HI, I think if we see the request for a feature which has a coverage-valued property as a need for service composition with one fronting the other - but without a clear semantic difference in their roles - then we are saying really that the WCS is a specialization of WFS (I would argue this is true also for SOS - I know Simon sees it the other way around) - the proposed service chaining is then more a migration strategy than things as they should be.

The core-extension spec pattern dialogue has bothered me in some sense in that there is a more fundamental issue in the standards work of the OGC - there is no foundation model or architecture that describes how the various OGC specs fit together in a consistent and logical manner. This includes not having a consistent information model. I believe that you have put your finger on exactly the same issue except that you have also gone one step farther and provided an initial reference model for discussion. I believe until we can agree on such a model (architecture?), we will continue to be plagued with a variety of semantic issues, inconsistencies in our specs, confusion in the market as to how they all fit together, and so forth. Let's definitely keep this discussion going! Regards Carl
