Thread:Semantic-mediawiki.org:Community portal/Several related Newbie questions

I've just started looking at Semantic Mediawiki. I'm an experienced Wikipedia editor and also have a lot of experience developing OWL ontologies in Protege. I'm looking at various tools for a project to create a semantic knowledge portal for a set of related topics in cognitive science for a non-profit. We have a budget so I could use a commercial tool, I'm looking at Pool Party and Open Calais as well. I'm pretty technical but more at the level of OWL and logic and editing Wikipedia rather than setting up and configuring servers. I'll have a team to do this eventually but right now I'm in the really early stages of evaluating various tool options so I want to do as much as I can to get a feel for SMW just using the Sandbox. I just wanted to give that as background. So my questions are: 1) How much can I do working in the Sandbox? I noticed some extensions that seem like they would be useful. Especially the extension to create custom forms but I'm sure there are others. The Forms extension is a zip download. Can I download that and use it with my Sandbox or can I only download that (and other extensions) into an environment where I have my own server? 2) I've heard a lot about Dublin Core and it seems like the right model to use for things like books, journal articles, videos, etc. to store all the metadata (authors, date created, publisher, etc.) about them. That seems like such a common possible requirement I was wondering is there any way to load a vocabulary for Dublin Core into my Sandbox environment (or do people recommend a different vocabulary or different way to store such metadata?) 3) As I said I've developed several ontologies in OWL using Protege and also using the Semantic Web Rule Language (SWRL). Ideally, I would like to develop an ontology and import it into my SMW environment. Is that possible? I'm guessing not from my preliminary look it seems like the number of OWL like capabilities that are supported is pretty small. Just inverses, subclasses, but not things like transitive properties, DL definitions for classes much less SWRL rules. It's not a deal killer if this isn't supported but I just wanted to double check to make sure I'm understanding things correctly. But even if I can't take advantage of SWRL I would still like to load OWL ontologies. Again wondering if that can be done with a Sandbox environment or if it requires I set up a server.
