I guess you mean separating custom and Lenya metadata cleanly, right?
Or otherwise can you explain a bit.
I think we should not separate between "internal" ("Lenya") and
custom meta data, but we should allow to use meta data sets which
are identified by namespaces.
Some examples used by the core are:
- DublinCore elements
- DublinCore terms
- workflow-related meta data
- access-control-related meta data
- content item meta data (e.g. resource type, source extension, mime type)
- image-specific meta data (e.g. width, height)
Resource types and other components could declare additional meta data
sets for specific purposes, e.g.
- access permissions in certain environments
- content descriptions
- information about search indexing (how, when, ...)
A meta data element set consists of a set of attribute keys
and is identified by a namespace.
