Hi Marian: Here is a general explanation of what you experienced:
Support for basic OAI-PMH (which is the protocol on which the oai2rdf tool relies) only requires that 1 metadata format be supported - 'oai_dc' (unqualified Dublin Core). All others are optional and the edoc server you tried supports 2 others (oai-ems and oai_pp). But since you requested specifically the 'rdf' format, it skipped all these. The 'rdf' format is only available for DSpace systems that are specially configured, not all OAI providers. However, you can try that server with this invocation: /oai2rdf.sh -m oai_dc http://edoc.bbaw.de/OAI data which should still give you some RDF metadata, just not as rich as the 'rdf' format. Let me know if this doesn't make sense, Richard Rodgers On Mon, 2007-11-19 at 13:45 +0100, Marian Thieme wrote: > Hello, > > I am quite new to dspace and longwell, I would like to have a test to > see how it can work.
