I'm on the verge of being able to do what I want, but not quite there. Perhaps someone can push me over the edge? I have templates one of which looks like this: {{Web citation |web link= |title= |author= |date=Month dd, YYYY |source= |wesay= |extract=}} I can call this template a number of times on any given page and list a number of links to articles all over the web. When the template presents its output it makes variables like {{{author}}} and {{{source}}} into internal wiki links. Let's say we have: source=New York Times and that appears in many calls to this template from many pages. On the summary page that I will have for the New York Times, I'd love to have a list of all the titles and links to the articles for the NYT that I quote from across the wiki (even if they are on pages that contain other article links to other sources). I'm playing with both the Semantic Media extension and the DPL. With DPL I can get a list of all pages that contain some link to the NYT. I can even (through use of the template feature) get access to the other parts of the template calls to get at the {{{title}}} and {{{web link}}} parameters. The problem is this query will always give me all the OTHER articles referenced on those pages, even if they aren't for the NYT. I've not worked out if Semantic can help me yet on this either. It seems to be about categorising whole pages as well. If you've got this far and are interested in helping me, well done! I am close to having something of quite general use, but I'm not there yet.
