Hi Hugh; first off, thanks a bunch for taking the time reading my messages as well as sharing your insights and explanations on that, greatly appreciated! :) Am 12.07.2013 11:55, schrieb Hugh Glaser: [...] > "Document" "belongsTo" "Project" remain as a string.

Well, overally, these two things basically confirm something I have already been pondering. So far, coming from a world of working with either key/value stores or RDBMSs (partially abusing those by again mostly using string data and having most of the rules enforcing consistency kept in business logic - which is a pain more than just once), I am pretty familiar with both using strings and the confusions that mostly will arise from that. So I'll try going down that road getting rid of that confusion as far as possible. > I do realise that this doesn't actually answer your question, as you > are trying model, not transform! But it might help:-) It definitely does. In this situation, boundary between transforming and modeling is rather fuzzy anyway, and though at times I feel comfortable working with OWL and ontologies on a "greenfield", there's a lack of experience in this, and right here with an actually existing (relational or key/value) data set at hand, there's always the danger of falling back to common, convenient patterns of doing things, which might not at all be a good idea. Actually I spent most part of last nite working with SWRL rules in OWL trying to define these things I have in mind as rules inside my OWL ontologies, but the results weren't really the way I wanted them to be. So maybe a better modeling might be a generally better way of resolving this problem. I'll see where it gets me. :) Thanks again and all the best, Kristian
