Hi there, I'm trying to figure out the best way to implements a general solution for tags (like tags on flickr or del.icio.us). So far I've two different approaches, maybe someone could comment on them:
1) Store the tags as attributes of the particular content types. Searching for tagged content is handled by a catalog index. New tags are created by simply adding them to the object, a collection of tags is the set of all tags from the catalog. Drawbacks: centralized tag management is inefficient, e.g. deleting a tag implies searching for the particular tag and removing it from all objects it was tagged with. 2) Store tags in a local utility. The utility manages a tag -> intids mapping (similar to a catalog index). Searching for tags is easy - just query the mapping for appropriate keys. New tags are created by adding a new key to the mapping, a (weighted) collection of tags is the list if mapping keys. Drawbacks: I can't think of any right now Has anyone done that before? Maybe I'm just reinventing the wheel...
