The Moving Images Collection (MIC) project is building a video directory infrastructure and a video asset union catalog that will be run by the Library of Congress. The project website is at: http://gondolin.rutgers.edu/MIC/. The goal is to provide an interface for access to moving images collections. The archive directory is LDAP and the Union catalog is a combination of MARC and MPEG-7. There will be separate portals based on interests such as: research, students, archivists, etc. They plan to do Shibboleth development over the next nine months to enhance access controls To create a directory listing there are 96 elements and it takes about an hour to complete. The server caches it, so if you're interrupted, data entry picks up where you left off. Not all images archived and listed will be universally accessible since some AMIA members want footage recorded /cataloged but not listed or accessible.

Are there similar issues in the R&E space? Yes. Presidential libraries, research in progress, or other collections that have time restricted access. How does the concept of virtual organization translate to group editing? Are there clearly defined roles to delegate and assign? They are currently of interest and under discussion. There are organizations that want control over the tree and the ability to pass individuals in for access based on affiliation with a particular organization. Internet2 would like to document a use case. Greg Lukow and Barbara Humphries would be the people at the Library of Congress to involve.

Research Channel is starting to look at other metadata schemas targeted at broadcast to lay a foundation for intellectual property protection. They will deploy the PBS created schema called PBCore. PBCore schema is directed more for broadcast and what the state of the footage is, raw, edited, ready to air, etc. A project is underway with a number of PBS stations in the Midwest using the schema. The goal is to build a large collection of ready to air content that these stations can share. One reason the project is interested in Shibboleth is because PBS stations are often tightly affiliated with campuses so trust is a part of the equation. For stations that are completely separate the question may not come up as naturally.

The next step is DRM and intellectual property management. After Shibboleth is incorporated into MIC there may be interest in moving forward on a proposal from last year for a federated digital rights system based on Shibboleth.

Ken Klingenstein has been talking to the Mellon foundation about fair use tools, and how the tool could be packaged with the content in a tight binding. There will be discussion of this in conjunction with the next CNI task force Portland.

Fedora has the ability to tag a content set with behavior object so if you're authorized to interact with you receive the appropriate methodologies to do so. They haven't done anything for streaming media yet. They're interested in partnering with someone with a lot of content to build an interface.

Internet streaming media alliance (ISMA) U. Washington is a member and Research Channel is a liaison partner with ISMA. They are interested in streaming and end-to-end issues. MPEG-4 has some DRM capability, and hooks into a video stream. They're interested in how the interaction happens between a streaming server and client in how it obtains keys, decodes, authorizes, and authenticates. http://www.isma.tv/home

IEEE learning technology standards committee (LTSC) just went through gathering requirements for rights management. The committee has a few universities members but is mostly publishers and vendors. More input from universities to the group would be good. http://ltsc.ieee.org/

Egon Verharen of SURFnet recommended that an overview and analysis of all the different projects to determine the best approaches would be extremely useful. There are a lot of data models with similar purposes and it would be very helpful to document, what are they used for, good for, and not good for. Ken stated that someone could be commissioned to gather information about meta-data schema and do comparisons if the VoD group would provide the categories and comparison criteria.

One thing from the MIC and PBS projects is an awareness of all these schema efforts and the need for mapping. Rutgers has built a tool that you enter content in MIC mpeg 7 or in MARC and it will translate between the two and expose it in XML as well. The next phase will be to incorporate PBCore into that tool.

There is increasing co-ordination between the UK, Australia, and the U.S. in these development areas. Helen Hockx-Yu of JISC indicated they want to look at metadata and the integration of streaming media/moving images. They are very interested in exchanging information on projects and efforts with VoD. Jim indicated that a project status page could be added to the VidMid VoD web site.

Helen indicated that they have funded digital library projects to look at possible mapping and metadata schema registries where people designing a new system could go to the registry and see what's already been developed. They are very interested in what others are working on in this space.

Ken suggested that role based access control may be where the VoD focuses next and it could be combined with Fedora and related to the AMIA work. It's a logical step since teachers ought to be able to do things with content that students can't. There was general agreement that this is a good area to focus on.

It was also agreed that arranging a call with as many interested parties as possible to share information on the projects they're working and aware of would be worthwhile. Discussions can start initially via the list and e-mail.

[AI] Jim will send e-mail to the list and other interested parties.
