Earliest schemas
were largely conceptual in
|
|
nature:
|
|
|
|
– |
e.g. Pittsburgh
BAC model, Cedars outline
|
|
|
specification,
OCLC/RLG WG
|
|
|
• |
Gradually moving
towards a more practical
|
|
|
focus:
|
|
|
|
– |
e.g., VERS, NLNZ,
METS, PREMIS
|
|
|
|
– |
Based on XML
(DTDs and Schemas)
|
|
|
• |
But there is an
urgent need for this
|
|
|
experience to be
shared
|
|
|
|
– |
e.g., briefing
papers, advice to implementers
