OE-APDocumentation: Organic.Edunet AP Documentation

The intent of this page is to document the Annotation Profile created for the Organic Edunet project

In the project a LOM-profile in RDF is used with the draft-binding created by Mikael Nilsson here: http://dublincore.org/educationwiki/DCMIIEEELTSCTaskforce_2fLomDCAMAnalysis . Along with this the terms and vocabulary is defined here http://dublincore.org/educationwiki/DCMIIEEELTSCTaskforce/LomVocabs and here http://dublincore.org/educationwiki/DCMIIEEELTSCTaskforce/LomTerms

After the Annotation Profile was created, a new draft was created and can be found here: http://dublincore.org/educationwiki/DCMIIEEELTSCTaskforce?action=AttachFile&do=get&target=LOM-DCAM-newdraft.pdf Some changes have been done in this document that affects the Annotation Profile (TODO: Find all changes)
