TDB Assembler Assemblers (装配器) 是Jena中用于描述将要构建的对象(通常是模型和数据集 models & datasets)的一种通用机制.例如, Fuseki 严重依赖使用 Assemblers 来描述模型和数据集. SPARQL 查询是在RDF数据集上操作的.RDF 数据集由一个未命名的默认图( a unnamed, default graph) 和 0个或多个命名图(named graphs)构成. 将数据描述存储在一个文件中,意味着应用程序工作时依赖的数据可…

本体的存储方法或称本体持久化,大致分为基于内存的方式.基于文件的方式.基于数据库的方式和专门的管理工具方式4种(傅柱等, 2013).其中,基于数据库的方式又有基于关系数据库.基于面向对象数据库.基于Native XML数据库和基于NoSQL的三元组数据库(Triple Store)4种主要方式.基于数据库的本体持久化方式充分利用了数据库的安全可靠(数据保密.数据完整性.并发控制.故障恢复等).高效.易于管理并易于与应用系统集成等优点,是主要的本体持久化方式. 在本体中,数据被表示为一系列由主语…
