Records

According to OAI-PMH, each record must have an identifier, but this identifier cannot be a URI. As a result, the CHO URI provided by partner institutions cannot stand in as the record identifier in the OAI. In order to create a consistent and stable identifier, the CHO URI is encrypted by MD5 into an alphanumeric string of characters. This hash forms the basis of the http://harvester.orbiscascade.org/record/ namespace and is also used within the record identifier in OAI-PMH. The record URI is used as the URI for the ore:Aggregation of an object. This makes it possible to render or delete a single record.

Examples:

• http://harvester.orbiscascade.org/record/6c94990ae7292a167fa67b4142f22dc4
• http://harvester.orbiscascade.org/oai-pmh/?verb=GetRecord&identifier=oai:harvester.orbiscascade.org:6c94990ae7292a167fa67b4142f22dc4&metadataPrefix=oai_dc
