Agrega is a SCORM 2004 learning object repository network with the LOM-ES profile, with nodes distributed throughout all of Spain’s Autonomous Regions. Each repository offers a set of services for managing the objects it stores. From the point of view of interoperability, the project had two basic objectives: one was to create a modularised functionality that could be reused by other external applications and the other was to be able to interoperate with other external digital repositories. The first objective has been met by implementing a web service architecture used by the nodes and any external application that wishes to integrate with Agrega; in order to meet the second objective, it has been decided to implement IMS DRI and SQI standards, which guarantee interoperability between repositories. This article describes the infrastructure for web service interoperability and standards that have been implemented.
