Abstract

Many RDF repositories have already been implemented with various access languages and mechanisms. The aim of the EDUTELLA framework is to allow communication between different RDF repository implementations. Part of EDUTELLA is a Query Exchange Language (QEL) which can be used as lingua franca to retrieve information from RDF repositories. This work shows why we also need standardization of distributed modification capabilities. We describe use case scenarios for annotation and replication services and use them as guideline for our approach towards a Modification Exchange Language (MEL) for distributed RDF repositories.

Keywords

Query Language Primary Copy Learning Management System Replication Protocol Collaborative Annotation 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
