URL

You specifically says that this is for a landing page and the DCAT implementation readily states this. In the schema approach the ESIP guide specifies this, but are you then restricting the numbers of URL's to 1 that is the landing page? No direct download URL? If you have multiple URL's with different purposes, are these neglected or how do you identify the purpose of a URL (e.g. https://github.com/OSGeo/Cat-Interop/blob/master/LinkPropertyLookupTable.csv)? I see that is challenging with the current status of schema.org.
