Hi Matt,

Thanks for posting.

We've got a good start in our Discovery listings now:
# of OpenSearch services: 5
# of DataCasting services: 3
# of ServiceCasting services: 1
# of various Discovery clients: 10

Your client_id approach to track metrics is interesting. It brings up a fascinating look at the variety of REST Request parameters used, as well as the variety of different formats used for OSDDs:

It might be good for the Cluster to begin work on standardizing something on this front...

Recreating a reply since I wasn't on the list when this message was initially sent:

I have updated the wiki with information regarding our ECHO-ESIP API and sample Html client.

>(2) Have there been any improvements to data and service discovery/access?

Not sure if it's what you're looking for, but the attached document contains a brief overview regarding our ECHO-ESIP API's ability to generate dynamic OSDDs.  We needed this in order to embed a client_id for metrics, but did not want to force the introduction of a required request parameter.
