The Resource Description Framework (RDF) is a method to describe and exchange graph data. It was originally designed as a data model for metadata by the World Wide Web Consortium (W3C). It provides a variety of syntax notations and formats, of which the most widely used is Turtle (Terse RDF Triple Language).

A triplestore or RDF store is a purpose-built database for the storage and retrieval of triples [1] through semantic queries. A triple is a data entity composed of subject – predicate – object, like "Bob is 35" (i.e., Bob's age measured in years is 35) or "Bob knows Fred".

We need to be able to persistently store and manipulate (large amounts of) RDF data. One of the alternatives to do that is to use the relational database technology. A major advantage of this approach is that is provides a scalable off-the-shelf solution. Scalability: can …

本文首先介绍W3C的 RDB2RDF工作小组 制定的两个标准，用于将关系型数据库的数据转换为RDF格式的数据。然后介绍如何利用d2rq这个工具把我们Mysql中的数据转为RDF。

The RDF model represents information as triples in the form of subject-predicate-object. Database management systems, which are able to store and process such triples, are called RDF stores or triple stores.

2022年11月4日 · In this tutorial, we’ll introduce the concept of Resource Description Framework (RDF) and its main characteristics, how to use it, and for what. RDF is a model to represent data about physical objects and abstract concepts. It’s a model to express relations between entities using a graph format.

RDF is a standard way to make statements about resources. An RDF statement consists of three components, referred to as a triple: Subject is a resource being described by the triple. Predicate describes the relationship between the subject and the object. Object is a …

结构化数据到RDF由两种主要方式，一个是通过direct mapping，另一个通过R2RML语言这种，基于R2RML语言的方式更为灵活，定制性强。 对于R2RML有一些好用的工具，此处我们使用d2rq工具，它基于R2RML-KIT。

2016年9月29日 · Unlike relational databases which store data in tables, triplestores store data as statements in the Subject-Predicate-Object form, such as “Jessica teaches Computer Science”; each statement is called a triple. This data representation uses the Resource Description Framework (RDF), a standard model for publishing and sharing data on the Web ...
