We are very excited to see the initial release of the Move to Islandora Kit tool (v0.9.0). Our very own developer Marcus Barnes along with Mark Jordan from Simon Fraser University are the current maintainers for this module.

The Move to Islandora Kit is an extensible PHP command-line tool for converting source content and metadata into packages suitable for importing into Islandora (or other digital repository and preservations systems). We find it to be a very powerful, extensible tool with a lot of potential applications and uses for migrations across many different systems.

We’re in full on Islandora testing mode in preparation for the upcoming 7.x - 1.9 release and the release of our Web Annotation Utility Module and our Oral History Solution Pack prior to IslandoraCon.

As part of our testing, we found we needed the ability to have multiple users simultaneously accessing the same VM. Our systems administrator showed us a neat trick for those of you using Islandora VMs for testing and development. So, here it is:

Irfan's cool trick for letting others into your VM:

  1. With your Virtual Machine off, go to settings/network. There are slots for 4 adapters. By default the drop-down is set to "Nat." Change this to "Bridged Adapter" and start machine. 
  2. Login to the machine using the interface provided by the VM and find your IP address by running ifconfig -a | grep inet
  3. Provide this address to others. The IP + :8000 is Drupal for the VM provided by the Islandora release team (for example, 142.1.101.136:8080)

Note the following:

  • You now login (ssh) at vagrant@IPaddress (like vagrant@142.1.101.136)
  • Your IP might change, and you may to have to find the address again 
  • Your network may change, causing you to have to run sudo /etc/init.d/networking and restart to update the machine's IP address
  • This may have some unintended affects when performing Drupal functions

Overall, YMMV, but this has been very useful to us when testing.

Our own Kim Pham has returned from Code4Lib 2017 in Los Angeles, where she presented a unit poster describing our work on the Web Annotation Framework (a solution pack with a release coming soon!). You can view the Poster in Tspace.

 

Thursday, March 16, 2017 - 12:38

We're happy to announce that a new publication by the unit, titled Supporting Oral Histories in Islandora is available in the January issue of Code4Lib

"Since 2014, the University of Toronto Scarborough Library’s Digital Scholarship Unit (DSU) has been working on an Islandora-based solution for creating and stewarding oral histories (the Oral Histories solution pack). Although regular updates regarding the status of this work have been presented at Open Repositories conferences, this is the first article to describe the goals and features associated with this codebase, as well as the roadmap for development. An Islandora-based approach is appropriate for addressing the challenges of Oral History, an interdisciplinary methodology with complex notions of authorship and audience that both brings a corresponding complexity of use cases and roots Oral Histories projects in the ever-emergent technical and preservation challenges associated with multimedia and born digital assets. By leveraging Islandora, those embarking on Oral Histories projects benefit from existing community-supported code. By writing and maintaining the Oral Histories solution pack, the library seeks to build on common ground for those supporting Oral Histories projects and encourage a sustainable solution and feature set."

Check us out in issue 35: online and open source! If you're interested in the module, check out the code on Github.

Make Metadata Discoverable via the OAI-PMH in WorldCat

For the past few months, I was working as a practicum student at the University of Toronto Scarborough Library trying to figure out how to utilize the OAI module to help the Digital Scholarship Unit (DSU) make their metadata discoverable via the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) in WorldCat. Based on what I learned from the course INF2186 Metadata Schemas & Apps at UofT, I already had some basic knowledge of how to share metadata with a local, state, or regional digital metadata repository, and expose current metadata for OAI harvesting. This tutorial will teach you how I did this step by step.

Let’s start with some basic terms.

Step 0 - Terms to Get Started

Open Archive Initiative (OAI) is an initiative to develop and promote interoperability standards that aim to facilitate the efficient dissemination of content.

OAI Protocol for Metadata Harvesting (OAI-PMH) is a lightweight harvesting protocol for sharing metadata between services. In the OAI context, harvesting refers specifically to the gathering together of metadata from a number of distributed repositories into a combined data store.

There are two classes of participants in the OAI-PMH framework:

  • Data Providers administer systems that support the OAI-PMH as a means of exposing metadata; and
  • Service Providers use metadata harvested via the OAI-PMH as a basis for building value-added services.

Data Providers (open archives, repositories) provide free access to metadata, and may, but do not necessarily, offer free access to full texts or other resources. OAI-PMH provides an easy to implement, low barrier solution for Data Providers.

Service Providers use the OAI interfaces of the Data Providers to harvest and store metadata. Note that this means that there are no live search requests to the Data Providers; rather, services are based on the harvested data via OAI-PMH. Service Providers may select certain subsets from Data Providers (e.g., by set hierarchy or date stamp). Service Providers offer (value-added) services on the basis of the metadata harvested, and they may enrich the harvested metadata in order to do so.

