miner”, dated October 17, 1916.

Around this time, Walter Clark, associate justice of the North Carolina Supreme Court, began writing his own histories of North Carolina throughout the 18th and 19th centuries. Three of Clark’s articles prepared for the University Magazine of the University of North Carolina have been digitized as part of Section A. This includes an article entitled “North Carolina in War”, where he made note of the Generals from North Carolina engaged in every war up to that point. It’s possible that John Malachi Bowden was once on the battlefield alongside some of these generals mentioned in Clark’s writings. This type of synergy in our collection is what makes Section A so exciting to dive into.

As the new Still Image Digitization Specialist at the Duke Digital Production Center, seeing projects like this take off in such a spectacular way is near and dear to my heart. Even just the four collections I’ve highlighted here have been so informative. We still have so many more Section A boxes to digitize and host online. It’s so exciting to think of what we might find and what we’ll digitize for all the world to see. Our work never stops, so remember to stay updated on Duke Digital Collections to see some of these newly digitized collections as they become available. 

Data Sciencing our Journal Subscriptions

The ongoing tensions between academic institutions and publishers have been escalating the last few months, but those tensions have existed for many years. The term “Big Deal” has been coined to describe a long-standing, industry-wide practice of journal bundling that forces libraries to subscribe to unwanted and unneeded publications rather than paying more for a limited number of individual subscriptions. This is a practice you see in other industries – for example, cable packages that provide hundreds of channels, even if you only want one or two specific channels.

What is especially problematic in higher education is that academics produce and review the content that gets published in the journals (for free), and then the universities have to pay the publishers a subscription fee to access the content. Imagine if YouTube required a subscription fee to watch any videos, including the ones you had posted. It’s a system that makes research harder to access and inhibits global scientific progress, all so publishers can earn an enormous profit margin.

Right now, academic publishing is controlled by five publishers (the “Big Five”) – a monopoly that makes it very difficult for libraries to negotiate better deals. Only very large organizations or consortia, like the University of California, have been able to start pushing back against the system. It will likely take large shake-ups like this for any large changes to take hold, but it in the meantime there may be ways to situate ourselves for making better purchasing decisions.

At Duke, we often review our usage of specific journal titles as we prepare to make purchasing decisions. Usage data comes in a variety of forms, but the most popular are counts of Duke views and downloads that come directly from the publishers and the number of times Duke authors publish in or cite a particular journal. There are many other kinds of data that might be of interest, however, including Duke participation on editorial boards, usage differences across disciplines, and even whether or not the journal is fully open access. Blending various data sources and optimizing the search decisions for a given budget cycle can be overwhelming.

Last fall, Duke University Libraries decided to propose a project for Duke’s Data+ summer program – a summer research experience in data science for undergraduate students. Our project, “Breaking the Bundle: Analyzing Duke’s Journal Subscriptions“, focuses on Duke’s subscriptions to journals published by Elsevier. The program is in its third week, and our team of two incredibly-sharp undergraduates has been hard at work building and blending our datasets. Our goal by the end of summer is to have a proof-of-concept dashboard that lets collection managers adjust the weights of various usage measures to generate an ideal collection of journals for a particular budget.

It is still very early in the process, but the students have been hard at work and have made great progress. We decided it would be best to develop the analysis software and dashboard using R, a statistical computing project with a rich history and many helpful development tools. In addition to publisher-provided views and downloads, the students have been able to use websites and APIs to collect data on journal open access status, editorial boards, numbers of publications, and numbers of citations. All Data+ teams present publicly on the projects twice during the summer, and we hope to schedule a third talk for a library audience before the end of the program on August 2.

Sample R code from the project
Just one of many files of R code generated for the project so far.

We look forward to seeing what the summer will bring! While this project is just one small step, automating the collection and analysis of journal usage will position us well, both for responsible purchases and for a hopefully-changing publishing landscape.

New Duke Libraries catalog to go live January 16

The wait is almost over!  After over two years of hard work by library staff at Duke, NCCU, NCSU, and UNC, we’ll be launching a new catalog for researchers to use to locate and access books, DVDs, music, archival materials, and other items held here at Duke and across the other Triangle Research Libraries member libraries (NCSU, NCCU, UNC).  The new collaboratively developed, open-source library catalog will replace the decade-old Duke Libraries catalog and Search TRLN catalog.    

