GraphDB 拒绝 OGC GeoSparql SHACL

问题描述 投票：0回答：1

问题：为什么 GraphDB 拒绝 OGC GeoSparql SHACL 约束？

背景

GraphDB 支持 针对传入和现有数据进行 SHACL 验证。 OGC 为 GeoSparql 标准提供了shapes，并在形状文件中包含了传递和非传递数据。

我的存储库设置为启用 SHACL，启用 GeoSparql 插件，并且默认命名图形用于形状。

将形状插入到形状的默认命名图形中时，

http://rdf4j.org/schema/rdf4j#SHACLShapeGraph
，我遇到以下异常和堆栈跟踪

org.eclipse.rdf4j.repository.RepositoryException: org.eclipse.rdf4j.sail.SailException: Invalid shacl constraint pattern: "^\s*$|^\s*({)(.*)(})\s*$"^^<http://www.w3.org/2001/XMLSchema#string>

我实际上并没有在形状中看到这种模式，这就是我的困惑开始的地方。我还能够使用 pyshacl 毫无问题地处理形状，所以我很好奇这是否可能是 GraphDB 中的某个错误。

正如 UninformedUser 提到的，OGC 提供的正则表达式与 Java 的正则表达式解析器不兼容。此外，GraphDB 目前不支持 OGC GeoSPARQL 1.1 SHACL 语法。
