There is some work done so far that we could use in the near future:
Alfanet.The people of Alfanet have already done some integration of IMS-LD and OpenACS which is published in the Alanet project page. We couldn't do any reuse of the resources dough, because at the time of developing the package we didn't have access to the code.
LAMS. At the time of writing this specification, we were planing to do an integration with LAMS, which is a tool for designing, managing and delivering online collaborative learning activities. The LAMs project is already integrated with Moodle. We can take advantage of that integration experience, but we expect to write all the code at .LRN from scratch, and maybe later work on the integration.
RELOAD. It has an IMS-LD editor which is independent from any LMS. By means of this editor, you can generate an IMS-LD for a concrete course. Also it has integrated the CopperCore player
CopperCore. It has an IMS-LD editor which is independent from any LMS. By means of this editor, you can generate an IMS-LD for a concrete course. Also it has a player.
Our purpose is to be able to interpret the IMS-LD generated by RELOAD, CopperCore and LAMS and whichever IMS-LD that can be generated by other different authoring tools.
