Documentation of dc_accessrights* attributes?

Hi there,

there are some different attr_dc_accessrights* -attributes in zms-code
but I cannot find them documented anywhere.

Greping through the code finds these different ones:

attr_dc_accessrights_restrictededitors
attr_dc_accessrights_public
attr_dc_accessrights_restricted

Some info about the other attributes would also be interesting
especially how they interact with the ZMS:

attr_dc_coverage
attr_dc_identifier_doi
attr_dc_description
attr_dc_creator
attr_dc_type
attr_dc_identifier_url_node
attr_dc_metacmds

Thanx and regards
