我正在尝试学习更新 Fuseki 中的数据，但是当我尝试时出现 404 错误。我显然没有做正确的事情。也许这是我的 INSERT 命令？不过，我已经尝试了很多。

我在 /sparql.tpl 使用基于 Web 的 SPARQL 界面。

我可以让 SPARQL 查询在同一页面上正常工作。但是第二种形式，标记为 SPARQL 更新是我用于更新的，这给了我错误：

PREFIX dbpedia-owl: <http://dbpedia.org/ontology/>
PREFIX booklet:  <http://www.semanticweb.org/cstepnitz/ontologies/booklet>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX ontology: <http://dbpedia.org/ontology/>

INSERT DATA
{ <http://dbpedia.org/resource/Johnny_Got_His_Gun> 
        rdf:type ontology:Book

}

这是我在表单发布到 url localhost:3030/bookfinder/update 时遇到的错误：

Error 404: Not Found
Fuseki - version 1.0.1 (Build date: 2014-01-18T19:01:20+0000)

这是我的 TTL 文件。

正如对我的问题的评论中所解释的，问题是需要在启动时添加“--update”标志。见http://jena.apache.org/documentation/serving_data/
