Currently the bot only proposes one parameter change at a time and doesn't support access level parameters such as doi-access=free.
When we add a handle, the edit is less useful than it could be because the identifier is not marked as open access:
{"utcnow": "2019-07-17 15:03:05.652772", "page_name": "CEBPD", "proposed_edits": [{"conflicting_value": "", "orig_hash": "bdb0b230d5d0ab4937afb0feb43cb90c", "proposed_change": "hdl=11382/3170", "classification": "link_added", "index": 18, "policy": {"romeo_id": "2823", "preprint": "can", "postprint": "can", "published": "cannot"}, "orig_string": "{{cite journal | vauthors = Angeloni D, Lee JD, Johnson BE, Teh BT, Dean M, Lerman MI, Sterneck E | title = C306A single nucleotide polymorphism in the human CEBPD gene that maps at 8p11.1-p11.2 | journal = Molecular and Cellular Probes | volume = 15 | issue = 6 | pages = 395\u20137 | date = Dec 2001 | pmid = 11851384 | doi = 10.1006/mcpr.2001.0377 }}", "issn": "0890-8508", "proposed_link": "http://hdl.handle.net/11382/3170"}]}There are currently only 300 usages of hdl-access, which in turn weakens current proposals to use such parameters to determine the title link and so on.
I suggest that we start by 1) making it possible to edit two parameters at a time, 2) setting the hdl-access parameter. Later we could also 3) set doi-access depending on what Unpaywall tells us and 4) (given that's going to be hundreds of thousands of changes) ask a bot approval to chance such parameters (which are merely informational and therefore unproblematic), per T195441.
