Dear Bernhard, Thanks for having sent your use cases and starting up this thread as I have encouraged you last week. It seems to me that your use cases are pretty similar to the ones described in our Use Cases document, in particular at http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-reqs/#uc4 Would you agree with this? This shows at least that your questions are really relevant. I do have one question regarding your second use case: > - Scenario 2: Spatial and Temporal Annotation of Videos with complex > region-shapes > > Bernhard selects a video sequence (start-& end-point) in an online > video and creates a new annotation for that sequence. He draws an > ellipse around a specific region in a frame in order to identify the > spatial dimension of his annotation. Then he writes a note for this > region. The system exposes his annotation as an RDF document, where > the annotated map region is identified by a media fragment URI. In this use case, would you need to address a fixed spatial region over a period of time? Or would you need to address a moving region? More comments to follow ... Best regards.