What to expect from the new catalog

While the basic functionality of the catalog remains the same – researchers will be able to search across the 15 million+ items at Duke and area libraries – we think you’ll enjoy some nice enhancements and updates to the catalog:  

  • a more modern search interface
  • prominent filters to modify search results, including an option to narrow your search to items available online
  • a more intuitive button to expand search results to include items held at UNC, NCCU, and NCSU
  • updated item pages with easier access to request and export materials
  • improved access to an item’s availability status and its location  
  • more user-friendly options to email, text, or export citation information
  • improved display of multi-part items (click “View Online” to access individual episodes)
  • more robust Advanced Search with options to search by Publisher and Resource type (e.g., book, video, archival material)
Screenshot of full item page.
Item pages have been updated and include a sidebar with easy access to Request and Email/Text options.

You might notice some differences in the way the new catalog works.  Learn more with this handy new vs. old catalog comparison chart.  (Note that we plan to implement some of the features that are not currently available in the new catalog this spring – stay tuned for more info, and let us know if there are aspects of the old catalog that you miss.)  And if you run into trouble or have more questions about using the new catalog, check out these library catalog search tips, or contact a librarian for assistance.

We welcome your feedback

While the new catalog is fully functional and boasts a number of enhancements, we know there is still work to be done, and we welcome your input.  We invite you to explore the new catalog at https://find.library.duke.edu/ and report problems or provide general feedback through this online form.  We’ll continue to conduct user testing this spring and make improvements based on what we learn – look for the “Free Coffee” sign in the Perkins Library lobby, and stop by to tell us what you think.

Digital Collections Round Up 2018

It’s that item of year where we like to reflect on all we have done in 2018, and your favorite digital collections and curation services team is no exception.  This year, Digital Collections and Curation Services have been really focusing on getting collections and data into the Digital Repository and making it accessible to the world!

As you will see from the list below we launched 320 new digital collections, managed substantial additions to 2, and migrated 8. However, these publicly accessible digital collections are just the tip of the iceberg in terms of our work in Digital Collections and Curation Services.

A cover from the Ladyslipper, Inc Retail Catalogs digital collection.

So much more digitization happens behind the scenes than is reflected in the list of new digital collections.  Many of our larger projects are years in the making. For example, we continue to digitize Gedney photographs and we hope to make them publicly accessible next year.  There is also preservation digitization happening that we cannot make publicly accessible online.  This work is essential to our preservation mission, though we cannot share the collections widely in the short term.

We strongly believe in keeping our metadata healthy, so in addition to managing new metadata, we often revisit existing metadata across our repositories in order to ensure its overall quality and functionality.

Our team is also responsible for ingesting not just digital collections, but research data and library collections as well.  We preserved 20 datasets produced by the Duke Scholarly Community in the Research Data Repository (https://research.repository.duke.edu/)  via the Research Data Curation program https://library.duke.edu/data/data-management.

Collections Migrated into the Digital Repository

A collaborative approach to developing a new Duke Libraries catalog

Post contributed by: Emily Daly, Thomas Crichlow, and Cory Lown

If you’re a frequent or even casual user of the Duke Libraries catalog, you’ve probably noticed that it’s remained remarkably consistent over the last decade. Consistency can be a good thing, but there is certainly room for improvement in the Duke Libraries catalog, and staff from the libraries at Duke, UNC, and NCSU are excited to replace the current catalog’s aging infrastructure and outdated user interface with an entirely new collaboratively developed open-source discovery layer. While many things are changing, one key feature will remain the same: The catalog will continue to allow users to locate and access materials not only here at Duke but also across the other Triangle Research Libraries member libraries (NCSU, NCCU, UNC).

Users will be able to search for items in the Duke Libraries catalog and then expand to see books and items from NCSU, NCCU, and UNC if they wish.

Commitment to collaboration

In addition to an entirely new central index that supports institutional and consortial searching, the new catalog benefits from a shared, centrally developed codebase as well as locally hosted, customizable catalog interfaces. Perhaps most notably, the new catalog has been built with the needs of library and complex bibliographic data in mind. While the software used for the current library catalog has evolved and grown in complexity to support e-commerce and business needs (not higher ed or library needs), the library software development community has been hard at work building specialized discovery layers using the open-source Blacklight framework. Peer institutions including Stanford, Cornell, and Princeton are already using Blacklight for their library catalogs, and there is an active Blacklight development community that Duke is excited to be a part of. Being part of this community enables us to build on the good work already in place in other library catalogs, including more intuitive facets, adaptive linking for subjects and other fields, a more responsive user interface for access via tablets and phones, and the ability to preserve the order of MARC fields when it’s useful to researchers (MARC is an international standard for representing bibliographic and related data).

