问节点属性上的Neo4j SPARQL插件

我有Neo4j 1.9.7和SPARQL插件一起工作(SPARQL1.0)。

我已经将一个.nt文件导入到数据库中，创建了相应的节点和关系。每个节点都有一个属性值，该属性值是节点的名称。是否可以从找到具有特定“值”的节点的插件执行SPARQL查询？

例如节点(2)-价值:BusinessProcess1 1

我的目标是在SPARQL中执行一个类似于Cypher中的查询：

代码语言：javascript
复制
start n=node(*)
match (n)-[r]-(x)
where n.value="http://neo4j.org#BusinessProcess1"
return n,n.value, x, x.value, type(r)

这个查询为我提供了如下输出：

代码语言：javascript
复制
      n              n.value                      x                   x.value              type(r)
    Node 2  "http://neo4j.org#BusinessProcess1" Node 5  "http://neo4j.org#ApplicationProcess2"  "http://neo4j.org#RUN"
    Node 2  "http://neo4j.org#BusinessProcess1" Node 3  "http://neo4j.org#ApplicationProcess3"  "http://neo4j.org#RUN"
    Node 2  "http://neo4j.org#BusinessProcess1" Node 10 "http://neo4j.org#ApplicationProcess39" "http://neo4j.org#COMPOSED_BY"
    Node 2  "http://neo4j.org#BusinessProcess1" Node 5  "http://neo4j.org#ApplicationProcess2"  "http://neo4j.org#COMPOSED_BY"
    Node 2  "http://neo4j.org#BusinessProcess1" Node 157    "http://neo4j.org#ApplicationProcess12" "http://neo4j.org#COMPOSED_BY"
    Node 2  "http://neo4j.org#BusinessProcess1" Node 192    "http://neo4j.org#ApplicationProcess1"  "http://neo4j.org#COMPOSED_BY"
    Node 2  "http://neo4j.org#BusinessProcess1" Node 45 "http://neo4j.org#ApplicationProcess7"  "http://neo4j.org#COMPOSED_BY"
    Node 2  "http://neo4j.org#BusinessProcess1" Node 80 "http://neo4j.org#ApplicationProcess34" "http://neo4j.org#COMPOSED_BY"

有可能这样做吗？

这是相当愚蠢的，我可以直接使用作为值广告，做这样的查询
