[cat-interop] CSW APISO ServiceTypes

[Signell, Richard]

Catalog Interoperability folks,

As part of a system test for the Integrated Ocean Observing System,
we've been trying CSW apiso queries to different endpoints and trying
to retrieve specific service types from the retrieved records (e.g.
WMS, WCS, OPeNDAP).  This has been revealing, but not that surprising
-- different endpoints represent the services differently.

As an example, two geoportal servers (at NODC and NGDC) I've been
working with have:

WMS:

urn:x-esri:specification:ServiceType:wms:url
urn:x-esri:specification:ServiceType:WMS

OPeNDAP:

 "urn:x-esri:specification:ServiceType:odp:url"
 "urn:x-esri:specification:ServiceType:OPeNDAP"

The providers at NODC and NGDC are both willing to change, and would
be happy to use a "standardized" representation -- if only they knew
what it was!

Have folks on this list worked on this issue yet?

Thanks,
Rich
