Get All Topology Info

So say we wanted to get all the (meta)data from the LS which corresponds to Topology information, we should send the following XQuery:

Link Status

This is how we query for all the link status:

Code Block

        declare namespace nmwg="http://ggf.org/ns/nmwg/base/2.0/";
        /nmwg:store/nmwg:data[child::nmwg:metadata/nmwg:eventType='http://ggf.org/ns/nmwg/characteristic/link/status/20070809']

Which basically tells the LS to return all nmwg::data elements that have (nested) child eventType of the link status as defined. This returns:

Querying for Services

So say we just want to find out where to get MA information from, we can do a direct query for the services that are registered with the following xquery:

Code Block

        declare namespace nmwg="http://ggf.org/ns/nmwg/base/2.0/";
        declare namespace perfsonar="http://ggf.org/ns/nmwg/tools/org/perfsonar/1.0/";
        declare namespace psservice="http://ggf.org/ns/nmwg/tools/org/perfsonar/service/1.0/";
        /nmwg:store/nmwg:metadata/perfsonar:subject[child::psservice:service]

Notice that because of the extra namespaces in the new tags, we have to declare them prior to use.
