Hello, Apologies if this has been asked before, or if there's a more appropriate forum. I've been hunting but not found anything yet on mediawiki, Wikipedia, or the discussion list archive. Tried wikitext-l first but not sure anybody's on that list anymore.

Is it possible to parse or call the data from template A on page X, and spit parts of it back out using another template (say, template B) on page Y, and in a different namespace? For the sake of argument, assume there is only one template A iteration on page X.

For example,

Template A {{bookdata | image = no | title = A big long title | maplink = Image:Title_p82.gif }}

Template B

{{mapdata | title = [calls 'title' value from bookdata] }}

It seems like there should be a way to do this, so if it means reading manuals on something I'd be happy to. At this point I'm just not sure which direction I should be going to read up on this.

Thanks for any advice.

Craig
