To be fair, though, you asked about DCMI or OAI markup inside <xenoData>. The only time I have used <xenoData> I tucked some MARCXML or MODS info in there. But it was not a “real project” so much as an experiment for one, and there are no vestiges of that experiment left on my disk, it seems. The WWP used to have a flat database of “reception items” (i.e., reviews) of works in our textbase. That metadata was extracted from the flat database for all files, and is now stored in a <xenoData> in each individual file. The format used inside <xenoData> is just a single xqj:json element which holds a series of name-value pairs. (See Women Writers in Reviewhttps://www.wwp.neu.edu/review/ for the front-end.) ________________________________ a few weeks ago i posted a query about usage of xenoData on tei-l and followed it up with a repeat on twitter. i was a bit surprised to receive absolutely zero response (full disclosure : i did get a reply from m.mueller but not to the question i asked) . so either no one is using this lovely tag or no one wants to admit to it. either of which seems somewhat of a problem. maybe, i thought, maybe the mandarins of the tei council know better? are any of you using it for real in a project?do you know any project which is?
