In the FIRE federation, each query language and results format is identified by the namespace of its schema (in red below). The default values are underlined.

Query Languages

• LRE Query Language (LRE-QL, namespace=http://www.prolearn-project.org/PLQL/l2).

Result Formats

• Strict LRE LOM resultsset (namespace=http://fire.eun.org/xsd/strictLreResults-1.0): strictLreResults-1.0.xsd.
• Number of metadata records matching a query (namespace=http://www.prolearn-project.org/PLRF/0/lom).

More information about how to use LRE-QL and the associated result formats can be found in "LRE-QL: Introducing an LRE Context Set For The Federated Discovery of Learning Resources".