Basic functioning of OAI-PMH

  • The OAI-PMH protocol is based on HTTP.
  • Responses are encoded in XML syntax. OAI-PMH supports any metadata format encoded in XML. Dublin Core is the minimal format specified for basic interoperability.

 

The diagram below is the overview and structure model of OAI-PMH.

Step 1 - Set Up Your OAI Module

The DSU currently use Islandora, an open-source, OAIS-based digital preservation repository and asset management system built on Drupal. First of all, going to the DSU home page, select Islandora ←  Islandora Utility Modules ← Islandora OAI from the navigation bar.

Then, the OAI module allows you to configure your URL path to the Repository. In this example, the base URL is http://dsu-beta.utsc.utoronto.ca/projects/oai2. If you want to see more records on your base URL, input the number you want to see under the “Maximum Response Size”. The default number here is 20 records per response.

Click on the Configure button below, you will find more setting configurations based on OAI request handler.

In OAI request handler, select the dc.identifier.thumbnail. If selected, a URL to the object's thumbnail will be added as a dc:identifier.thumbnail if the object has a thumbnail.

The DSU currently use MODS for all generic content going forwards - in past DSU used Dublin Core, but Islandora natively prefers MODS and it's more flexible for complex objects. For all fields that you want to display in WorldCat, you have to configure the metadata fields so that they are mapped to Dublin Core. Thus, I choose to transform MODS to Dublin Core.

Services like WorldCat expect links back to the object such as a Handle URL. If your metadata doesn't have this, self transforming XSLTs can be used to add specific elements tailored to individual needs.

Make sure you save all the settings in the end by clicking the Save Configuration button.

Step 2 - Test Your Base URL

OAI-PMH supports six request types (known as "verbs"). You can use them by simply adding these verbs after the base URL.

URLs for GET requests have keyword arguments appended to the base URL, separated from it by a question mark [?]. For example, the URL of a GetRecord request to DSU base URL that is http://dsu-beta.utsc.utoronto.ca/projects/oai2 could be:

http://dsu-beta.utsc.utoronto.ca/projects/oai2?

verb=GetRecord&identifier=oai:dsu-beta.utsc.utoronto.ca:utsc:519&metadataPrefix=oai_dc

Here is an explanation of all six request types:

  • GetRecords: This verb is used to retrieve an individual metadata record from a repository.
  • Identify: to retrieve information about a repository.
  • ListIdentifiers: retrieving only headers rather than records.
  • ListMetadataFormats: retrieve the metadata formats available from a repository.
  • ListRecords: used to harvest records from a repository.
  • ListSets: used to retrieve the set structure of a repository.

After you have exposed content types and some fields, your repository is available at /oai2

Some example requests are as follows:

http://dsu-beta.utsc.utoronto.ca/projects/oai2?verb=Identify

http://dsu-beta.utsc.utoronto.ca/projects/oai2?verb=ListMetadataFormats

http://dsu-beta.utsc.utoronto.ca/projects/oai2?verb=ListIdentifiers&metadataPrefix=oai_dc

http://dsu-beta.utsc.utoronto.ca/projects/oai2?verb=GetRecord&metadataPrefix=oai_dc&identifier=oai:dsu-beta.utsc.utoronto.ca:utsc:519

http://dsu-beta.utsc.utoronto.ca/projects/oai2?verb=ListRecords&metadataPrefix=oai_dc

Step 3 - Build a Gateway from WorldCat to Add Records from OAI-PMH

In order to use the Gateway, be sure that the following conditions are met:  

  • Your OAI-PMH compliant repository is running.  
  • You have one or more existing collections with metadata fields mapped to Dublin Core and/or Qualified Dublin Core (dcterms).  
  • You have an OCLC-supplied Key for the Gateway.

If your institution does not already have a Gateway account, Go to the Gateway registration page at http://worldcat.org/digitalcollectiongateway/register.jsp to register your account.

In a few days, OCLC will send a welcome Email that includes user credentials that you can use to log in to the Gateway and add additional users. After you have registered and have received your Gateway user credentials, you can log in to the Gateway and begin synchronizing metadata with WorldCat from your OAI repositories.

After you have registered your account with the Gateway, you need to associate your repositories with the appropriate Gateway key.

  1. Go to the Gateway login page and login http://www.worldcat.org/DigitalCollectionGateway/login.jsp
  2. If you’re not already in the Manage Account tab, click to select it now.
  3. Click Keys and Repositories.
  4. Click to select the key for which you want to add repositories.
  5. Click Add Repository. You’ll see a display something like this:

 

6. When the Add Repository window appears, enter the OAI-PMH base URL for the selected repository. Then click Test.

7. When the repository has been tested successfully, Gateway displays the message “All OAI tests passed.” You can now click Add to associate the repository with your Key.

8. After you have successfully added the repository, you’ll be able to edit and manage settings for the repository you just added.

