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
