SRU Record Schemas

The table below lists schemas in which records may be transferred. The list is not exhaustive. None are required to be supported, and any other schema (whether on the list below or not) may be supported in addition.

The Explain document lists the XML schemas for a given database in which records may be transferred. Every schemas is unambiguously identified by a URI and a server may assign a short name, which may or may not be the same as the short name listed in the table below (and may differ from the short name that another server assigns).

  • If you wish to have an identifier listed here, then please contact the SRU Maintenance Agency.
