Hi Raff! Impressive stuff ... thank you again so much for all this work. I tried going to the link, and pretty quickly figured out how to upload an ODD. Using Firefox on a Mac laptop I tried uploading the WWP ODD file, but gave up after about 5 or 10 mins of watching the progress line. I then tried uploading a much smaller, lighter ODD file, and checked in on it every 3 or 5 mins or so. It was done in < 24 mins (but not at 20 mins), which strikes me as a bit too long. I tried uploading the same schema from my desktop at home, and it took ~12 s. Maybe there was some kind of connectivity issue from my laptop (I was using someone else's wireless, and it did seem slow). Anyway, after the ODD was loaded I was immediately confronted with a list of elements (including their glosses and descriptions, which is very nice). There is a wonderful little filter search-box at the top R, which works very fast. I used it to narrow down the field a bit, and have posted a screen-shot.[1] There seem to be elements in three different states: * box on L unselected, X on R * box on L unselected, + on R * box on L selected, + on R I am not entirely sure what the difference is. I bet I can figure it out, but that's not the point. IMHO, there needs to be an on-screen glossary of those 4 icons (L box checked, L box unchecked, R circle +, R circle X). Furthermore, I bet once I know what they mean, I wish I could sort by them. (I'd like to be able to sort by module, too.) I then went to constrain the @n attribute of <ab> "one", "two", "three". I found that "enumerated" was not on the list of available datatypes, and "Manage datatypes" link is just back to the same page. "OK", I figured, "must default to enumerated if I fill in a value list". So I changed the Value to "Closed" (why capitalized?), and tried to figure out how to add "one", "two", and "three". There's a pretty little circled plus sign, but clicking it did not seem to do anything unless I have typed something on the line next to it, in which case what I typed gets erased. (Note: I had also switched it to a required attr at some point.) Thinking that it may have been storing the information in my ODD and just not displaying it, I clicked on DOWNLOAD and selected "Download ODD". Nothing seemed to happen, and nothing showed up in my ~/Downloads/ directory. Hope this helps. Notes ----- [1] https://bauman.zapto.org/~syd/temp/4TEICouncil/RomaJS_add.png
