Summary
PlanetDR is an open source Content repository developed under the umbrella of the
spanish research project PLANET (Augmented Collaborative Plataform for content distribution
and advanced training).
PlanetDR supports standards such as IEEE LOM, IMS Content
Packaging (IMS CP), IMS DRI (EduSource Communication Language-ECL) and
LORI SQI. PlanetDR also provides a federation mode between PlanetDR
servers and plans to support the FIRE protocol. PlanetDR is developed in the
Java language, using Apache Tomcat, MySQL and AXIS.
The ECL functions implemented by the PlanetDR's
web services consist of search service, submit service and request
service. There are different types of search, first, the quick search,
that allows to ask for contents that verify in any field of the
associated meta-data the wished word. The advanced search consists of
two types: search by main meta-data category, where any field of a LOM
meta-data category could be specified. The second type is accumulated
search, that allows to make search on any field, linking together
conditions of different LOM categories. It is possible to invoke the
web services provided by the URV, or the web services implemented by
any active content servers. It is also possible to invoque a feredated
search, (a simulated gather service) linking together the results of
the requests of all the active content servers.
We are developing an advanced federated architecture that seamless interconnects content
repositories. We follow a SOA (Service Oriented Architecture) based approach using a UDDI
Repository Registry,
an efficient communication channel and advanced replication techniques.
We take part in the PROLEARN Network of Excellence.
Learning resources provided:
-
PlanetDR focuses on providing open source software for content repositories and not as a
Repository service. Nevertheless, services such as MOREA
are PlanetDR and they offer learning contents in spanish and
galego.
- Decentralized UDDI repository and SOA inter-server architecture specifications support.
Work in progress...
