好吧，我检查了字符串模式，[ABC]表示字母A或B或C。但是NamedIndividual PatternA有字符串zzzzz，它不符合[ABC]。

看起来HermiT不支持推理整数：

org.semanticweb.HermiT.datatypes.UnsupportedFacetException: The datatype rdf:PlainLiteral accepts only integers as facet values for the facet with URI 'http://www.w3.org/2001/XMLSchema#length', but in the ontology we have a datatype restriction org.semanticweb.HermiT.datatypes.rdfplainliteral.RDFPlainLiteralDatatypeHandler@685f8461. The value '"8"^^xsd:string' does not seem to be an integer.

问题已更新：推理已更改。并添加了新属性

现在我收到了错误：

Answer 1

FaCT ++的例外说不支持你正在使用的方面 - 这是FaCT ++实现的限制。

关于HermiT，你得到的错误是由于：

<xsd:length rdf:datatype="&xsd;string">8</xsd:length>

数据类型需要是int（或整数），而不是字符串。

保护：FaCT ++为什么不报告不一致？
