Library of Congress releases LCSH as linked data

Yesterday the LOC announced it is releasing it's first service on id.loc.gov which contains LCSH terms represented as RDF/XML, N-Triples and JSON.

The vocabulary is available for download, or can be searched online at http://id.loc.gov/authorities/

Here are some sample snapshots:

---

Search for "simple machines"

---

View for the topical term "Simple machines". Note you can export the term as RDF, N-Triples or JSON.

---

Each term has a "Visualization" tab which shows related, broader and narrower term relationships.

Article on Drupal and RDF

A great article that simplifies what the fuss over RDF/RDFa is about, and how Drupal is trying to tie into it.

Auto-tag your content with Calais for Drupal

This is rebooting my interest in automated classification. =)

Check out the Calais Drupal module, based on the Calais service from Thomson-Reuters.

The Calais modules for Drupal (found at http://drupal.org/project/opencalais) are feature-rich, highly intuitive and designed to make it easy for Drupal users to automatically metatag their content, generating rich Semantic metadata that can be shared via a simple key and integrated into the larger content universe.

The screencast shows what an implementation would look like. I'm ready to use Drupal's RSS aggregator or FeedAPI module to pull in some content and see how Calais auto-tagging would work.

Of course, now I want to see what Calais does to library items imported into Drupal, see how Drupal would expose RDF and other stuff!
