| 中文简介: |
我们提出了一个本体，用于表示具有读写链接数据接口的组件上的工作流，并通过规则语言为本体提供了操作语义。工作流语言已成功地应用于企业信息系统中的行为建模，其中数据通常在关系数据库中进行管理。链接数据接口已广泛部署在网络上，以支持非常多样化领域的数据集成，越来越多地也应用于涉及物联网的场景，其中应用程序行为通常使用命令式编程语言来指定。在我们的工作中，我们的目标是将允许非专家用户对应用程序行为进行高级规范的工作流语言与允许分散数据发布和集成数据访问的链接数据相结合。我们证明了我们的本体论具有足够的表达力，足以涵盖基本的工作流模式，并通过原型系统演示了我们方法的适用性，该原型系统观察飞行员在混合现实飞机驾驶舱中执行任务。在建筑自动化领域的综合基准上，运行时与物联网设备数量的大小成线性关系。

| 课程简介: |
We present an ontology for representing workflows over components with Read-Write Linked Data interfaces and give an operational semantics to the ontology via a rule language. Workflow languages have been successfully applied for modelling behaviour in enterprise information systems, in which the data is often managed in a relational database. Linked Data interfaces have been widely deployed on the web to support data integration in very diverse domains, increasingly also in scenarios involving the Internet of Things, in which application behaviour is often specified using imperative programming languages. With our work we aim to combine workflow languages, which allow for the high-level specification of application behaviour by non-expert users, with Linked Data, which allows for decentralised data publication and integrated data access. We show that our ontology is expressive enough to cover the basic workflow patterns and demonstrate the applicability of our approach with a prototype system that observes pilots carrying out tasks in a mixed-reality aircraft cockpit. On a synthetic benchmark from the building automation domain, the runtime scales linearly with the size of the number of Internet of Things devices.
