- 2. 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” DCMI Abstract Model http://dublincore.org/documents/abstract-model/ Expressing DC metadata using RDF http://dublincore.org/documents/dc-rdf /

- 5. “ 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

DCMI Description Set Profile (DSP) The Singapore Framework for Dublin Core Application Profiles http://dublincore.org/documents/singapore-framework/ 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

DSP & Schematron XSLT Transform to map DSP constraints into Schematron schema for DC-DS-XML http://dublincore.org/architecturewiki/DSPDCDSXMLSchematron See also http://efoundations.typepad.com/efoundations/2009/09/experiments-with-dsp-and-schematron.html Could do similar for (profile of?) RDF/XML? Could generate SPARQL ASK queries? Only for subset of constraints?
