问题描述
我正在尝试学习在Fuseki中更新数据，但是当我尝试时出现404错误.我显然做错了什么.也许这是我的INSERT命令?我尝试了很多.
I'm trying to learn to update data in Fuseki, but when I try I get a 404 error. I am clearly not doing something right. Perhaps it is my INSERT command? I've tried a ton of them though.
我正在/sparql.tpl使用基于Web的SPARQL界面.
I am using the web based SPARQL interface at /sparql.tpl.
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 Updates)是我用于更新的形式，这给了我错误:
I can get SPARQL Queries to work on that same page just fine. But the second form, labeled SPARQL Updates is what I'm using for my update, and that gives me errors:
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
}
这是当表单发布到url localhost:3030/bookfinder/update时出现的错误:
This is the error I get when the form posts to the url localhost:3030/bookfinder/update:
Error 404: Not Found
Fuseki - version 1.0.1 (Build date: 2014-01-18T19:01:20+0000)
这是我的TTL文件.
This is my TTL file.

有什么猜想吗?
推荐答案
正如我对问题的评论中所述，问题是在启动时需要添加"--update"标志.参见 http://jena.apache.org/documentation/serving_data/
As explained in the comments on my question, the problem was the "--update" flag needed to be added at startup. See http://jena.apache.org/documentation/serving_data/
