Hello, Yes, I think I can propose one or two use cases. I will try to add something soon. Frankly, I have only a very general use case in mind: Getting geospatial data to work on the WWW. And I see some worrying gaps in the current specifications for that. But I will try to word this use case in such a way that I hope it will be compatible with other use cases. As for the place of use cases in the structure of the wiki: How about creating a separate page for each use case? In general, it seems a good idea to me to make separate pages for separate things. That should give us a nice amount of freedom in interlinking those pages and creating summary pages or tables of content. With this approach we could also postpone having to have an obligatory format for use cases. The same could go for the specifications we like to describe or evaluate: they could be on separate pages too.
