CETIS have launched a Wiki to cover Educational aspects of Metadata.
This Metadata FAQ has been developed collaboratively during 2004 by participants from the Dublin Core Metadata Initiative, the IMS Global Learning Consortium, the IEEE Learning Technology Standards Committee and other organisations including CanCore, ADL, JES and Co and CETIS. This FAQ provides guidelines and information and has no official status within any of these organisations. The intention is to continue this work and encourage participation from the wider community with the assistance of a Wiki hosted by CETIS.
At present, there aren’t too many entries, but they seem to be useful – of course, like all these community things, they need to be used.
