ElasticSearch连接器-属性链中的反向IRIs

Question

我在9.7发布说明中看到:

GDB-5477在连接器属性链中增加对反向IRIs的支持

这个功能可用吗?我在ES Connectors页面中找不到文档。

Answer 1

如果您想要过滤掉特定的属性链，该功能非常有用。为例:

{
"fieldName":"operatesEquipment_variantOfFamily_label",
"propertyChain":[
"^http://example.com/nested/other/operatedBy",
"^http://example.com/nested/other/owns",
"http://example.com/nested/core/label"
],
"indexed":true,
"stored":true,
"analyzed":true,
"multivalued":true,
"fielddata":false
}

如果你像这样插入数据:

@prefix : <http://example.com/> .
:family2 <http://example.com/nested/core/label> "test" ;
<http://example.com/nested/other/owns> :equipement1 .

预期结果不会有任何与operatedBy或owned相关的内容:

{
"properties": {
"label": {
"store": true,
"type": "text"
},
"operatesEquipment_variantOfFamily_label": {
"store": true,
"type": "text"
}
}
}
