Embodiment Construction

[0022] In the following, exemplary embodiments of the XML database system and method of the present invention are described. It will be appreciated that the functionality described below can be implemented in many alternative ways, eg on a single database server, on a distributed arrangement of multiple database servers, with integrated memory or external memory, etc. These implementation details are not essential to the invention.

[0023] figure 1 An overview of an exemplary XML database system 1 is given. System 1 is typically used to store and retrieve XML documents ( figure 1 not shown). However, figure 1 XML database systems are also capable of handling non-XML documents, e.g. figure 1 Exemplary media files shown in 10. The media file 10 may be any type of non-XML document, such as video files, audio files, a combination of video and audio files, images, MS Office documents, any collection of binary data such as measurement results, and the like.

Abstract

The invention discloses a method for processing a non-XML document (10) stored in an XML database. The method comprises the following steps: generating a shadow XML document (20) for the non-XML document (10) in accordance with a predetermined XML schema (50), wherein the shadow XML document(20) comprises metadata extracted from the non-XML document(10); storing the shadow XML document(20) and the non-XML document (10) in the XML database; wherein the XML schema (50) comprises a wrapping element (51) adapted to wrap XML content of an at least partly undefined XML structure.

Description

technical field [0001] The invention relates to a method and database system for processing non-XML documents for storage in an XML database. Background technique [0002] XML database is one of the most important technical tools in modern information society. The high flexibility of such databases allows data to be stored and retrieved in a very efficient manner. Generally, XML databases are designed for XML documents. However, it is also known in the prior art to extend an XML database so that it can store other types of documents. For example, Applicant's XML database Tamino is suitable for storing non-XML documents such as text files, MS Office files, PDF files, image and audio files, and the like. In order to enable retrieval of such non-XML documents from a database, it is known to analyze the non-XML document to be stored and extract some metadata for generating a so-called XML shadow document corresponding to the non-XML document. Using XQuery, the shadow XML doc...
