[Esip-discovery] ESIP Discovery Cluster Telecon, Tuesday, Aug. 9 @ 4:00 ET / 3:00 CT / 2:00 MT / 1:00 PT

[Eric Rozell]

James,

We had discussed that adding a new attribute to Atom would cause the W3C feed validator to crash, unless that attribute used a namespace.

I think the proposal is to use the ESIP namespace for new attributes that could be used in the discovery protocol. Particularly, given the "two-level" aspect of the discovery protocol, the rel attribute would be used for "generic" information (e.g., http://esipfed.org/ns/discovery/1.1/data#) and a new attribute would be coined for web service "specific" information (e.g., http://xml.opendap.org/ns/DAP/3.3#).  Both the namespace and the actual name of the attribute are up for debate, but an example might be:

<link rel="http://esipfed.org/ns/discovery/1.1/data#" xmlns:esip="http://esipfed.org/ns/discovery/1.1/" esip:spec="http://xml.opendap.org/ns/DAP/3.3#" href="http://disc2.nascom.nasa.gov/opendap/TRMM_3Hourly_3B42/2011/001/3B42.110101.12.6A.HDF.Z" />

I've added some of this information to the Talk page for DCP-2.

-Eric
