(2006-08-24) Udell Tag Query

Jon Udell on the need to move Tagsonomy querying a bit beyond Del.icio.us without going as far as DabbleDB. Consider how DBase and later MsAccess were overkill for most people's recipe lists and Address Book-s, and how 1-2-3 and Excel wound up meeting the need instead. Tag systems might turn out to be the Spreadsheet-s of modern information management. If you buy that notion, here are a couple of next steps. First beef up the query language with support for term negation, along with string, numeric, and date comparison. Second, enable privacy along the tag axis as well.
