[gt-user] GT 4.0 and MDS

[Mike Jackson]

Hi folks,
I've been using MDS registration and have written my MDS registration file 
below. It works fine and I can see the resource property values when I query 
the index service.

Is there a way for me to provide arbitrary content in the MDS registration file 
that is exposed? From the wording of some user doc I suspected I'd be able to 
use:

    <agg:AggregatorData/>

e.g.

    <agg:AggregatorData xsi:type="agg:AggregatorData">
      <myMetaData>This is my meta-data</myMetaData>
    </agg:AggregatorData>

But this didn't work. And I've since found other doc that explained the role of 
AggregatorData in more detail (and which said I was barking up the wrong tree).

So is there a way of exposing an arbitrary chunk of XML provided in the 
registration file, via the index service? Or must it be done via a resource 
property.

Any suggestions?

Thanks,

mike
