Alejandro -
I think that what you need is HILCC -- Columbia's "Hierarchical Interface to the LC Classification". See https://www1.columbia.edu/sec/cu/libraries/bts/hilcc/ for their information.
At Serials Solutions, we licensed the interface from Columbia a number of years ago, and have been using it (with some modifications) as the basis for our dropdown subject listings.
Cornell University tried applying HILCC to their undergraduate library collection several years ago; see their report at http://www.library.cornell.edu/backstory/v1n1/hilccfeature.htm.
What I've found so interesting in comparing the two approaches is the places where the hierarchical approach doesn't work so well in each system. For example, at Cornell, they found that it was problematic in the literature headings, since such a large number of the volumes in their undergraduate library were literature titles. At Serials Solutions, that's never been an issue, but we have problems with legal headings, especially non-US headings, since so many journals are assigned to general headings like "Law, Politics, & Government --> Law - U.S." It's also not specialized enough for medical librarians, law librarians -- heck, anyone who feels that what they do is a specialty!
Of course, what it does do is assign a hierarchical subject heading to an LC class number, and it does that well. Whenever we make a new journal or resource record in our internal database, our system takes the class number from the MARC record and it automatically assigns a hierarchical subject heading to the journal. Headings can also be assigned by hand, but this is done on the fly as we create new journal records.

Subject: [NGC4LIB] LCC to Conspectus service / webservice?
I need something that will map an LC class number into one of many
"subject groups" exactly like or similar to the OCLC Conspectus.
Hopefully, I could do this on the fly, programatically, with a web
service of some sort.
Is this something that Is In Breach of some legal agreement or licensing
regarding the OCLC Conspectus? If I look at conspectus reports from a
library, look at LC Class ranges in ClassWeb, and build something that
maps one to the other, is this ?
I just want to do what the OCLC Collection Analysis service does, but
one item at a time, to then let users navigate an OPAC by that
dimension. (Hopefully, we'd then have a hierarchical way to navigate
thru items catalogued with LCCs).