 

 

In the Repository area of the page, the following information is displayed:  

  • Institution symbol (OCLC symbol)  
  • Gateway license key  
  • URL, name – The OAI-PMH base URL and name of this repository
  • Type – To change the repository type, use the pull-down menu to select one of the following: CONTENTdm (pre version 5), DSpace, Fedora, Eprints, Digital Commons or other. After changing the type, you must click Change to save your choice.

You can use the Show Sets in Collection List? Pull-down menu to configure the way the Gateway harvests content from a repository.

Your OAI repository allows you to manage sets (collections of records) separately in the Gateway. Using sets is the default approach. In the Gateway, a set name is the same as a collection name.

By default, Show Sets… is Yes. This default setting allows you to set up different metadata maps for each collection (or set) in a repository.

If you want to create a single metadata map for all records in your OAI repository, regardless of what collection the records are in, you can select No from the pull-down menu. Selecting No will create a special collection named Entire Repository. When you create a metadata map for that special collection, your mappings apply to the entire repository.  

Note: If you select No, you cannot subsequently undo that setting in the Gateway. For this reason, we strongly recommend that you do not change the default setting. Moreover, with multiple sets you may choose to apply one profile to several (or all) of the sets at any time.

In this example, I select No to apply mappings in the entire repository.

 

9. Since your license key may be used by more than one Gateway user, you can assign users with that key to particular collections. The users can then map metadata and synchronize with WorldCat for each collection to which they are assigned. Then you have to select the type of record processing for this collection and prepare your collection for synchronization with WorldCat through the Gateway.

Then on homepage you will find several sections:  

  • Collection Details – In addition to the general information displayed for this collection, you can set the WorldCat Record Processing type, collection-level record, and more.  
  • Sync Details – You can edit the synchronization schedule for this collection, view its synchronization history, or view a synchronization status report.
  • Metadata Map – You can click the link to edit the collection’s metadata map.  

 

Congratulations! Now you will be able to see your collections in the WorldCat.

The entire repository is avaliable at: http://www.worldcat.org/search?q=on:DGCNT+http://dsu-beta.utsc.utoronto.ca/projects/oai2+DCG_ENTIRE_REPOSITORY+CN7UT&qt=results_page

QA Analysis for Current Repository

Finally, I also did a quality assurance analysis for DSU’s repository. As you can see, the total DC completeness is 73.12%. Some collections need to add dates.

Enjoy your harvesting!

[This post is shared on behalf of Jaclyn DeGasperin, who completed her UofT iSchool practicum at the Digital Scholarship Unit this winter term.]

I knew going into the Practicum course that it would be a challenge for me, I had never worked in a traditional library so this would be a lot of firsts for me (it's a good thing I decided to pick a project that would have me working in a non-traditional library, smart choice on my part) . But when on the list of projects was one called "Building and Assessing Digital Collections in Islandora: 15th century manuscripts" I figured I would give it a shot. With a name like that it was hard to say no; rare books? Yes, please. Digital Humanities? Exactly what I'm looking for. Islandora? I'm sure I can figure it out (this may have been a bad idea, overestimating my abilities to work with technology, but my overeager desire to challenge and prove myself as a competent librarian won out over my other sensibilities)

But here's the thing, I managed, and I can even say that I have the confidence to work with repositories; in a few short months I my knowledge digital repository software went from basically nothing to fairly developed (of course I still have room to grow, hopefully a job will come along that will allow me to meet this challenge, but that's for the future). You see, with supervisors like Lydia and Kim, who genuinely want you to succeed and understand and excel in the field that they themselves love, it's impossible to just coast by and not learn. The environment at the DSU is open and friendly, there was not a day that I came in and wasn't greeted with a smile by one of the wonderful women who worked in the office.

It turns out I like digital librarianship. My work at the DSU started with the Scarborough Oral History Project -- Stories of UTSC:1964-2014, which we started working on in February. The goal of the project was to draw attention to the voices within the UTSC community that are often ignored or overlooked; this project tells the untold and unofficial stories of the University of Toronto Scarborough Campus. It's finished and lives in a tiny corner of UTSC.

As we moved into working with the Gunda Gunde manuscripts our focus shifted from working with the surface of a repository to digging into how a collection is put together, pulling at the guts of Islandora and seeing what makes it ticks (and how to talk to it nicely so it does what you want it to do). For this project we were provided with digital photographs of manuscripts from the Gunda Gunde monastery in Ethiopia; they already had an Islandora collection and had been turned into what can only be called a digital book. It was our job to check that the metadata attached to the images was accurate and that the pages followed in the proper order to match the original artifacts.

While this quality checking was monotonous it provided me with access to wonderfully rare books that I enjoyed flipping through. More importantly though it was a chance to see how a digital repository worked in so far as it is a preservation platform.

