Active XML (AXML) research: Survey on the representation, system architecture, data exchange mechanism and query evaluation

Active XML (AXML) is an extension of XML to exploit the powerful computation ability of peer-to-peer network and Web services technologies. AXML is considered a distributed XML DBMS which extends the capability of XML by embedding intensional XML data inside XML documents. The management of intensional XML and XML data together in XML documents raises issues such as representation for intensional XML data, AXML–XML data exchange and AXML data query processing. This paper will study these issues, comparing as well as discussing the current solutions to AXML systems.
