We are looking at means to support interoperability between systems in order to support the richest ecosystem for innovation:
We propose to use semantic web and
technologies to describe
annotation of documents
. We are currently studying whether this model is appropriate for dynamic document, or whether we want to expose annotations as markup in that case.
In any case, those annotations will often refer to concepts in concept maps; we will integrate existing semantic vocabularies for concept maps, such as the one used in the Catalyst project
Those concepts will be federated between platforms using Topic maps
User's actions should be exposed as ActivityPub when appropriate, especially in any multi-user context.
