Alan,

My interpretation of the schema was that you can provide the records in whatever
format you wish, it could conform to the DC schema as outlined in the OAI 1.1
spec, or you could specify your own.  The OAI 1.1 only specified that you must
provide an instance of your data using the DC schema.

Our system provides records in DC as per the schema for general consumption or
using our own VEMS standard, which provides the same information but with more
descriptive detail as to what things are.  The ListMetadataFormats verb provides
a list of the schemas that the repository can provide the data in.

Subject: [OAI-implementers] XML records and RDF

I was looking at the feasibility of putting up a collection of
records using a scheme which is an extension of Dublin Core. However,
they have encoded the records using RDF rather than the simpler
OAI schema as used for Dublin Core records. (ie: lots of
<rdf:description> and <rdf:value> elements all over the place.)

The DC records included in appendex of the OAI 1.1 spec however
does not use RDF.

Just wondering if there was any reason for me not to return my
records using the RDF based schema? I could try and convert them
to the OAI DC schema as well (so available in both formats).
Just wondering if there was any wisdom here. (Eg: "we chose not
to use RDF based DC XML because...").

I am not an RDF expert by the way, so don't understand all the
subtlties that may be involved.

Alan
