A number of the organizations likely to be represented at the DC-2012 use a Drupal platform (e.g., FAO and VIVO) or are planning such a migration (ZBW Labs and DCMI). This special session would explore the relationship between Drupal and Linked Open Data (LOD) vocabularies—specifically, how Drupal systems can ingest and use LOD vocabularies and publish data using LOD vocabularies. How does, or how might, Drupal interact with the Agrovoc Vocbench, AgInfra tools, metadata registries, or Schema.org?

  • Ingesting and displaying Linked Open Data from SPARQL endpoints using Drupal extensions such as views, sparql_views, and rdfx (e.g., see Lin Clark's video, linked below).

  • "Web Taxonomy", a Drupal module for integrating excerpts of terminologies from the LOD cloud as taxonomies for referencing in Drupal RDFa. It has been suggested that Agrovoc, with its large set of supported languages, might use the Web Taxonomy module to index in one language, then automatically update and display labels in all supported languages.

  • "Economics Taxonomies", a Drupal plugin under development by ZBW Labs, which leverages JSON responses from external autosuggest Web services and SPARQL endpoints.

  • "Neologism", a Drupal module from DERI, which pushes vocabularies into the LOD cloud.

  • "AgrovocField", a Drupal module that connects to the Agrovoc web services built on the VocBench and provides a user-friendly widget with an autocomplete box. In future, will support automatically tagging a node field (textarea, file attachment or web URL) using the Agrotagger web +services based on Agrovoc.

  • "Autotagging" and "Textmining_API", early-beta Drupal modules that support using 3rd party services for automatic indexing and are designed to be extensible by plugging in other services.

  • "Schemaorg", a Drupal 7 module.

  • "schemaorg_kickstarter", a Drupal 7 distribution that already includes content types with typical mappings to schema.org classes and properties.

The session would begin with lightning talks about projects that use or are implementing any of the approaches above. These presentations would lead into "unconference"-style brainstorming to identify opportunities for sharing expertise, pooling efforts, or defining joint goals.
