Hello, I've just commited a new feature, called "catalogue browsing". A new script in misc/cronjobs/build_browser_and_cloud.pl will fill 2 new tables. - One for "tag cloud" searching : the tags are not filled by the users themselves, but from the catalogue. I plan to add later a feature to have a user-level tag system + a p2p system to share tags. for instance the "tag cloud" table will be filled from the catalogue only. - One for "Catalogue browsing" : depending on the parameters you give to build_browser_and_cloud.pl script, you'll fill the browser table, that let the user browse the catalogue. If you have dewey classification in your catalogue, you'll be able to dig the dewey hierarchy (3 => 31 => 311 => 311.2 ...), and define description for the 3, 31, 311... french dewey has been commited & you can see the result at : http://o17.bureau.paulpoulain.com/cgi-bin/koha/opac-browser.pl It should be easy to add english dewey, Loc classification or any other hierarchic classification. TO DO : - improve the build_... script, to have an option to update only last-week bilbio modifications. This can be made easily, but at the price of imprecision in the counters, which is cheap imho. The "complete" calculus can be run once a month anyway. But note that, on my computer, it calculates 50 biblios/seconds - add a screen, in admin section, to let the library define their descriptions for the browser. -- Paul POULAIN et Henri Damien LAURENT Consultants indépendants en logiciels libres et bibliothéconomie (http://www.koha-fr.org) Tel : 04 91 31 45 19
