So do we have a good list of reasons why we cannot use the generic RDFa serialization? Is it because it is un-doable hard? Or is it that the incremental complexity is much greater than the incremental benefit? Is this something that could be solved once, say in the form of an open source library, and then reused everywhere, so the cost/complexity issue is not a problem?I think in a nutshell there was a worry that using RDFa proper--the whole enchilada--would indeed add too much complexity for too little benefit. My sense was the problem was probably less the actually XML parsing code than the UI. If you have complex content marked up with RDFa, what happens when a user edits that content? It seems the primary focus of RDFa is web markup, often hand-authored and relatively static. We really have two choices: 1) keep things as they are, with the expectation we will not augment it later 2) change our attribute names such that our model is a proper RDFa subset and could more easily add more of it later Especially as there is a new draft of RDFa available [1]. One ODF unfamiliar design is the absence of attribute namespaces. I assume the reason for this design, was the expected greater acceptance from the HTML community. Therefore my first question: would we use attributes without namespaces? Second aside of attribute names, there would be still some problem with the attribute data types [2]. For instance @property uses only CURIEs, where we use IRIs.
