DC-2005: International Conference on Dublin Core and Metadata Applications

Metadata based on standards such as Dublin Core are a key component of information environments from scientific repositories to corporate intranets and from business and publishing to education and e-government.

DC-2005 to be held in Madrid at University Carlos III (September 2005, 12-15) will examine the practicalities of maintaining and using controlled sets of terms ("vocabularies") in the context of the Web.

DC-2005 aims at bringing together several distinct communities of vocabulary users:
* Users of metadata standards such as Dublin Core and Learning Object Metadata (LOM), with their sets of descriptive "elements" and "properties"
* The W3C Semantic Web Activity, which has formalized the notion of "ontologies"
* Users of Knowledge Organization Systems, which encompass value-space structures such as "thesauri" and "subject classifications"
* The world of corporate intranets, which use "taxonomies"
These diverse communities share common problems, from the the use of identifiers for terms to practices for developing, maintaining, versioning, translating, and adapting standard vocabularies for specific local needs.
Then, let's discuss about in DC-2005 Conference

Wilshire Metadata Conference 2004 Trip Report

Not all metadata are created equal as I learned last year when I attended the Wilshire Metadata & DAMA International Conference in Orlando, FL. However, when I sat in their meetings and learned this new aspect of metadata I discovered that there are some similarlities of concern, basically information organization, management, access, and retrievable.

If you come from the database modeling/administration world, I hear this is their equivalent to the IA Summit or CHI. The 2004 just concluded in Los Angeles. Their trip report is very informative, with enough information to get you to dig into new ways of thinking about information management.

Building a Metadata-Based Website

From Boxes and Arrows: Building a Metadata-Based Website - The online world has been flooded in recent years with talk of metadata, structured authoring, and cascading style sheets. The idea of a semantic web is gaining momentum. At the confluence of these two broad categories of activity, new models of websites are emerging.

Brett Lider's talk at the Summit was great - now folks who couldn't make it can see the early horizon for next-generation CMS.

Practical RDF Book & Site

This site was recommended by a fellow engineer at work. It's basically the support/info site for the O'Reilly Book Practical RDF by Shelley Powers et al. They have chapter samples online and it's an interesting practical perspective in applying RDF. Many other resources are mentioned that supplement the book's offerings.

Diagramming software

I've been reminded of AT&T Labs' GraphViz again, most recently by a Drupal developer who's writing code to draw diagrams from Drupal's database. Lately, my organization has been pushing to get reports of user data. The reports we get generated from our sysadmin are mostly raw dumps of data that have some columnar formatting. What we're looking at right now is using log files to auto-generate diagrams that show usage data. Should be fun. If you've done this sort of thing with GraphViz before I'd love to hear about your experience. I've downloaded the Mac OS X package and am learning the languages now.

Other semi-automated diagramming packages (gleaned from the Tulip site).

Ideagraph - interesting project for semantic/RDF/topic map folks

Ideagraph is a "Personal Knowledge Manager" that is in early beta. It is intended to eventually be a commercial product, but is currently free to download.

Semantic search project for Moveable Type

From Ben and Mena

Maciej Ceglowski has built a prototype for a semantic search engine. To adapt it to function as a Movable Type plugin, he needs sample content that he can test against.

If successful, the search feature would let you do a keyword search, and get back relevant results even when there was no exact keyword match.
If you use Moveable Type, and you'd like to help out, send him some content.

Maciej is using latent semantic analysis to enable local search beyond keyword indexing. Sounds like an ambitious and exciting project.

Dublin Core Conference 2003

Just saw the call for papers for the 2003 Dublin Core Conference(Seattle, WA) that will be held September 29 - October 2, 2003.

Eric Miller on the Semantic Web

Peter V. pointed to this interview on New Breed Librarian with Eric Miller, which provides a concise definition of the Semantic Web and examples of how it would be realized in applications.

Thanks, Peter. I found the examples helpful as I still attempt to grok how this will be used in the real world. Thanks Eric for reminding me to link to it. Duh.
