  Ingestion request: Generation challenges at INLG 2022
  This is to complete the ingestions of all papers from INLG; the Generation Challenges papers still needed to be uploaded. See #1897 for the other papers. 
  
  Here are the papers and metadata from the INLG generation challenges, as generated using ACLPUB2: https://drive.google.com/file/d/1518aAVuvtbvHgw_6FREzJl0kip_lkqNg/view?usp=share_link
  
  I think this matches the Anthology format, but I'm not sure as I added everything manually. (Export didn't work.) Could you check whether everything is OK to ingest in the Anthology? Many thanks!
