The problem is that we want to leave out the documents that are NOT hidden, so a query that does that will have to use a subquery (either NOT EXISTS or NOT IN), which increases the query complexity and execution time. And, as Jerome said, we'd have to filter this tag when displaying documents, and, as you said, this setting should not have the same rights as normal tags. > I was going to say: "In general I think we need the ability to add > generic metadata to a document.". however this already exists: it's > called Objects! :) > So I think instead of adding more and more fixed metadata we might > instead want to use Objects.

Mostly query complexity and execution time, but also the fact that for the moment this should be a "private" setting that should not be accessible to normal users. As I said, this is a hack until we'll have the new model in place. The hack is needed because I don't want to use the 'XWiki' space for all support documents (macros, templates, style and others). The extra document metadata field is not such a bad idea IMHO because it is the least intrusive solution. Yes, I know it is the most intrusive one (on the implementation level) because it changes lots of things, but from the users' PoV it is invisible. -- Sergiu Dumitriu http://purl.org/net/sergiu/ _______________________________________________ devs mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/devs
