  1. Metadata Grammar:Towards convergence between Dublin Core and RDF Thomas Baker <thomas.baker@gmd.de> GMD -- German National Research Center for Information Technology 30 March 2000

  2. Dublin Core (without Qualifiers) Objects have Elements (properties). Object? Document-like Objects (1996) Information Resources (2000) HASA HASA HASA HASA Element Element Element Element Name Creator Title Type Date Value "T. Mustermann" "Travel report" "Text" "2000-03-07" Elements have Names and Values.

  3. Value Encoding Schemes Object? Resource HASA HASA HASA HASA Element Element Element Element Creator Title Type Date "2000-03-07" Says that the string "2000-03-07" is formatted according to a W3C profile based on ISO8601. VES W3C-DTF

  4. Element Refinements Object? Resource HASA HASA HASA HASA Element Element Element Element Creator Title Type Date ISA "2000-03-07" Specifies that the Date associated with the resource is the Date Created. ER VES W3C-DTF Created

  5. Value Components? Object? Resource HASA HASA HASA HASA Element Element Element Element Creator Title Type Date "T. Mustermann" HASA HASA Were proposed as a type of Qualifier. Specify that T. Mustermann is a Person who works at GMD. VC VC Type Affiliation "Person" "GMD"

  6. No, let's move them to... Object? Resource HASA HASA HASA HASA Element Element Element Element Creator Title Type Date "T. Mustermann" HASA HASA VC VC Type Affiliation "Person" "GMD"

  7. ...a People (or Agent) Core Element Set Object? People-like Objects? HASA HASA HASA HASA Element Element Element Element Name Name Affiliation Type Birthdate Value "T. Mustermann" "GMD" "Person" "1947-03-30"

  8. DCMI sees Elements and Qualifiers DCMI has had no grammatical term for the high-level "object" ?? HASA HASA HASA HASA Element Element Element Element ISA Qualifier Qualifier Element Refinements Value Encoding Schemes are both "Qualifiers"

  9. RDF sees Resources, Relations, and Classes Should DCMI define a grammatical entity, "Class"? Class Information Resource ISA HASA HASA HASA Resource Resource Class Resource Type Date ISA "Text" Should DCMI redefine Type as a "Class Refinement"? Resource Class W3C-DTF Date Created
