(r7) ResourceMetadata < IVOA

This specification will define the minimal data __about__ each resource in registry which must be maintained and queryable.

Should resource metadata be described using [[http://www.w3.org/RDF/][RDF]]? Just the name, __Resource Description Framework__, seems to fit the bill. Would make it easier to transition any metadata into an ontology described using [[http://www.w3.org/TR/owl-absyn/][OWL]].

---++ Comments
Anyone wanting to look into RDF can look at the [[http://www.w3.org/TR/rdf-primer/][RDF Primer]], which is now in a new version (Working Draft 23 January 2003) -- TonyLinde - 28 Jan 2003

Another link to check out for RDF is [[http://www.ilrt.bris.ac.uk/discovery/rdf/resources/][Dave Beckett's Resource Description Framework (RDF) Resource Guide]]: it is *huge* -- TonyLinde - 28 Jan 2003

   * Resource Metadata (folks working parallel efforts in this area are encourages to add pointers 
     below.)
      * VOResource
         * based on [[http://www.ivoa.net/internal/IVOA/Registry19032003/ResourceServiceMetadataV6.pdf][RSM]] 
           document by Hanisch et al.
         * Current version: [[http://rai.ncsa.uiuc.edu/~rplante/VO/schemas/VOResource.xsd][VOResource.xsd]]

   * Space-Time Metadata
      * Arnold's [[http://hea-www.harvard.edu/~arots/nvometa/SpaceTime.html][Space-Time Coordinates page]] describes the current model and includes a link to a [[http://hea-www.harvard.edu/~arots/nvometa/coords.dtd][DTD]].
      * The current version of the regions schema can be seen as a [[http://hea-www.harvard.edu/~arots/nvometa/region.dtd][DTD]].

   * AstroGrid Registry

---++ Metadata Specifications

Metadata specification efforts are under development within the [[IVOARegWp03][RWG work package 3]].  It has two components:

   * core resource metadata concepts, independent of any encoding scheme.  See [[%WIKIHOMEURL%/Documents]] for the latest recommendation currently going through the IVOA Standardization process.  

   * XML Schemas:  see [[IVOARegWp03#Specifications]] for latest versions
