开源的 D2RQ 接口让您可以将关系数据当作一个三元组集合对待，因而该数据可以合并到这样的应用程序中。
The open source D2RQ interface lets you treat relational data as a collection of triples so that this data can be incorporated into such an application.
为了便于以后提供这种功能，将EIDB中的共同提及数据转换为一个面向三元组的模式，实现的方法是在数据库上定义一个具有这种结构的视图。
To accommodate this future possibility, the co-mention data in the EIDB is cast into a triples-oriented schema by defining a view on the database that has this structure.
在这个示例中，where子句的图形模式中的第一个三元组与foaf： name属性为“Jon Foobar”的节点匹配，并把它绑定到名为contributor的变量。
In this example, the first triple in the WHERE clause's graph pattern matches a node with a foaf: name property of "Jon Foobar," and binds it to the variable named contributor.
