问题描述

我一直在使用TopQuadrant Composer免费版（TBC FE）在存储为RDF的OWL本体中嵌入SPARQL / SPIN规则（主要是SPIN构造函数）。此过程的一部分是根据，该模式在中指定。正是这种结构实际上被RDF4J解释为运行SPIN规则。

I have been using TopQuadrant Composer Free Edition (TBC FE) to embed SPARQL/SPIN rules (primarily SPIN constructors) in my OWL ontologies stored as RDF. Part of this process is that the SPARQL source code is tokenized/encoded in an RDF structure according to http://spinrdf.org/sp.html which the schema specified in http://spinrdf.org/sp. It is this structure that actually gets interpreted by RDF4J to run the SPIN rules.

我也使用RDF4J作为我的三重存储，推理器，SPARQL端点和SPIN规则引擎。另外，我正在生成自定义Java代码和GUI来操纵我的数据和规则。

I'm also using RDF4J as my triple store, reasoner, SPARQL endpoint, and SPIN rule engine. In addition, I'm generating custom Java code and GUIs to manipulate my data and rules.

我的问题是我可以在Java中使用什么来将SPARQL / SPIN源代码编码为RDF ？请注意，我不询问如何编码查询结果（在另一个stackoverflow问题/响应中回答），而是如何编码查询本身。原因是我想从我自己的Java代码中启用SPIN规则的编辑，而不是完全依赖于TBC FE。

My question is what can I use in Java to encode SPARQL/SPIN source code as RDF? Note that I'm not asking how to encode query results (which was answered in another stackoverflow question/response) but rather how to encode the query itself. The reason is that I would like to enable editing of SPIN rules from my own Java code rather than being solely reliant on TBC FE.

另请注意我知道的存储原始SPARQL查询文本的选项。但是，我的经验是，未正确解释这一点，而正确解释了标记化/结构化的RDF。因此，我必须使用结构化的RDF。

Also note that I'm aware of the option to store the original SPARQL query text. However, my experience has been that this is not correctly interpreted whereas the tokenized/structured RDF is correctly interpreted. Therefore, I must use the structured RDF.

我希望已经编写了许多用于执行此编码的Java代码，可能是Apache Jena的一部分。我只需要一个指针来查看。

I'm hoping that much of the Java code to do this encoding is already written, perhaps as part of Apache Jena. I just need a pointer as to where to look.

谢谢！

PS：这是示例的开头由TBC FE编码的SPIN构造函数。它包括SPARQL / SPIN源代码的原始sp：文本和结构化RDF的开头（在sp：text块之后）。这是我需要能够使用Java从SPARQL源代码生成的结构化RDF。

PS: Here's the start of example SPIN constructor encoded by TBC FE. It includes both the original sp:text of the SPARQL/SPIN source code and the start of the structured RDF (after the sp:text block). It's the structured RDF that I need to be able to generate using Java from the SPARQL source code.
