Stefano,You describe an important aspect of what we have to do in THREDDS-DLESE, that is, create a bond between the two communities. My request for information focused on the discovery/digital library facet and the responses were mainly from those concerned with the geo-information facet.
Your concise summary of the importance of and need to address both facets is very useful.

In my opinion, in the THREDDS-DLESE framework a major task is to bring together two different Information Communities: the Digital Library community and the geospatial Information Community; therefore, we should consider that "objects" like datasets and catalogues (and so on). are often seen from different perspectives. For instance, a Spatial Dataset (or an aggregation of them -according to the granularity level that DLESE prefers ) may be seen according to 2 different points of view: 1) as a digital library resource: at a very high level of abstraction and with no many detail on its content (i.e. high level description and useful keywords); in this context the dataset is a "digital document" (with certain qualifications). 2) as a piece of geo-information: a complex and structured piece of information in a N-dimension reference system. From my point of view, a metadata standard like Dublin Core can be used for describing the first Spatial Dataset facet, while a specific Geo-information metadata standard (i.e. ISO 19915, GDC CSDGM profiles, etc.) should be used for describing the other facet. I don't know how much such solution could be fruitful, but it is an example of an approach for "sharing" information-constucts among the two different Communities. Regards, Stefano Nativi
