Join the next Metadata Discussion Group meeting for a look at metadata and discovery layers. While we often talk about the need for metadata standards to share our information, discovery layers – meant to help users search, browse, and find what they need within our collections – often don’t really care about a metadata standard as long as the metadata coming in is consistently identifiable for that discovery layer’s index.
Indexing using Apache’s Solr search platform is a common method to provide faceted searching and browsing in many library/online resource contexts (IUCAT, the IUB Libraries’ web site, and Media Collections Online all have Solr indexes behind them, for example). The source of metadata that feeds each of the indexes in those examples is different, however. We’ll take a look at how these sites are handling discovery differently while using similar tools and what it could mean in terms of discovery to combine these different types of library data sets.
DATE: Tuesday, November 11
PLACE: Wells Library Room 043
TOPIC: Metadata and Discovery Layers
MODERATOR: Julie Hardesty
For examples of what others are doing along these routes, you can take a look at UW-Madison Libraries and Stanford University Libraries discovery layers, paying particular attention to how they provide discovery and access to collections available online.
NISO recently announced the winter 2013 issue of Information Standards Quarterly (ISQ) is available and its theme is the evolution of bibliographic data exchange. This issue is edited by OCLC’s Ted Fons and is freely available on the National Information Standards Organization (NISO) ISQ site.
The Metadata Discussion Group (MDG) tackled BIBFRAME in our October discussion and we agreed that we would like to see more concrete examples of BIBFRAME in action. Therefore, I was thrilled that Jackie Shieh wrote about George Washington University Libraries experience as an early experimenter in the BIBFRAME initiative. While is article focuses more on the administrative side, it is possible that we will start seeing the results of these early experimenters soon. Zepheira and LC’s 2014 plans for BIBFRAME focus on software development and demonstrations, as well as short-term analysis of lingering issues.
It is difficult for library staff to comprehend and anticipate how linked data will affect our workflow, the display of our bibliographic records, and user access/retrieval. I feel like BIBFRAME is a massive trust exercise and we cross our fingers that those who are building and tweaking the model are leading us in the right direction. But, we should try to read as much as possible on the subject since it impacts us greatly. NISO webinars and their publications have been good resources for us on best practices in the library community.
There are two Linked Data presentations from ALA Midwinter available.
The January 26th 3-4PM session Linked Data for Holdings and Cataloging: The First Step Is Always the Hardest! recording is quite good. Eric Miller (Zepheira) and Richard Wallis (OCLC) are the presenters of this linked data session.
Miller’s presentation discussed the importance of defining clear relationships; plus, more contextual information on the web will allow libraries to share their amazing collections via common search engines (holdings). He then touches on BIBFRAME and how the data model aims to be nimble enough to support the work of the past 50 years and the challenges of the next 50 years.
Wallis discussed Schema.org–a vocabulary for describing webpages that was produced by major search engines. OCLC chose Schema.org for their WorldCat linked data project because of Schema.org’s broad adoption by the likes of Google, Yahoo! and Bing. Wallis goes on to state that while this vocabulary is not robust enough for libraries, we aren’t limited to using only one standard with linked data–they intermix.
He illustrated how the WorldCat linked data project helped make more obscure items (like dissertations) show up on the first page of a Google search. Plus, he briefly discusses the following data sets OCLC made available as linked data last year: Dewey Decimal Classification, FAST, and VIAF.
The second part of this presentation is audio, but the links associated with the speakers contain their slides. Violeta Ilik (Texas A&M University Library) & Jeremy Myntti (Head of Cataloging & Metadata Services at University of Utah – J. Willard Marriott Library) separately tried some small linked data projects using the Viewshare tool.
Viewshare is a service provided by LC for digital collections. It helps users generate and customize views (using interactive maps, timelines, facets, tag clouds) so users can interact more with the collection. Both speakers discovered some interesting trends and inconsistencies in their metadata. Good stuff!
The next Metadata Discussion Group meeting will be on Tuesday, February 5, from 9:30—10:30 in the Wells Library, Room 043.
BIBFRAME, a data model resulting from the work of Library of Congress Bibliographic Framework Transition Initiative, is meant to envision a data universe that may one day supersede MARC, the carrier of library data. This month, we’ll talk about BIBFRAME developments, namely, the recent unveiling of bibframe.org.
DATE: Tuesday, February 5
TIME: 9:30–10:30 am
PLACE: Wells Library 043

The Wikipedia community has approved the automated addition of links to VIAF in Wikipedia articles. The proposal was spearheaded by the OCLC Wikipedian in Residence, Max Klein and the British Library Wikipedian in Residence, Andrew Gray. There’s a video summary of the proposal YouTube.
Approximately 4,000 Wikipedia author articles already link to VIAF. See the article on Mark Twain (scroll down to the bottom of the page to see links to VIAF as well as links to the German National Library’s authority file (PND), LCCN, and WorldCat Identities. The VIAF record for Mark Twain links back to Wikipedia (expand the About box).
