The LaQuAT (Linking and Querying Ancient Texts) project investigated technologies for providing integrated SQL-based views of diverse data resources related to classical archaeology, specifically containing epigraphic and papyrological material. These resources were quite heterogeneous in terms of standards and structure, comprising two relational databases with different schemas, and an XML-based corpus; they are hosted by different institutions in different countries, and are the outputs of divergent research communities. Nevertheless, the datasets overlapped geographically, chronologically and prosopographically. Such issues are typical of archaeological databases; to address them the project explored the applicability of 'grid computing', and in particular the OGSA-DAI software, for providing integrated views of such diversity.
