*Discussion*
Jim gave an update on a Moving Images Collection (MIC) project call last week. The schema is pretty much set and is available from the MIC website at: http://gondolin.rutgers.edu/MIC/
Right now Grace has a spreadsheet with all the attributes and descriptions but the schema needs to be formally documented and a white paper written. The plan is to have a prototype directory up and running in June. There is an AMIA conference in early June where paper descriptions of video collections will be requested from participants. The descriptions will then be keyed in since the web input page is not up yet.

Two topics were raised at the Internet2 Spring Member Meeting. Doug Pearson is considering a survey to document meta-data that is now being incorporated into video cameras. Some of the new high definition cameras captures MPEG-2, create proxies in lower resolution MPEG-4, creates key frames, have GPS systems for camera positions, and automatically record lens settings. An automation meta-data stream is generated for playback on a camera. There are some consumer digital cameras that record in MPEG-4 or Windows Media MPEG-4 and capture some kind of meta-data. Jim will follow up with Doug.

Jesus Salillas of Prous Science Barcelona introduced the second topic. They're expanding their phonetic search to include object recognition using MPEG-7 objects. He's looking for a forum to come forward with a standard set of MPEG-7 attributes that could be used for search systems. Grace thought it might be interesting to apply their search engine to someone's sample database from the MIC project. The database exports into very clean XML and MPEG-7.

The DRM efforts in Internet2 are still in an intermediate state. It may be possible to bring them into VoD. Jim has contacted Magda Mourad with the IEEE Learning Technology Standards Committee (LTSC) working group with information about this group's efforts and about possibly collaborating with Internet2. He hasn't heard back from her yet. Research Channel has recently joined the Internet Streaming Media Alliance, which has a working group on DRM as well. They're taking a base level approach on defining the model that includes the encryption of a data stream, authentication and simple authorization. They have drafted a paper and recently polled for a title for the specification and are getting close to publishing. Jim expressed concern that if Internet2 waits too long, a specification may get drafted outside our input.

Grace requested that people be on the lookout for possible collections to use the MPEG-7 application with once the application profile is up on the website. It has a lot of different fields and is pretty complete. It would be nice to promote it to generate some interest among the community now there is a tool they can use to explore MPEG-7. The profile will be linked from the Internet2 site, and information mailed out to relevant groups to let them know about.

The next call will be Wednesday June 4, 2003.
