Hierarchical taxonomy

[Stefan Wild]

A client of mine has requested a full-fledged taxonomy (as opposed to
the existing category tree that basically displays keywords
hierarchically). I know this has been thought about a few times and
there were actual plans to realize it. However, nothing ever surfaced.
Who knows more? And are there existing concepts on how to go about
this?

Regards,
Stefan

Picking up an old thread here. 
I'm setting up RS to manage images of marine species.  At the moment I'm using a dynamic keyword list, pre-loaded with a list of the more common species.  This makes it relatively easy for data entry but has some drawbacks - I can't prevent a user adding mis-spelt new species and it won't be possible to search at a higher taxonomic level than the one entered.  Linking common names to scientific names is also difficult. I could set up a category tree but this would soon grow very large and it would be difficult for users to find their way through - they may be confident of the species name but not know how to navigate through the tree to get there. Something that is part dynamic keyword and part category tree might work - start typing to provide an ever-narrowing list of species to choose from and then add parent keywords to the field automatically.
There is a definitive taxonomic list available, each taxon has a unique ID, parent, taxonomoc level and other values, such as common names. It would be great to incorporate this with a user-friendly taxonomic field in RS.
I realise this is a niche market and that this would probably require funding.  Is there anyone who could help develop this and what sort of costs are we talking about?  Is there any wider interest in such a facility?

Hi, Peter,

This is a generalized need, and is not specific to scientific
taxonomy. For example, the Getty Vocabularies (frequently used in
library, archival, and museum cataloging) follow a similar
hierarchical structure. (See
http://www.getty.edu/research/tools/vocabularies/ ) Similarly, many
organizations have internally-maintained taxonomies. I agree that the
category tree, as currently implemented, is not really adequate for
this sort of thing.

I have some interest in this idea, both as a user and possibly as a
developer. Please let me know if you'd like to discuss.