Overall my experience with the DSU was positive; it gave me the chance to do work that I would not have otherwise been able to do and experience personal and professional growth. Also, the DSU now has a collection of photogenic animals in its virtual box - you're welcome (I think?).

[The following post is shared on behalf of Julia King, one of the practicum students hosted by the Digital Scholarship Unit this term.]

I went to library school in order to work with rare books. At the start of the degree, my list of courses I expected I would need included coursework in book history, archives, and “digital humanities”, whatever that was. But somehow, through work and school and projects, I found myself in my final semester without actually getting any digital scholarship experience. So, imagine my surprise and delight when I found a project on the practicum list called “Building and Assessing Digital Collections in Islandora: 15th century Manuscripts”! Not only was it digital scholarship, but it was also exactly in my area of research interest!

my emotions [troy] photo myemotions_troy.gif
So, TL;DR, I came into this practicum with a lot of expectations.

So I signed up, made the trek out to Scarborough twice a week, and took my knowledge of digital repository software from absolute zero to being pretty confident in my knowledge and skills. Along with Jaclyn, my fellow practicum colleague and classmate at the UofT iSchool, we jumped into the world of Islandora and digital repositories head first.

We started our work on the Stories of UTSC project, which collected oral histories from members of the UTSC community to celebrate the campus’s 50th anniversary. When we started, what we had were collections of files that were saved onto the Islandora repository (an open source place to store and display files that the DSU uses for most if not all of its projects), and a spreadsheet of data gathered by the undergraduate students who did the interviews as part of a class project. We looked at those spreadsheets, changed them into functional metadata (which is basically data about data, or how information about the objects in the repository is sorted and then made searchable). We then used code magic to “ingest” (my favourite word from the practicum, which makes me feel like we are directing a giant digital Kirby) all of this information and attach it to the files in Islandora.

 


This is basically what an ingest looks like in my brain, but with more XML tags.

Once the metadata was safely attached to the files in the repository, we cleaned it up, added thumbnails, and basically made the collection look presentable for its big unveil in late February.

After this project finished, we jumped into working with the manuscripts. Of course, the DSU isn’t a rare book library, or a physical library at all—we instead take data given to us by professors and store it in a usable way on the internet. So in this case, we had photographs of manuscripts from the Gunda Gunde monastery in Ethiopia, and they had already been ingested into Islandora and turned into essentially a digital book using the Internet Archive Bookreader. Our job was to check that the metadata that was attached to each image was accurate, and that the pages in the book had actually uploaded in the correct order.

Metadata checking is monotonous—you look at a .pdf, and then make sure the fields in your metadata form say the same thing. But, this also was where I used the majority of my rare book skills. For example, I noticed that the “author” field on the form was being used for donor and owner names—so we set up a new section of the form to accommodate this. I made suggestions on improving the system for citing which folios information came from (although this has yet to be resolved, because we couldn’t figure out an easy way to do it that didn’t involve insane amounts of coding or, worse, re-checking all the metadata by hand.)

Checking the page ordering could have been even worse—except that we were actually working with the individual pages, so we were able to experience the manuscripts visually—and there are some stunners in the project. You can look at all of them here, or get a taste through my excited Instagram that I took in March:

As a closing project, we also created our own mock collections in the Islandora virtual box (basically a place where you can test features of Islandora on a fake collection in order to play with the functionality of the repository). This was by far the hardest and most rewarding thing we did on this project. Both the Stories of UTSC project and the Gunda Gunde project were easy enough to figure out—you filled in a form, or uploaded a document. But with this project, we really had to do research and dig deep to understand what exactly the system was doing, and what our collection needed to be like in order to help the system do its thing. We built our own forms for metadata, and had to figure out how to do this within the confines of the extremely confusing Islandora form builder, we figured out how to make our forms autocomplete, and we struggled with the concept of dynamic websites vs. static ones.


Basically, we figured out what the “?” was, where Phase 1 was “ingest items into Islandora”.

Take aways from this experience include:

  • An understanding of what a repository is, and how it can work to organize data online
  • How repositories can be used in the rare books world
  • An introductory understanding of how dynamic websites work vs. static websites
  • A visual understanding of what medieval Ethiopian manuscripts look like
  • A job offer to work on a medieval digital humanities project with another unit at U of T!

This practicum changed my understanding of what my role could be in a library working with rare books, and as you’ve just read, I’ll be continuing on in the digital world working with manuscripts. I am positive that without this practicum, I wouldn’t be able to jump into such a role, and I would recommend anybody with a passing interest in Digital Humanities or metadata to jump at the chance to work here. This is definitely one of the most valuable things I’ve done during the MI degree. The team is very friendly, supportive, and ready to explain anything about digital repositories and the digital scholarship role in the library. This practicum definitely exceeded my expectations of what knowledge and experience I would gain through the course, and I encourage other students to consider choosing to work here or in a similar project in the future!
