We have a requirement to get the list of items which are tagged with a specific tag (folksonomy) accross the application which contains many site collection, sub sites and my sites. Is there a OOTB feature to achieve this?
If not, can you suggest some approaches to achieve this? I was thinking to run a timer job that goes through the items and checks the tagged item and maintains data in probably a custom DB. I am not sure whether sharepoint change log can provide the list of items in case items have been updated with tags.
Thanks in advance,
Bidyut.