We’re upping our collaboration game locally, too: This project has given us the opportunity to develop a new model for collaborative software development. Rather than reinvent the wheel at each Triangle Research Library, we’re combining effort and expertise to develop a feature-rich yet highly customizable discovery layer that will serve the needs of researchers across the triangle. To do this, we have adopted an agile project management process with talented developers and dedicated product owners from NCSU, UNC, and Duke. The agile approach has helped us be more productive and efficient during the development phase and increased collaboration across the four Triangle Research Libraries, positioning us well for maintaining and governing the catalog after we go live.

This image depicts the structure of the development team that was formed in May 2017 to collaboratively build the new library catalog.

What’s next?

The development team has already conducted multiple rounds of user testing and made changes to the user interface based on findings. We’re now ready to hear feedback from library staff. To facilitate this, we’ll be launching the Duke instance of the catalog to all library staff next Wednesday, August 1. We encourage staff to explore catalog features and records and then report feedback, providing screenshots, URLs, and other details as needed. We’ll continue user testing this fall and solicit extensive feedback from faculty, students, staff, and general researchers.

Our plan (fingers crossed!) is to officially launch the new Duke Libraries catalog to all users in early 2019, perhaps as soon as the start of the spring semester. A local implementation team is already at work to be sure we’re ready to replace Duke’s old catalog with the new and improved version early next year. Meanwhile, development and interface enhancement of the catalog will continue this fall. While we are pleased with what we’ve accomplished over the last 18 months, there is still significant work to be done before we’ll be ready to go live. Here are a few items on the lengthy TO DO list:

  • finish loading the 16 million records from all four Triangle Research libraries
  • integrate Duke’s request workflows so users can request items they discover in the new catalog
  • develop a robust Advanced Search interface in response to user demand
  • tune relevance ranking
  • ensure that non-Roman scripts are searchable and display correctly
  • map non-MARC metadata so items such as digital collections records are discoverable
Effective search and display of non-Roman scripts is just one of the many items left on our list before we launch the library catalog to the public.

There is a lot of work ahead to be sure, but what we will launch to staff next week is a functional catalog with nearly 10 million records, and that number is increasing by the day. We invite you to take the new catalog for a spin and tell us what you think so we can make improvements and be ready for all researchers in just a few short months.

Charm City Sounds

Last week I had the opportunity to attend the 52nd Association for Recorded Sound Collections Annual Conference in Baltimore, MD.  From the ARSC website:

Founded in 1966, the Association for Recorded Sound Collections, Inc. is a nonprofit organization dedicated to the preservation and study of sound recordings—in all genres of music and speech, in all formats, and from all periods.

ARSC is unique in bringing together private individuals and institutional professionals. Archivists, librarians, and curators representing many of the world’s leading audiovisual repositories participate in ARSC alongside record collectors, record dealers, researchers, historians, discographers, musicians, engineers, producers, reviewers, and broadcasters.

ARSC’s vitality springs from more than 1000 knowledgeable, passionate, helpful members who really care about sound recordings.

ARSC Annual Conferences encourage open sharing of knowledge through informative presentations, workshops, and panel discussions. Tours, receptions, and special local events heighten the camaraderie that makes ARSC conferences lively and enjoyable.

This quote highlights several of the things that have made ARSC resources valuable and educational to me as the Audio Production Specialist at Duke Libraries:

  • The group’s membership includes both professionals and enthusiasts from a variety of backgrounds and types of institutions.
  • Members’ interests and specialties span a broad array of musical genres, media types, and time periods.
  • The organization serves as a repository of knowledge on obscure and obsolete sound recording media and technology.

This year’s conference offered a number of presentations that were directly relevant to our work here in Digital Collections and Curation Services, highlighting audio collections that have been digitized and the challenges encountered along the way.  Here’s a quick recap of some that stood out to me:

