Hi there,
There's an interesting thread on sharing going on @cosmo-dev. On one of
the message, Morgen wrote:
- Tags need to be hierarchical, and when examining an item's Tags for
their ACLs, super-Tags must also be examined.
My gut reaction to hierarchical tag is "no way": hierarchies have plenty
of usability issues (to create, maintain, modify, etc...). The success
of the informal "folksonomies" using tags only is a tribute to the idea
that non-hierarchical tags are easier to manage. *But*, saying that
there is no spelled out hierarchies between the tags does not mean that
there is no structure between them. Such a structure will need to be
deduced through how the tagged items relate to each other. Segmentation
techniques should be able to infer a local hierarchy of tags even in the
most tangled set. Once the local hierarchy is deduced (and appropriately
displayed), one can imagine to turn "off" a whole node ("work" in the
example given by Bobby).
Of course, this is rather advanced analysis of our soup of data living
in the repository but I think that some of the things that Xun is
planning to do would be perfectly applicable here (his unsupervised
tagging in particular).
Xun, what do you think?
Cheers,
- Philippe
