XMLBase researched analysis, design and implementation methods for systems for management of semi-structured data distributed over the Internet.
XMLBase is a component-based framework for indexing and searching collections of XML (and HTML) documents. The framework is used to conduct multiple performance analysis measurements that have been used do compare strategies for storing, versioning, indexing and querying XML data collections.
This provided a validation environment, upon which we built a prototype Web application (the Tumba! search engine) that we used as a benchmark for comparing various alternative strategies for collecting, storing, indexing and querying Web data.
