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.
