Add language-related metadata standards as used by CLARIN

[alex-ball]

(From a suggestion by Marion Wittenberg and Angus Whyte)

CLARIN normalises the metadata it holds using the Component Metadata Infrastructure (CMDI). This is really a wrapper around a metadata record, providing (among other things) explicit links/identifiers to the metadata profile used and the thing being described.

The profiles themselves are documented in the CLARIN Component Registry. The metamodel used in the registry is that a component corresponds to a thing, an element is a property of a thing, and components may be nested to show relationships between things. A profile is, in effect, a component that corresponds to a thing a CMDI record might describe. Elements should be linked to a description of their semantics.

There are profiles in the Component Registry for the following standards relevant for language resources:

• Dublin Core Terms (already included) and OLAC (Open Languages Archives Community)
• IMDI (ISLE Metadata Initiative) – Wikipedia has a list of use cases
• TEI (Text Encoding Initiative) headers
• Meta-Share maximal and minimal records
• MODS
• PARADISEC

The DCC has offered to work on the following entries:

• Component Metadata Infrastructure (CMDI) [as a standard]
• CLARIN Component Registry [as an extension to CMDI]
• OLAC [as a standard]
• IMDI [as a standard] or Meta-Share [as a standard]

This leaves TEI headers, MODS and PARADISEC unassigned.
