Two large language resource metadata systems-to-be in Europe:
http://www.clarin.eu/external/ (go to VLO)
http://www.meta-net.eu/ http://www.meta-share.org/ http://metashare.csc.fi/
CLARIN has the component metadata model.
http://www.clarin.eu/cmdi http://catalog.clarin.eu/ds/ComponentRegistry/# http://www.isocat.org/
META-SHARE has (will have) a defined content model for metadata
META-SHARE nodes provide an editor for resoureInfo records.
Records can be published directly from the editor.
UHEL node: http://metashare.csc.fi
CLARIN uses OAI-PMH to provide records for harvesting
META-SHARE nodes will synchronize with each other automatically
I see three issues in sending META-SHARE records to CLARIN:
Shifting from resourceInfo to CMDI/ISOCat should be straightforward:
Most likely implemented as XSL Transforms (XSLT). Identify the META-SHARE records as the original.
http://metashare.ilsp.gr/portal/knowledgebase/resourceInfo
http://catalog.clarin.eu/ds/ComponentRegistry/# http://www.isocat.org/
Records in META-SHARE get edited, sometimes removed.
CLARIN OAI-PMH providers must track the changes to an existing record accurately.
(Different records on the same resource are not a major issue. Also, they may be detected by persistent identifiers, but hardly resolved automatically.)
META-SHARE plans to have an identifier for each record.
It may not be the right kind, though.
So there may be a problem. Not sure. Wait for v3, this summer.
When a META-SHARE record is considered by an OAI-PMH provider for CLARIN:
If already there:
If not there, add it as a new item with a new OAI-PMH identifier
When a META-SHARE record is already in an OAI-PMH provider:
Might notice absence of old record, presence of new, but don't really want a trail of deletions when there have really been only changes.
How do we notice when a new META-SHARE record is available for CLARIN? Scenarios:
At least some of the records there are ours.
META-SHARE has a defined content model with a supporting editor for describing language resources. META-SHARE synchronizes itself.
CLARIN has a compatible but flexible format and semantics. CLARIN harvests its own providers.
We are in both. We desire a bridge.
