Dear all, This is a bit OT, but at least about metadata: I am curently preparing some data in TCS schema and I plan to set up a OAI interface for data exchange. According to the OAI specifications the use of dublin (NOT darwin..) core formatted metadata is obligatory, so I will also try to offer oai_dc metadata. I would like to ask the group if there have been any discussions on mapping TCS to DC before? Do you know of any attempts to model concept or name metadata with DC? many thanks in advance, Robert -- Dr. Robert Huber, WDC-MARE / PANGAEA - www.pangaea.de Stratigraphy.net - www.stratigraphy.net _____________________________________________ MARUM - Institute for Marine Environmental Sciences (location) University Bremen Leobener Strasse POP 330 440 28359 Bremen Phone ++49 421 218-65593, Fax ++49 421 218-65505 e-mail rhuber@wdc-mare.org
