Question

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SPARQL源代码根据http://spinrdf.org/sp.html中http://spinrdf.org/sp指定的模式在RDF结构中进行标记/编码。正是这种结构实际上被RDF4J解释为运行SPIN规则。

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。

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。

另请注意，我知道存储原始SPARQL查询文本的选项。但是，我的经验是，没有正确解释这一点，而令牌化/结构化的RDF被正确解释。因此，我必须使用结构化的RDF。

我希望已经编写了许多用于编码的Java代码，可能是Apache Jena的一部分。我只需要一个指向哪里看的指针。

谢谢！

PS：这是由TBC FE编码的示例SPIN构造函数的开始。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。

正如@AKSW指出的那样，与Jena库结合的SPIN API可以实现我所追求的目标。 TopBraid的SPINParsingExample.java非常接近我想做的事情。

我确实需要在我的Eclipse项目和Build Path中添加一个SPIN库和几个Jena库文件（// Assign the location of the persons ics files to a variable to use later, then scan through all the files // and place them in an array. $personCalendars = '../folder01/calendars/person'; $personFiles = scandir($personCalendars); // Find the ID of the person hat is logged in by looking through the session information. $personID = $_SESSION['person_ID']; // Get the url of the page that we are on and check the server name. function url(){ return sprintf('%s//%s%s', isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off' ? 'https:' : 'http:', $_SERVER['SERVER_NAME'], $_SERVER['REQUEST_URI'] ); } // Find the ID of the person in the file array $getURL = preg_grep('/'.$personID.'/',$personFiles); // Set the pointer of the array to the first part of the url $filename = reset($getURL); // If there is an ics file for the person, grab the URL of the page and add on the filename // eg: portal.company/index.php/calendar?99203.ics // If no file is found, say so. if ($filename){ $fullURL = url() . '?' . $filename; echo $fullURL; }else{ echo 'File not found\n'; }文件）。我知道有自动方法来处理这些依赖关系，但是现在我手动完成它。对于那些也手动完成的人，这些文件列在下面......

SPIN库：

spin-2.0.0.jar

Apache Jena库（最好按照评论中的建议使用3.0.1）：

如何从Java将SPARQL / SPIN查询/规则转换为RDF结构？
