Felix 2009/7/21 Tobias Bürger <tobias.buerger@sti2.at> > Dear all, > > here is my proposed update of the rationale of r09 ("Taking different roles > in metadata processing into account") with respect to ACTION-141: > > Metadata is generated and being dealt with by different agents with > different roles throughout the whole lifecycle of a media resource. We can > distinguish between producers (e.g., a video camera or the producer of a > media resource), changers (e.g., a person which modifies initially created > metadata), and consumers (e.g., an application which processes metadata to > make it accessible for search). > If values of metadata properties which are, for instance, created my two > different agents, are in conflict, a description of provenance information > with respect to the roles but also the context of metadata creation of these > values could be useful and should be taken into account. For instance, a > manually created value by a human agent might be more reliable than an > automatically created value by a software agent. Furthermore metadata > produced by the creator of a particular media resource might be more > accurate than metadata produced by a media consumer of this resource. > > If you think it is fine, then I can record the change in the use case > document accordingly. > > Best regards, > > Tobias > > -- > _________________________________________________ > Dr. Tobias Bürger > > STI Innsbruck > University of Innsbruck, Austria > http://www.sti-innsbruck.at/ > tobias.buerger@sti2.at > __________________________________________________ > >
