I think that is more important to have a standard for creating and updating
"virtual" topic maps. From logical perspective TMQL can work with one
"virtual" map. But we need a standard to define what "virtual" TM is, what
TM update means, how we can cache topic maps, how we can "subscribe" to TM
modifications, how modifications can be propagated through TM network. (TM
fragments, TM Diff?)



Kind of "Distributed SAM".
