Dublin Core Description Set Profiles

Dublin Core Description Set Profiles VoCamp, Bristol

Dublin Core

Historically, informal notions of

Making statements “about” things

Sets of statements forming logically bounded units e.g. “description of document” v “description of person”

Values often drawn from “controlled lists” explicitly named in statements (“vocabulary encoding scheme”)

Datatypes (“syntax encoding schemes”)

“ Grammatical Principles”

“ DC application profiles”

Specification of how metadata used to meet needs of community/domain/application

Documentation function

“ Validation”

Data creation tools

“ Mixing” terms from multiple vocabularies

e.g. DC terms + FOAF + SKOS

“ Matching” terms in combination

e.g. statements using property dcterms:subject should use VES dcterms:LCSH

e.g. statements using property dcterms:created should use SES xsd:date

Occurrence

e.g. a description of a person must provide a statement using property foaf:name

e.g. a description of a book must provide two statements using dcterms:abstract, one with value in English, one with value in French

Informal guidelines

Description Set Profiles: A constraint language for Dublin Core Application Profiles

http://dublincore.org/documents/dc-dsp /

Working draft by Mikael Nilsson

Specifying structural constraints on a description set

the resources that may be described by descriptions in the description set

the properties that may be referenced in statements

the ways a value surrogate may be given

Description templates, statement templates

Algorithm for matching description set to templates

Could do similar for (profile of?) RDF/XML?

Could generate SPARQL ASK queries?

Only for subset of constraints?
