zOpen Directory lets a Web site developer integrate all of the content of the Open Directory Project (ODP, Dmoz.org) into a Zope website. Since zOpen Directory works by downloading and parsing data from Dmoz.org only when such data is needed, there is no need to download the entire database. The tool is conveniently internationalized, and it features automatic language detection and the ability to run different versions in bilingual or multilingual Web sites. Currently supported languages include English, Basque, Spanish, French, Dutch, Catalan, German, and Italian.
