Hi,
The way to distinguish services metadata from other metadata is via the
hierachyLevel element. The codeListValue of this element should be
"service". You can then look at the protocol element to see what type of
service is available. That is wms, wfs, wcs, etc.
The hierarchyLevel element is mandatory if the hierarchyLevel is *not*
"dataset". Therefore is will be completed if you are describing a "service"
so it is the best element to use to identify the types of metadata records.
I hope that this helps and that I am not repeating what someone else says.
;--)
Thanks.
John

So that could be used to distinguish between data and
services, right?
One could query against the identification section...? I am
not yet very familiar with the iso19139 schema.

I believe, allowing to search for all OWS and also allowing
to narrow that search down to a specific service type would
be a very convenient search option. ServiceType is stored in
Identification/ServiceIdentication/ServiceType/Name, right?
Any pointers on how to make that field queryable via search
GUI most welcome..>Cheers
