Eclipse Lyo documentation has moved to its new site under the OSLC Developer Guide, where you can find even more resources for developing OSLC applications.
The documents that remain under this Eclipse Wiki are most likely outdated, or are in the process of being updated for future migration.
If you find information of relevance that needs updating, please open a new topic on the forum.
