oai_dc schema
-------------
A revised version of the simpledc schema was released on
2002-12-12 and fixes earlier validation problems
<http://dublincore.org/schemas/xmls/simpledc20021212.xsd>.
We have updated the oai_dc schema to import the new simpledc
schema, see <http://www.openarchives.org/OAI/2.0/oai_dc.xsd>.
The previous version is available at
<http://www.openarchives.org/OAI/2.0/oai_dc.2002-06-14.xsd>.
The new oai_dc schema also corrects the unnecessary double
specification of minOccurs and maxOccurs for the individual
elements, i.e.
<complexType name="oai_dcType">
<choice minOccurs="0" maxOccurs="unbounded">
<element ref="dc:title" minOccurs="0" maxOccurs="unbounded"/>
...
has become
<complexType name="oai_dcType">
<choice minOccurs="0" maxOccurs="unbounded">
<element ref="dc:title"/>
...
These fixes will not require any changes to oai_dc metadata but
they will avoid validation errors.
OAI-PMH specification
---------------------
The oai_dc fixes noted above have been incorporated in the OAI-PMH
specification.
The examples in sections 2.5 and 4.5 which use the <provenance>
container have been corrected and now validate against the
provenance schema.
The corrected protocol document replaces the previous version at
<http://www.openarchives.org/OAI/2.0/openarchivesprotocol.htm>.
The previous version is available at
<http://www.openarchives.org/OAI/2.0/openarchivesprotocol.2002-09-13.htm>.
