Reason for *
change:


The only way catalogues have to distinguish one OGC service instance
from another is by using the service's URL (e.g its base URL or
GetCapabilities URL) which is not a reliable method. So, there needs
to be some other, more robust, way for a catalogue to distinguish one
OGC from another when it harvests them.

OGC Change Request

https://portal.opengeospatial.org/public_ogc/cr_admin.php?CR...

Add a "ServiceInstanceId" field to the service
identification section of the capabilities document. The value of the
ServiceInstanceId shall be a fixed UUID. This way, a catalogue can

distinguish one OGC service instance from another. It is important
that this value be mandatory and that it be universally unique -hence the UUID requirement.

Consequences if It just makes it that much harder for OGC catalogues to harvest OGC
services because they need to implement complex URL comparison
not approved:
functions in order to be able to robustly distinguish one OGC service
instance from another.
