Tuplespace-based computing for the Semantic Web: a survey of the state-of-the-art

Abstract

Semantic technologies promise to solve many challenging problems of the present Web applications. As they achieve a feasible level of maturity, they become increasingly accepted in various business settings at enterprise level. By contrast, their usability in open environments such as the Webwith respect to issues such as scalability, dynamism and openness-still requires additional investigation. In particular, Semantic Web services have inherited the Web service communication model, which is primarily based on synchronous message exchange technology such as remote procedure call (RPC), thus being incompatible with the REST (REpresentational State Transfer) architectural model of the Web. Recent advances in the field of middleware propose 'semantic tuplespace computing' as an instrument for coping with this situation. Arguing that truly Webcompliant Web service communication should be based, analogously to the conventional Web, on shared access to persistently published data instead of message passing, space-based middleware introduces a coordination infrastructure by means of which services can exchange information in a time-and reference-decoupled manner. In this article, we introduce the most important approaches in this newly emerging field. Our objective is to analyze and compare the solutions proposed so far, thus giving an account of the current state-of-the-art, and identifying new directions of research and development.

Coordination of Knowledge in Pervasive Environments

“…Focusing particularly on the tuple space paradigm, the current research results have been described and compared [5] and ongoing work is being done led by the TripCom project 2 . This small, yet incipient knowledge coordination community draws its experience from both prior tuple space and Semantic Web research, nevertheless it is important to broaden the discussion and gain new insights and perspectives from those outside of these rather narrower groups.…”

Service-Oriented Distributed Applications in the Future Internet: The Case for Interaction Paradigm Interoperability

“…Acknowledging the flexibility of the TS model, a number of system integration efforts have adopted TS as the common interaction facility. Some of these approaches enrich TS with PS semantics, or offer a REST-based API in addition to the TS-based API [19]. Similar efforts introduce extended TS as an alternative solution to the realization of the ESB paradigm [12].…”

Smart Spaces and Smart Objects Interoperability Architecture (S3OiA)

“…S 3 OiA complies with Triple Space (TS) computing that performs a tuplespace based communication using RDF triples, in which the information unit has three dimensions: "subject predicate object", to express this semantic data [17]. Triple Space computing is a coordination paradigm based on tuplespace-based computing, which comes from the parallel computing language Linda [18].…”
