Abstract
A new technology for service description and composition in open and distributed environment is proposed. The technology consists of description language (called Entish) and composition protocol called entish 1.0. They are based on software agent paradigm. The description language is the contents language of the messages that are exchanged (between agents and services) according to the composition protocol. The syntax of the language as well as the message format are expressed in XML. The language and the protocol are merely specifications. To prove that the technology does work, the prototype was implemented. A demo of the prototype is available for use and evaluation via web interfaces starting with www.ipipan.waw.pl/mas/ . Related work was done by WSDL + BPEL4WS + (WS-Coordination) + (WS-Transactions), WSCI, BPML, DAML-S, SWORD, XSRL, and SELF-SERV. Our technology is based on similar principles as XSRL, however the proposed solution is different. The language Entish is fully declarative contrary to BPEL4WS and DAML-S. A request (expressed in Entish) describes the desired static situation to be realized by the composition protocol.
The work was supported partially by KBN project No. 7 T11C 040 20
