Abstract: | This paper provides an overview of the Active XML project developed at INRIA over the past five years. Active XML (AXML, for
short), is a declarative framework that harnesses Web services for distributed data management, and is put to work in a peer-to-peer
architecture. The model is based on AXML documents, which are XML documents that may contain embedded calls to Web services, and on AXML services, which are Web services capable of exchanging AXML documents. An AXML peer is a repository of AXML documents that acts both as a client by invoking the embedded service calls, and as a server by providing
AXML services, which are generally defined as queries or updates over the persistent AXML documents. The approach gracefully
combines stored information with data defined in an intensional manner as well as dynamic information. This simple, rather
classical idea leads to a number of technically challenging problems, both theoretical and practical. In this paper, we describe
and motivate the AXML model and language, overview the research results obtained in the course of the project, and show how
all the pieces come together in our implementation.
