摘 要: 隨著材料科學(xué)的迅猛發(fā)展， 材料信息量以空前的速度增長(zhǎng)。 Internet的普及使材料信息的獲取更加快捷、 方便， 現(xiàn)在Internet上已有許多免費(fèi)的材料信息數(shù)據(jù)庫(kù)。 但由于這些材料數(shù)據(jù)庫(kù)分布在各個(gè)不同的服務(wù)器上， 操作系統(tǒng)、 存儲(chǔ)方式都各不相同， 這給材料信息的查詢、 分析帶來(lái)很大的困難。 Web Services是一種面向服務(wù)的體系結(jié)構(gòu)， 其優(yōu)點(diǎn)是實(shí)現(xiàn)了真正意義上的平臺(tái)獨(dú)立性和語(yǔ)言獨(dú)立性。 將基于FIPA和元數(shù)據(jù)的Agent技術(shù)與Web service技術(shù)應(yīng)用到材料信息的集成系統(tǒng)的建設(shè)， 分析了分布式材料信息中Agent的分類與結(jié)構(gòu)， 利用JADE（Java Agent Development Environment）設(shè)計(jì)了一個(gè)面向分布式材料信息的多Agent原型系統(tǒng)Material-Agents， 并開(kāi)發(fā)了一種腳本語(yǔ)言Material-script。

Abstract:With the fast development of material science and technology, the information of material increases rapidly. Internet makes the acquirement of material information more easily and quickly. The material databases are heterogenous and distributed. This makes the query and analysis of material information very difficult. Web service is a service oriented architecture . It is platform independent and language independent. The agent technology based on FIPA and metadata and web service technology were applied into constructing integrated framework of material information system. Firstly, the classification and structure of agent in distributed material information were analyzed. Then the proto system material-agents for the distributed material information multi-agent system was designed using JADE（java agent development environment）； a script language material-script was also developed.
Key words: agent; distributed material information; material-agents; material-metadata; FIPA; JADE
