Does anyone know if there is a way to control the keywords that are available when tagging an ArcGIS Online item?
I was scrolling through the keywords available to my organization, and many of them differ simply by capitalization or plural. We're really like to avoid duplicate keywords for search consistency (especially in open data) and avoid replicating typos in the keyword list.
I'm not sure whether your can prevent new tags from being created (don't have access right now to check), but you can use some tools to maybe clean things up a bit. Check out Tools · Esri/ago-admin-wiki Wiki · GitHub
I haven't worked with this yet ArcGIS Item Information but think I will...looks like it has potentially good for viewing and editing tags. I'm away from my office so not able to test this week.