  • “Uncovering the Indian Neck Folk Festival Collection” by Maya Lerman (Folklife Center, Library of Congress).  This presentation showcased a collection of recordings and related documentation from a small invitation-only folk festival that ran from 1961-2014 and included early performances from Reverend Gary Davis, Dave Van Ronk, and Bob Dylan.  It touched on some of the difficulties in archiving optical and born-digital media (lack of metadata, deterioration of CD-Rs) as well as the benefits of educating prospective donors on best practices for media and documentation.
  • “A Garage in South Philly: The Vernacular Music Research Archive of Thornton Hagert” by David Sager and Anne Stanfield-Hagert.  This presentation paid tribute to the massive jazz archive of the late Mr. Hagert, comprising over 125,000 items of printed music, 75,000 recordings, 5,500 books, and 2,000 periodicals.  It spoke to the difficulties of selling or donating a private collection of this magnitude without splitting it up and undoing the careful, but idiosyncratic organizational structure as envisioned by the collector.
  • “Freedom is a Constant Struggle: The Golden State Mutual Sound Recordings” by Kelly Besser, Yasmin Dessem and Shanni Miller (UCLA Library).  This presentation covered the audio material from the archive of an African American-owned insurance company founded in 1925 in the Bay Area.  While audio was only a small part of this larger collection, the speakers demonstrated how it added additional context and depth to photographs, video, and written documents.  They also showed how this kind of archival audio can be an important tool in telling the stories of previously suppressed or unheard voices.
  • “Sounds, Sights and Sites of Activism in ’68” by Guha Shankar (Library of Congress).  This presentation examined a collection of recordings from “Resurrection City” in Washington, DC.  This was an encampment that was part of the Poor People’s Campaign, a demonstration for human rights organized by Martin Luther King, Jr. prior to his assassination in 1968.  The talk showed how these archival documents are being accessed and used to inform new forms of social and political activism and wider circulation via podcasts, websites, public lecture and exhibitions.

The ARSC Conference also touched on my personal interests in American traditional and vernacular music, especially folk and blues from the early 20th Century.  Presentations on the bluegrass scene in Baltimore, blues guitarist Johnny Shines, education outreach by the creators of PBS’s “American Epic” documentaries, and Hickory, NC’s own Blue Sky Boys provided a welcome break from favorite archivist topics such as metadata, workflows, and quality control.  Other fun parts of the conference included an impromptu jam session, a silent auction of books & records, and posters documenting the musical history of Baltimore.  True to the city’s nickname, I was charmed by my time in Baltimore and inspired by the amazingly diverse and dedicated work towards collecting and preserving our audio heritage by the ARSC community.

 

 

Living Our Best DSpace Lives

Last week, an indefatigable team at Duke University Libraries released an upgraded version of the DukeSpace platform, completing  the first phase of the critical project that I wrote about in this space in January.  One member of the team remarked that we now surely have “one of the best DSpaces in the world,” and I dare anyone to prove otherwise.

DukeSpace serves as the Libraries’ open-access institutional repository, which makes it a key aspect of our mission to “partner in research,” as outlined in our strategic plan.  As I wrote in January, the version of the DSpace platform that underlies the service had been stuck at 1.7, which was released during 2010 – the year the iPad came out, and Lady Gaga wore a meat dress. We upgraded to version 6.2, though the differences between the two versions are so great that it would be more accurate to call the project a migration.

That migration turned out to be one of the more complex technology projects we’ve undertaken over the years. The main complicating factor was the integration with Symplectic Elements, the Research Information Management System (RIMS) that powers the Scholars at Duke site. As far as we know, we are the first institution to integrate Elements with DSpace 6.2. It was a beast to do, and we are happy to share our knowledge gained if it will help any of our peers out there trying to do the same thing.

Meanwhile, feel free to click on over to and enjoy one of the best DSpaces in the world. And congratulations to one of the mightiest teams assembled since Spain won the World Cup!

Interactive Transcripts have Arrived!

Interactive Transcripts have Arrived!

This week Duke Digital Collections added our first set of interactive transcripts to one of our newest digital collections: the Silent Vigil (1968) and Allen Building Takeover (1969) collection of audio recordings.   This marks an exciting milestone in the accessibility efforts Duke University Libraries has been engaged in for the past 2.5 years. Last October, my colleague Sean wrote about our new accessibility features and the technology powering them, and today I’m going to tell you a little more about why we started these efforts as well as share some examples.

Interactive Transcript in the Silent Vigil (1968) and Allen Building Takeover (1969) Audio Recordings

Providing access to captions and transcripts is not new for digital collections.  We have been able to provide access to pdf transcripts and caption both in digital collections and finding aids for years. See items from the Behind the Veil and Memory Project digital collections for examples.

In recent years however, we stepped our efforts in creating captions and transcripts. Our work began in response to a 2015 lawsuit brought against Harvard and MIT by the National Association of the Deaf. The lawsuit triggered many discussions in the library, and the Advisory Council for Digital Collections eventually decided that we would proactively create captions or transcripts for all new A/V digital collections assuming it is feasible and reasonable to do so.  The feasible and reasonable part of our policy is key.  The Radio Haiti collection for example is composed of thousands of recordings primarily in Haitian Creole and French.  The costs to transcribe that volume of material in non-English languages make it unreasonable (and not feasible) to transcribe. In addition to our work in the library, Duke has established campus wide web accessibility guidelines that includes captioning and  transcription.  Therefore our work in digital collections is only one aspect of campus wide accessibility efforts.

