Subject [greenstone-users] Can Greenstone index several levels down?
Thanks!!! This is exactly what I was looking for; and also thanks for the example. I take it that there is no limit to how far down these
subject-browsing levels can go [i.e.: recurse [If that's a word?]

I take it then that there would also be no limit on the number of browsing levels down that I could go for, say, a country button??? eg.:

Country of Far Away

County of the Stuffy Count

Town of Whatever-Its-Name-Is

Village of Hamlin

Hamlet of Tinyplace

No.1 Allen's Alley

[etc. until I run out of disk space???]

The folks we're working with on the grant will want to enable browsing levels down to extremely fine granularities of subject and
geographical location buttons. [I'm not just being silly and/or theoretical. I'd ask Ian when he comes up to New York next month, but the
grant application is due very soon.]

Hi David

Are you talking about browsing classifiers? Eg a subjects button on the
navigation bar, which gives you a top level of basic subjects, which can
be further exanded to more specific subjects?

You can do this in greenstone, see e.g.
http://www.nzdl.org/cgi-bin/library?a=d&cl=CL1&c=hdl <http://www.nzdl.org/cgi-bin/library?a=d&cl=CL1&c=hdl>
The subjects classifier for the humanity development library.

This can be achieved by using the Hierarchy classifier with either
hierarchical metadata (e.g. Trucks|Trucks military|Trucks military -
or using a supplementary file containing the hierarchy. (see section 2.2
of developers guide)
