gstore-sparql-query's Introduction

gStore SPARQL Query

设计简述

gStore 是一个基于图的 RDF 数据管理系统(也称为“三元组存储”),维持了原始 RDF 数据的图结构。它的数据模型是有标签的有向多边图,每个顶点对应一个主体或客体。

本系统使用 DBpedia 中的 music 数据集,基于 Spring Boot 框架构建后端逻辑,利用图数据库 gStore 实现数据库存储和查询,以此构建面向 DBpedia RDF 知识库的音乐领域的数据的 Web 查询系统,本系统目前支持 HTML 格式数据的表格展示,以及 HTML/JSON/CSV/TXT 等格式的查询结果的文件下载功能。

本项目可在操作系统 Ubuntu 16.04 下进行运行测试。