To create transcripts and captions, we have partnered with several vendors since 2015, and we have seen the costs for these services drop dramatically.  Our primary vendor right now is Rev, who also works with Duke’s Academic Media Services department.  Rev guarantees 99% accurate captions or transcripts for $1/minute.

Early on, Duke Digital Collections decided to center our captioning efforts around the WebVTT format, which is a time-coded text based file and a W3C standard.  We use it for both audio and video captions when possible, but we can also accommodate legacy transcript formats like pdfs.  Transcripts and captions can be easily replaced with new versions if and when edits need to be made.

Examples from the Silent Vigil (1968) and Allen Building Takeover (1969) Audio Recordings

When WebVTT captions are present, they load in the interface as an interactive transcript.  This transcript can be used for navigation purposes; click the text and the file moves to that portion of the recording.

Click the image above to see the full item and transcript.

In addition to providing access to transcripts on the screen, we offer downloadable versions of the WebVTT transcript as a text file, a pdf or in the original webVTT format.

An advantage of the WebVTT format is that it includes “v” tags, which can be used to note changes in speakers and one can even add names to the transcript.  This can require additional  manual work if the names of the speakers is not obvious to the vendor, but we are excited to have this opportunity.

As Sean described in his blog post, we can also provide access to legacy pdf documents.  They cannot be rendered into an interactive version, but they are still accessible for download.

On a related note, we also have a new feature that links time codes listed in the description metadata field of an item to the corresponding portion of the audio or video file.  This enables librarians to describe specific segments of audio and/or video items.  The Radio Haiti digital collection is the first to utilize this feature, but the feature will be a huge benefit to the H. Lee Waters and Chapel Recordings digital collections as well as many others.

Click the image above to interact with linked time codes.

As mentioned at the top of this post, the Duke Vigil and Allen Building Takeover collection includes our first batch of interactive transcripts.  We plan to launch more this Spring, so stay tuned!!

Moving the mountain (of data)

It’s a new year! And a new year means new priorities. One of the many projects DUL staff have on deck for the Duke Digital Repository in the coming calendar year is an upgrade to DSpace, the software application we use to manage and maintain our collections of scholarly publications and electronic theses and dissertations. As part of that upgrade, the existing DSpace content will need to be migrated to the new software. Until very recently, that existing content has included a few research datasets deposited by Duke community members. But with the advent of our new research data curation program, research datasets have been published in the Fedora 3 part of the repository. Naturally, we wanted all of our research data content to be found in one place, so that meant migrating the few existing outliers. And given the ongoing upgrade project, we wanted to be sure to have it done and out of the way before the rest of the DSpace content needed to be moved.

The Integrated Precipitation and Hydrology Experiment

Most of the datasets that required moving were relatively small–a handful of files, all of manageable size (under a gigabyte) that could be exported using DSpace’s web interface. However, a limited series of data associated with a project called The Integrated Precipitation and Hydrology Experiment (IPHEx) posed a notable exception. There’s a lot of data associated with the IPHEx project (recorded daily for 7 years, along with some supplementary data files, and iterated over 3 different areas of coverage, the total footprint came to just under a terabyte, spread over more than 7,000 files), so this project needed some advance planning.

First, the size of the project meant that the data were too large to export through the DSpace web client, so we needed the developers to wrangle a behind the scenes dump of what was in DSpace to a local file system. Once we had everything we needed to work with (which included some previously unpublished updates to the data we received last year from the researchers), we had to make some decisions on how to model it. The data model used in DSpace was a bit limiting, which resulted in the data being made available as a long list of files for each part of the project. In moving the data to our Fedora repository, we gained a little more flexibility with how we could arrange the files. We determined that we wanted to deviate slightly from the arrangement in DSpace, grouping the files by month and year.

This meant we would have group all the files into subdirectories containing the data for each month–for over 7,000 files, that would have been extremely tedious to do by hand, so we wrote a script to do the sorting for us. That completed, we were able to carry out the ingest process as normal. The final wrinkle associated with the IPHEx project was making sure that the persistent identifiers each part of the project data had been assigned in DSpace still resolved to the correct content. One of our developers was able to set up a server redirect to ensure that each URL would still take a user to the right place. As of the new year, the IPHEx project data (along with our other migrated DSpace datasets) are available in their new home!

At least (of course) until the next migration.
