[UPDATE: This meeting IS happening and is now scheduled for Tuesday, April 5 from 9-10am in Wells Library 043. Apologies for missing the meeting where this was originally scheduled but this thing is BACK ON! And don’t forget to check out Jennifer’s post discussing More about MODS (and XML) to learn more about MODS and its uses before we meet.]
It’s been a while since the Metadata Discussion Group last met but Jennifer and I think we have something that could benefit from a few more metadata-aware eyes at IU. If that’s you, or if you’re interested in topics like transforming metadata or linked library data, read on!
There is an ongoing effort in the Hydra community to figure out strategies to deal with descriptive metadata in RDF for use in Fedora 4 (the digital object repository that we hope to upgrade to here at IUB Libraries). The MODS and RDF Descriptive Metadata Subgroup, lead by Steven Anderson from the Boston Public Library, is working on how to handle MODS XML as RDF that will create a usable, if unofficial, metadata application profile to bring MODS into Fedora 4 as RDF properties.
So far this work has involved going through MODS element by element using examples from various institutions and asking the question “If [you] had to move that [MODS element] to RDF in Fedora 4 today, what would [you] chose to do with it?” (see the work for Abstract as an example). The MODS elements examined so far include name, title, typeOfResource, genre, originInfo, physicalDescription, abstract, language, and current work is happening on tableOfContents.
Join us on Tuesday, April 5 from 9-10am in Wells Library 043 to learn about this effort and Indiana University Libraries’ participation. We’ll share contributed examples and discuss how the MDG might help this effort along for IU and the Hydra community.
The Metadata Object Description Schema (MODS) Editorial Committee announced the posting of a draft MODS/RDF ontology. MODS, a descriptive metadata schema that is loosely based on MARC, is widely used to describe objects in libraries, archives, and museums. The new MODS/RDF ontology promises to usher MODS (and bibliographic data) into the realm of linked data. The MODS namespace has been under development for some time. The timing of the release of the MODS/RDF draft seems to be in response to the recent launch of BIBFRAME.org.
The MODS/RDF ontology homepage includes links to a primer, the MODS/RDF namespace document, and examples of MODS/RDF records. For those wanting to test drive the transformation of MODS/XML files to MODS/RDF, there is a stylesheet available as well.
The MODS Editorial Committee welcomes feedback on the draft ontology via the MODS listserv, where a number of MODS implementers have already commented on the draft.
MADS: Successful Linked Data Implementation
The MODS companion schema for authority data, Metadata Authority Description Schema (MADS), has already been published as linked data via the Library of Congress Linked Data Service. Click on the screenshot below to go to the authority record.
Last week NISO announced that their Spring/Summer issue of Information Standards Quarterly (ISQ) is available online: www.niso.org/publications/isq
This issue focuses on linked data in the cultural sector, is guest edited by Corey Harper, and contains articles written by some Metadata Discussion Group Superstars.
Remember the MDG meeting from October, 2011? We discussed our impressions from Free Your Metadata, a video by Seth van Hooland, Max De Wilde, and Ruben Verborgh (and with very kicky music). The authors are included in this issue of ISQ where they discuss in greater detail how they used Google Refine to tidy up and reconcile data efficiently.
This issue also includes the following articles:
- A feature article by Gordon Dunsire, Corey Harper, Diane Hillmann, and Jon Phipps on Linked Data Vocabulary Management.
- Jane Stevenson in Linking Lives describes the work to enable structured and linked data from the Archives Hub in the UK.
- Ted Fons, Jeff Penka, and Richard Wallis discuss OCLC’s Linked Data Initiative and the use of Schema.org in WorldCat to make library data relevant on the web.
- In Europeana: Moving to Linked Open Data , Antoine Isaac, Robina Clayphan, and Bernhard Haslhofer explain how the metadata for over 23 million objects are being converted to an RDF-based linked data model in the European Union’s flagship digital cultural heritage initiative.
- Jon Voss provides a status on Linked Open Data for Libraries, Archives, and Museums (LODLAM) State of Affairs and the annual summit to advance this work.
- Thomas Elliott, Sebastian Heath, John Muccigrosso Report on the Linked Ancient World Data Institute, a workshop to further the availability of linked open data to create reusable digital resources with the classical studies disciplines.
- Kevin Ford wraps up the contributed articles with a standard spotlight article on LC’s Bibliographic Framework Initiative and the Attractiveness of Linked Data. This Library of Congress-led community effort aims to transition from MARC 21 to a linked data model.
Issue 16 of the Code4Lib Journal is out today. Of interest to this group might be the following article:
Westrum, A., Rekkavik, A., & Tallerås, K. (2012). Improving the presentation of library data using FRBR and linked data. Code4Lib Journal, 16. Retrieved from http://journal.code4lib.org/articles/6424
This month, the group discussed how LAMs might address legacy data problems in preparation for a potential move to linked data. Resources to be consulted in preparation for January’s meeting can be found here.
Discussion opened with Continue reading “Summary of January meeting”
The Library of Congress’ Bibliographic Framework Transition Initiative released news today of a General Plan (10 pages) outlining requirements and a timeline for the effort to replace MARC, the carrier for library data:
The new bibliographic framework project will be focused on the Web environment, Linked Data principles and mechanisms, and the Resource Description Framework (RDF) as a basic data model (p. 4).
The report identifies XML as the preferred metalanguage for this future bib framework. In addition, the report mentions examining other initiatives including PREMIS (Preservation Metadata Implementation Strategies), METS (Metadata Encoding Transfer Standard), MODS (Metadata Object Description Schema), and MADS (Metadata Authority Description Schema) and how each of these are expressed (or might be expressed) in RDF.
In her cover note, Deanna Marcum, Associate Librarian for Library Services at the Library of Congress, asks for comments on the general plan and recommendations for advisory or technical committee members.
Naturally, discussion is welcome here too!
