读取OSLC响应时出错&；使用jena执行sparql

我使用oslcv2.0从clearquest（作为RDF）获取数据，将其保存为“.RDF”文件，并使用apachejena对该文件执行sparql查询

来自OSLC响应的数据：

<?xml version="1.0" encoding="UTF-8"?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
    xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#" xmlns:oslc="http://open-services.net/ns/core#"

    </oslc:ResponseInfo>
    <rdf:Description rdf:about=".....">

         .......
            <cq:vehicle>

            </cq:vehicle>
            <cq:vehicle>
                <cq:type>car</cq:type>
            </cq:vehicle>
            <cq:vehicle>
               <cq:type>bike</cq:type>
               <cq:type>car</cq:type>
            </cq:vehicle>
          .......
        </cq:user>
        .......
         other user records
        .......
    </rdf:Description>
</rdf:RDF>

当我试图在这个数据上执行SPARQL时，我得到了以下错误

根据，如果使用Accept标头或rcm.contentType未请求任何内容类型，则返回RDF/XML

以下其中一项出现问题
1.来自Clearquest的RDF/XML响应
2.将其保存为“.rdf”文本
3.使用ApacheJena读取数据

---

找不到问题所在。。请帮忙。。提前感谢：）

如异常所述，RDF数据无效。您可以看到存在问题的行和列。错误出现在自行车车的这一部分，其中两种类型的车和自行车位于同一车辆标签下。。但这是Clearquest的输出。。。
