4  Key standards used by MAF

4.1  ISO 12620 Data Category Registry (DCR)

The designers of any specific MAF tagset shall use data categories from the ISO 12620 DCR. The DCR is a set of data category specifications defined by ISO 12620 and maintained as a global resource by ISO TC 37 in compliance with ISO/IEC 11179-3:2003. Tagset creators can define a set of new data categories to cover data category concepts that are needed and that are not currently available in the DCR. The tagset creators shall be responsible for negotiating the addition of the new data categories to the DCR. This supplemental set of data categories shall be represented and managed in conformance with ISO 12620.

4.2  ISO 24610 Feature Structures (FSR and FSD)

Morpho-syntactic content shall be expressed using the ISO 24610 part 1 document on Feature Structure Representation and validated using the future ISO 24610 part 2 companion document on Feature System Declaration.

4.3  OLAC Metadata

Metadata for MAF shall be expressed following the recommendations and categories proposed by the Open Language Archives Community (OLAC), as described in the latest version of OLAC Metadata Standard (http://www.language-archives.org/OLAC/metadata.html). The OLAC Metadata Set includes the Dublin Core Metadata Set with qualifiers.

4.4  Unified Modeling Language (UML)

MAF complies with the specifications and modeling principles of UML as defined by OMG. MAF uses the subset of UML that is described in Annex E.
