This discussion highlights the need for ontology-stores to always keep track of the prevenance of triples. The classic way to do this is reification of triples, of course, but for somewhat inscrutable reasons that fell out of favour almost as soon as it was conceived. In fact most triple-stores are actually quad-stores and already include an extra field which could in principle be used to support this. Not clear that the APIs make it so easy, however. -------------------------------------------------------- Simon Cox European Commission, Joint Research Centre Institute for Environment and Sustainability Spatial Data Infrastructures Unit, TP 262 Via E.

It was never sent as a 'version' of the ontology. It should be seen as an artefact of our discussions on the modelling options, and to the last of my knowledge was only ever available through pages that labelled it as such. I of course agree that examples of the ontologies use and versions of the ontology should be clearly labelled in our wiki pages. There is a version of the ontology that is the result of the groups discussion on measurement capabilities. I hadn't sent it to the group because I wanted to start correctly commenting/annotating/referencing the ontology; however, there hasn't been a decision yet on how to do that. In any event, because of the apparent potential confusion, I have now sent the ontology that includes the results of all our discussion up to and including measurement capabilities. Once there is agreement on how to do it, we can start to build the wiki pages of definitions and explanations and reference this to and from the ontology. I guess issue 7 will be part of this process.
