I hope this is the right place for my question.
I work for a data repository. In the past, data depositors have asked us to archive and publish Twitter-related data, i.e. especially Tweet-Ids. I cannot find explicit/comprehensive policies about how (and if) Twitter allows Tweet-Ids to be shared by repositories. In particular, I wonder whether
a) Twitter has a limit about how many Tweet-Ids may be shared. Please note that I am talking about Ids, not tweets. Thus, Twitter API is always needed to access the tweets and rate limits for API automatically apply.
b) Twitter has policies that allow/disallow extracting information from tweets such as hashtags and sharing those via data repositories directly (not via Tweet-Id).
Thank you very much for your help in advance!
