Schema for the description of the provenance of metadata that is re-exposed by the NSDL OAI repository, i.e. metadata that has previously been harvested before being exposed by the repository. This schema is based on the OAI 2.0 provenance schema. See: http://www.openarchives.org/OAI/2.0/guidelines-provenance.htm updated - 2002/09/30 version 1.00.000 updated - 2002/09/24 NRD: corrected local namespaces Updated 2002-09-17 Naomi Dushay: added version attribute to schema, changed targetNamespace, use nsdl_types Naomi Dushay - 2002/06/10 11:00:00 each originDescrption element identifies the provenance of the metadata record, i.e. the chain of originating repositories. The method by which the metadata record was harvested. The location of the originating repository from which the metadata record was harvested. The unique identifier of the item in the originating repository from which the metadata record was disseminated. The datestamp of the metadata record as disseminated by the originating repository. NOTE: granularity of this date as obtained from the originating repository must be preserved. The XML namespace URI of the metadata format of the record harvested from the originating repository. The originDescription block obtained when the record was harvested from the originating repository. A set of nested originDescription blocks will describe proveance over a sequence of harvests. This is optional -- not all records have more than one harvest in their sequence. The date that the metadata record was harvested from the originating repository. In the case of OAI harvests, this will be the responseDate of the OAI-PMH response containing the record. NOTE: granularity of this date as obtained from the originating repository must be preserved. Must be set to true if the metadata record from the originiating repository was altered before being disseminated by THIS repository.
