Hi Charles,

Thanks - the doc was useful.

There are some tools that are designed to let you publish whatever you want, so long as it is properly formatted XML. See if http://www.globus.org/toolkit/docs/4.0/info/aggregator/Execution_Aggregator_Source.html walks you through the process explicitly enough.

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
