OMG, as usual, you're completely correct. More correct than you might think, so I guess it's time to spring a little secret: [[Special:Relations|Relations]] can work both ways ie the [[Relation:Inverse|Inverse]] of each other. For example, [[Relation:Capital Of]] is the inverse of [[Relation:Has Capital]], and vice versa.

So far, we haven't really pursued two-way relations because they can be somewhat redundant. Besides, [[Centiare:ASK]] queries can be run at the  '''''target''''' pages to produce, in effect, a mirror entry. One-way relations work great when we have a pyramid structure, like [[Relation:Page Of]] for your books @ [[Directory:KJ Kitchens|KJ Kitchens]] or political subdivisions like [[Relation:State Located In]] at [[Directory:California|California]].

For movies however, we have equal weight between people & movies, so we do need two-way relations like ''Actor In'' at an actor's page and ''Has Actor'' at the movie page. If we don't use inverse relations, then one would need to run an ASK query at either location to get all other relations to that page, BUT they would be dependent on all the information being there. Make sense?

So, IMHO, here's what needs to happen: I went through IMDB and listed all the respective info sections they have for both people & movies. Before I go and create a bunch of semantic tags, I need both of you to understand the technical issues (described above) & get on board with their utilization. I've listed them at [[Centiare:Entertainment Annotation]] in the same order as they appear at IMDB for us to discuss. [[User:Snerfling|Snerfling]] 14:18, 14 February 2007 (PST)
