Hi @mr-martian, thanks for the PR and sorry for the late response!

The code changes as they are actually won't be sufficient to implement this--there are other places in the code that need to change in order to accommodate DEPREL service outputs. These are, at least:

• ::anno-type
• calculate-stats
• sort-map
• document-query

I'd work on this myself but I have higher priorities ATM so I'm not sure when I'll be able to get to it. If you'd like to keep working on implementing this, it ought to be pretty straightforward to copy and adapt what's already there for other fields, though that may be difficult depending on your familiarity with Clojure. Please let me know if there's anything else I can tell you.

well, there's an attempt. I'll see about testing it properly maybe tomorrow.

sorry this has been sitting for so long! those changes look right but I'll need to take a closer look with the code running, hopefully next week
