define wms content by getCapabilities response

[kaestli]

Rather than defining the web service to retrieve different layers (wms request=getMap), I'd suggest to provide / expect metadata describing the request=getCapabilities service; that service does not only provide the list of layers available, but also extended metadata on these layers (e.g. layer-specific projection lists, abstracts etc.)
Further, the layer list would be dynamic, not requiring the change of dcat metadata if layers are added/removed.
(improvement, actually not of the dcat definition but of the way how it is used, and of the depending applications)
