Design and Implementation of a Document Database Extension
Integration of text and documents into database management systems has been the subject of much research. However, most of the approaches are limited to data retrieval. Collaborative text editing, i.e. the ability for multiple users to work on a document instance simultaneously, is rarely supported. Also, documents mostly consist of plain text only, and support very limited meta data storage or search. The authors address the problem by proposing an extended definition of document data type which comprises not only the text itself but also structural information such as layout, template and semantics, as well as document creation meta data.
