【 摘 要 】

In order to achieve interoperability among learning repositories,implementers require a common communication framework forquerying. This paper proposes a set of methods referred to asSimple Query Interface (SQI) as a universal interoperability layerfor educational networks. The methods proposed can be used by asource for configuring and submitting queries to a target systemand retrieving results from it. The SQI interface can beimplemented in a synchronous or an asynchronous manner. SQIabstracts from query languages and metadata schemas. SQI hasbeen evaluated by several prototype implementationsdemonstrating its universal applicability, and is on the way tobeing standardized in the CEN/ISSS Learning TechnologiesWorkshop. The latest developments of SQI can be followed athttp://www.prolearn-project.org/lori/.
