Title: DCMI Usage Board Review of Application Profiles Creator: Thomas Baker Identifier: http://dublincore.org/usage/documents/2003/02/11/profiles/ Latest version: http://dublincore.org/usage/documents/profiles/ Date modified: 2003-02-11 Description: This document defines the term "Application Profile" in the context of the Dublin Core Metadata Initiative. Criteria for Usage Board review of Application Profiles and guidelines for submission are outlined in the DCMI Usage Board Administrative Processes document [PROCESS]. "Application Profile" defined For the purposes of DCMI Usage Board review, an Application Profile (AP) is a declaration of which metadata terms an organization, information resource, application, or user community uses in its metadata. Moreover: -- By definition, an AP cannot "declare" new metadata terms and definitions; it only "reuses" terms from existing element sets [HEERY]. -- The ideal element set will use URIs to uniquely identify its terms within XML namespaces [DCMI-NAMESPACE]. As of 2002, however, this cannot be required. -- By definition, any new term coined for use in an AP must first be declared in a form citable in the AP. -- An AP may also provide additional documentation on how the terms used are constrained, encoded, or interpreted for particular purposes. As of 2002, APs are seen primarily as a form of documentation, the purpose of which is to help implementor communities harmonize their metadata practice. It is hoped that in the longer term, machine-processable versions of such APs based on data models such as RDF will provide a basis for automating metadata interoperability functions such as semantic crosswalks and format conversions.
