将带有空白节点的三元组插入 Amazon Neptune 实例时:
INSERT DATA { <http://example.com/s> <http://example.com/p> _:something }
…空白节点的值被替换为b<SOME NUMBER>
. 运行这样的查询:
SELECT ?o WHERE { <http://example.com/s> <http://example.com/p> ?o }
…将返回如下内容:
{
"results": {
"bindings": [
{
"o": {
"type": "bnode",
"value": "b24508943"
}
}
]
}
}
将数据加载到 Neptune 时,有没有办法保留原始的空白节点名称?
