At http://mediterraneanceramics.org/typology, you'll see a *highly* experimental beginning of what will become a broad ceramic typology for the Mediterranean. That page links to individual pages for major categories with well known typologies. There is also a sylk-formatted spreadsheet of the whole typology available for download.
Think of this as a .01 release. If you look at the xhtml you'll see the beginnings of a bibliographic infrastructure that will be exposed soon. In general, the xhtml file will try to capture the inevitable and necessary complexity of current ceramic scholarship, while the spreadsheet will reduce this to a column-oriented format that is usable in existing database management systems.
