Hello, I'm working on semantic extension for XWiki[1][2] and currently on performance tunning to be ready for scaling up. The problem with current implementation is that it always modifies semantics DB on all page views. E.g. when I do have a page with {{semProp value="http://purl.org/dc/elements/1.1/title::The Hobbit"/}} to define property 'title' to value 'The Hobbit', this macro basically saves this knowledge to the DB everytime the page is viewed which is obvious performance killer. Of course there is a possibility to optimize this call to first check if the property is already defined and if not, do nothing, but it's still not the best. What I think I'd like to do is to kind of check if the pages is saved or viewed and based on this semProp will do its job (during page save) or will do nothing (during page view). Now, my question is if something like that is possible since I've not found any hints about it so far. Thanks!
