More Comments on TLA

The drive from Houston to Dallas was beautiful. The blue bonnets had past, except for a few scattered patches. However, the brown eyed susans, winecups, indian paintbrushes, and a white flower (cow's parsley?) were spectacular.

At the RDA preconference I had the pleasure of heading Carol Seiler, from AMIGOS, speak. Great presentor.

DCMI Abstract Model

At the RDA preconference I noticed that RDA seems to have been based, at least in part, on the DCMI Abstract Model. I knew RDA had some basis in FRBR, but this was something new to me. Getting to know the DCMI Abstract Model before RDA hits has been added to my to-do list.
This document specifies an abstract model for Dublin Core metadata. The primary purpose of this document is to specify the components and constructs used in Dublin Core metadata. It defines the nature of the components used and describes how those components are combined to create information structures. It provides an information model which is independent of any particular encoding syntax. Such an information model allows us to gain a better understanding of the kinds of descriptions that we are encoding and facilitates the development of better mappings and cross-syntax translations.

LCSH Suggestion Blog-a-Thon

The Radical Reference folks are having a Library of Congress Subject Heading Suggestion Blog-a-Thon.
Do subject headings still matter? We say they do.

Does the Library of Congress always identify accessible and appropriately named headings and implement them in a timely manner? We say not always. All you have to do is spend one day behind a reference desk to see examples of biased, non-inclusive, and counterintuitive classifications that slow down, misdirect, or even obscure information from library users. As librarians and library workers, providing access to information is important-and classifying it in ways that are inclusive and intuitive strengthens our egalitarian mission.

Between now and Sunday, April 27, Radical Reference invites you to suggest subject headings and/or cross-references which will then be compiled and sent to the Library of Congress. You can either choose one previously suggested by Sandy Berman (pdf or spreadsheet) or propose your own.

This is a chance to positively impact the catalog of the de facto national library of the United States, which also impacts cataloging all over the world!

Recommender System for the DSpace

A Recommender System for the DSpace Open Repository Platform by Desmond Elliott, James Rutherford, and John Erickson. HPL-2008-21.
We present Quambo, a recommender system add-on for the DSpace open source repository platform. We explain how Quambo generates content recommendations based upon a user selected set of examples, our approach to presenting content recommendations to the user, and our experiences applying the system to a repository of technical reports. We consider how Quambo could be combined with the peer-federated DSpace add-on to extend the item-space from which recommendations can be generated; a larger item-space could improve the diversity of the set from which to make recommendations. We also consider how Quambo could be extended to add collaboration opportunities to DSpace. Publication Info: Submitted to Open Repositories 2008, Southampton, UK, April 1-4, 2008

TLA Recap

TLA is over for the year. Always an excellent conference. Here are a few observations. The RDA preconference had 135 registered. Some had to be turned away, the most the room would hold was 135. There is definitely an interest in this.

Walt Crawford shows that common sense is not so common but in the right forum always interesting.

No graphic novel/comic vendors. No Marvel, DC, Antarctic Press, Strangers in Paradise. Missed them. Rod Espinosa did a presentation and autograph session. And the author of American Born Chinese did a presentation. Have to check out his stuff, very well-spoken.

The keynote panel was fun. Roy Tennet was a very good moderator.

OPALS looks like an open-source ILS worth investigating.

Post any failures at the Library Success wiki. Examples of things that did not work and even better info on why are important and useful to others.

The KIC copier looks interesting. Too expensive for us right now, $20,000 or so. But a flat scanner that produces a PDF or TIFF and then can email or move the file to a thumb drive looks like the future.

The Nasher Sculpture Center is a beautiful setting. The Willows, Irises and water at the end of the row Oaks was stunning.

The District Caucuses were the same time as the alumni dinners. I went for the dinner. Nice view from the 69th floor.

TLA 2009

It looks like the Lunar and Planetary Institute (LPI) Education Dept. will be having a preconference at TLA 2009. Explore! Fun with Science. Never too early to get this penciled in your daytimer.

RDF Tool

RDFify your data wtih Triplify.
Triplify provides a building block for the "semantification" of Web applications. Triplify is a small plugin for Web applications, which reveals the semantic structures encoded in relational databases by making database content available as RDF, JSON or Linked Data.

Triplify is very light weight: It consists just of few files with less than 500 lines of code. For a typical Web application a configuration for Triplify can be created in less than one hour and if this Web application is deployed multiple times (as most open-source Web applications are) the configuration can be reused without modifications.

Triplify makes Web applications easier mashable and lays the foundation for next generation, semantics based Web searches.

23 Things

23 Things is all the rage among the Library 2.0 folks. I had an idea, how about 23 Things for the Semantic Web? COinS, Microformats, RDF, Topic Maps, SKOS, etc. There would be plenty to investigate. Not sure the concept could be grasped quite as fast though.
