The TNTBase System and Validation of XML Documents

TNTBASE is an open-source versioned XML database obtained by integrating Berkeley DB XML into the Subversion Server. The system is intended as a basis for collaborative editing and sharing XML-based documents. It integrates versioning and fragment access needed for finegranular document content management. Nowadays well-formedness of electronic documents plays a giant role in the contemporary document workflows and applications have to provide domain-specific validation mechanisms for documents they work with. On another hand, XML is coming of age as a basis for document formats, and even though there are a lot of schema-based validation formats and software available for XML, domain-specific directions still remain unfilled. In this paper we present the TNTBASE system in general and its validation support for XML documents.
