在Web环境下，一个关键的挑战是如何在全球范围内发布、无缝集成和透明定位地理上分布的信息资源，如数据库、程序、进程等。DartGrid是一个已实现的原型系统，其目标是提供一个能够在网格环境下部署的语义解决方案。DartGrid目前的实现，两个基本的资源，数据和过程，被认为是和集成在一起，提供语义级的服务。我们的方法主要包含以下概念：a）资源提供者被组织成一个基于本体的虚拟组织;通过统一定义的域语义，数据和过程资源可以语义地注册到基于本体的索引并且无缝地集成在一起以提供高级服务，并且，B）我们将与系统的交互级别提高到域认知模型，其中数据查询请求和过程执行命令在域的术语和知识中指定，其使得用户能够查询数据库并在语义或知识级执行处理。我们探讨了语义所扮演的重要和基本的角色，并开发了一个语义浏览器与一些创新的语义功能，如图形浏览RDF/OWL本体，可视化构建语义查询和语义注册的数据和过程资源。
In presence of web, one critical challenge is how to globally publish, seamlessly integrate and transparently locate geographically distributed information resources such as databases, programs, process, etc.DartGridis an implemented prototype system whose goal is to provide a semantic solution capable of deployment in grid settings. With current implementation of DartGrid, two fundamental resources , data and process, are considered and integrated together to provider semantic-level services. Our approach mainly involve the following notions: a) resource providers are organized as an ontology-based virtual organization; by uniformly defined domain semantics, data and process resources can be both semantically registered to an ontology-based index and seamlessly integrated together to provide high-level service, and, b)we raise the level of interaction with the system to a domain-cognizant model in which data query request and process execution command are specified in the terminology and knowledge of the domain(s), which enable the users to query databases and execute processes at a semantic or knowledge level. We explore the essential and fundamental roles played by semantics, and develop a Semantic Browser with some innovative semantic functionalities such as graphically browsing RDF/OWL ontologies, visually constructing semantic queries and semantically registering the data and process resources.
