Comment #6 on issue 49 by thost...@gmail.com: Missing information in detailed query? http://code.google.com/p/ogf-nsi-project/issues/detail?id=49 I think the main lack is that in the stpList it is not possible to see which NSA is managing the segment. I.e., a segment from netherlight.ets:ps-83 to netherlight.ets:chi-82, can in theory be managed via the nordunet opennsa. Quite unlikely but possible. Not having this information makes it rather difficult to figure out the actual connection tree. Furthermore there is the question of using URN or URL to reference to NSAs here. We cannot assume that a topology awareness is transitive, meaning that a URN reference such as urn:ogf:network:nsa:netherlight is not known at the querying client. Further we have no idea to tell if the client knows this or not, implying that we would have to use URL everywhere :-/. Personally I saw three types of useful queries: A: The state of the connection. B: All locally available information for the connection (barring any security stuff). This is pretty much QuerySummary + managing NSAs for each segment. C: Complete recursive information. Similar to the current QueryDetails. A of course contained in B and C, and B in C.
