Foldering History: "read" vs. "archived"
For the PL+ project, they are asking for the ability to mark documents in a WebContent feed as "read", thus causing them to no longer appear on their feed. (This is something that we don't do now, but I'm assuming that we could add. It seems like something that would be appropriate to store in History. Correct me if I'm wrong.)
However, PL+ is also asking for a second feature; the ability to mark documents as "archived". Which is similar to "read" in that such a document would no longer appear in their feed, but they would want an easy way to be able to go back to it.
Is something like this possible, the way History is built now? I was thinking that there might be an existing column in the history database that we could use to denote something as "archived" instead of "read", but looking at it I'm not sure such a column exists. (Perhaps EVENT_SUB_TYPE or SUB_CONTENT_TYPE, but obviously we can't break any existing use for those columns.) If not, is it feasible to add one?
Or does anyone think that this is an inappropriate use of history and we'd need to create a separate database somewhere for this purpose?
