Posters - Credits, Locations etc

Just trying to feel my way around here. I was looking at my old Posterogs contributions and trying to add more detail but before putting in too much work I thought there should be a conversation as to standardizing credits. Should we stick with Discogs conventions when possible or create something entirely new. Example - Bands listed on a handbill, credited as “Artist” “Performer” or something else? If there is a guest performer do we have the ability to add that as a credit or cover that in notes?

Additionally, on the venue:

  1. to distinguish from venues with the same name in multiple cities do we add the entire address or just city and country?

  2. Is there a master entry for venue? Many times a smaller club may have changed locations over the years or have had slight name changes.

  3. Name changes on larger arenas/ With all the corporate sponsorships these days names change for the same arena happen all the time. How do we link these to one venue?
    Thanks,
