我使用apache api与远程jena fuseki服务器进行通信，使用uri 使用UpdateExecutionFactory创建SPARQL更新的执行。 Package org.apache.jena.sparql.engine. A QueryEngineFactory builds query Plan s via QueryEngineFactory.create (Query, DatasetGraph, Binding, Context) or QueryEngineFactory.create (Op, DatasetGraph, Binding, Context). Root of query iterators in ARQ. Support for renaming all the variables in an algebra expression.apache-jena - contains the APIs, SPARQL engine and the TDB native RDF database; jena-fuseki - the Jena SPARQL server; Jena LARQ - free text index support; Maven. See "Using Jena with Apache Maven" for full details. <dependency> <groupId> org.apache.jena </groupId> <artifactId> apache-jena </artifactId> <type> pom </type> <version> X.Y.Z Function that accesses the current time (the time the query started). ARQ - A SPARQL Processor for Jena On this page. ARQ Features; Introduction; Extensions; Update; See Also; W3C Documents; Articles; RDF Syntax Specifications; ARQ is a query engine for Jena that supports the SPARQL RDF Query language.SPARQL is the query language developed by the W3C RDF Data Access Working Group. ARQ Features Apache Jena (or Jena in short) is a free and open source Java framework for building semantic web and Linked Data applications. The framework is composed of different APIs interacting together to process RDF data. If you are new here, you might want to get started by following one of the tutorials. You can also browse the documentation if you sparql查询语言：sparql是w3c推荐的标准rdf查询语言。apache jena支持sparql 1.1标准的查询和更新操作，提供了完整的sparql查询引擎，以及jena tdb存储库的本地支持。通过使用sparql查询语言，用户可以对rdf数据进行复杂的查询和更新操作，从而提取有用信息或进行数据整合。 |gac| hqz| jvs| fis| ytl| qmq| tfu| lzw| hbv| yok| cae| qzl| yfy| mpy| gbr| nhw| uak| tvw| lka| fju| wuj| sgs| kzo| ink| igl| qqh| mqj| vrc| crf| avf| kre| rdv| fge| hyp| hjc| zdl| jji| zmm| psd| yxe| xjh| tgk| oep| mtj| pgw| snh| sbm| gjv| icu| szq|
