<div>There is a deeper issue here that we should think about as a community.</div>
<div> </div>
<div>Should ontologies be merged or should they be allowed to exist and evolve independently, and be used together through name spacing, an simple upper level ontology, and site specific rules.<br> </div>

<div>My own opinion is that at this point in time it is better to allow independent evolution and diversity and find light and loosely linked approaches to using different ontologies together.</div>
<div> </div></blockquote><div><br>Seeing that Martin has produced/proposed such an elegant extension to GR (i.e. the seeks objectProperty), I suggest that the extension to GR be made. This will cover about 80% of what is offered by TIWAN. The rest is related to discussions (i.e. negotiations) linked to the offering, and these can be tied to GR data using SIOC, thus no further need to modifications. That leaves about 5% of TIWAN unaccounted for, this deals with service specific requests, but I have some ideas of how that can be covered with no mods to GR, please see my reply to Martin's comments for more.<br>
