cool stuff richard. so how do/should we expose GUIDs to the outside world, in a sorta "Web" kind of way? cause it's not enough to just generate unique IDs internally, we also have to "broadcast" their, um, "meaning" to the world at large...
in other words, seems like you need the ID, some metadata to describe the thing ID'd, and a publishing/broadcasting mechanism so that other people/systems know you have info to communicate. a la: http://musicbrainz.org/artist/ba853904-ae25-4ebb-89d6-c44cfbd71bd2.html sounds like the Web to me... and MusicBrainz, for instance, is an example of all of the above, no? but now, don't we need an EverythingBrainz (as a colleague of mine recently put it)? (BTW, i'm a person that feels that URLs, by definition, are GUIDs) best-- --cs -----Original Message----- From: [EMAIL PROTECTED] on behalf of Richard Cartwright Sent: Tue 3/4/2008 5:31 PM To: BBC Backstage Subject: Re: [backstage] What would you love to see coming out of BBC Vision in the near future? Chris I¹ve a lot of recent experience with 16-byte UUIDs for identifying content (RFC 4122) and the slightly more media-savy 32-byte Unique Material Identification (UMID) from SMPTE (SMPTE 330M). Both standards are the basis for the Advanced Authoring Format, an industry standard used by video production tools from companies such as Avid and Quantel, and the related Material Exchange Format (MXF) used for production material interchange and now supported by a number of broadcast quality cameras, transcoders etc.. UUIDs are also known as GUIDs and are common to Microsoft Windows OS. Many unix OSs have a ³uuidgen² command to create UUIDs. Java has a ³java.util.UUID² class for generating and representing UUIDs. UUIDs are very well supported and have been the subject of some interesting security issues as without careful use they can expose your host ids outside your network. I am working on a media-specific Java API for AAF and MXF that includes support for UUIDs and UMIDs. Both can be generated at source and, as long as a consistent generation strategy is used, should be globally unique.
