There is some work done so far that we could use in the near future:
Alfanet.The people of Alfanet has already done some integration of IMS LD with OpenACS. At the time of writing this specification we were waiting to have access to their code in order to evaluate the possibility to make use of what they have already done, avoiding the waist of resources, but by the moment we don't know if this will be possible.
LAMS. At the time of writing this specification, we were plannig 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, even though we expect to to write all the code at .LRN from scratch instead of doing an integration with an external platform.
RELOAD. It has an IMS LD editor wich 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

Our purporse 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.
