Xhoo is a collaborative project whose goal is to create Open Source Web Catalog software for various platforms and languages that can selectively import data from the Open Directory Project. This project is currently being supported by Webreference.com. Early releases are currently available for Perl, ASP, and PHP. There are several related articles that appeared at Mother of Perl that you may want to take a look at.

PerlHoo | Download PerlHoo uses comma delimited files and filesystem directories to store the Web catalog. PerlHoo currently is made up of 2 CGI scripts: perlhoo.pl - Perl script to display catalog phadmin.pl - Used to administer the catalog Related Articles: PerlHoo, Part I PerlHoo, Part II PerlHoo, Part III PerlHoo was written by Jonathan Eisenzopf.

Yahasp | Download Yahasp is very similar to PerlHoo. The main difference, of course, is that it was written as an ASP script. Related Articles: Yahasp: A PerlHoo Alternative Yahasp was written by Lawrence Gold.

phpHoo | Download phpHoo uses MySQL to store the catalog instead of filesystem directories and comma delimited files. PerlHoo and Yahasp will probably move to this model in future versions. Related Articles: phpHoo: A strong competitor to PerlHoo phpHoo was written by CDI.
