输出格式在耶拿Fuseki服务器 [英] output format in Jena Fuseki server
问题描述
前缀dm:< http://one.example/>
SELECT?pID
WHERE
{
?pID dm:hasDNamexxxvvvII。
arq引擎输出以下内容:
-------------------
| pID |
===================
| dm:C002172 |
-------------------
<
$ b
{
head:{
vars :[pID]
},
results:{
bindings:[
{
pID:{type:uri ,value:http://one.example/C002172}
}
]
}
}
第一个问题:如何使Fuseki服务器输出的结果更具可读性,无需使用所有大括号和其他标记?
$ b
第二个问题:
如何从Fuseki服务器删除数据集,控制面板中没有这个选项,我在网上搜索。但我能找到的是这样的:
http://jena.apache.org /documentation/serving_data/soh.html
我在终端上试过这些命令,但实际上并没有工作吗?
感谢您的帮助和快速响应!
解决方案
-
要求格式文本/纯文本输出=文本)。此外,CSV或TSV格式可能对您有用。
Re:删除数据集。不在当前版本中。你可以清空它们,或者是SOH DELETE或PUT中的空内容,或者是PUT空的内容(例如N-Quads)到 http:// localhost:3030 / dataset / 使用curl,wget。
given this command:
prefix dm: <http://one.example/>
SELECT ?pID
WHERE
{
?pID dm:hasDName "xxxvvvII" .
}
The arq engine outputs the following:
-------------------
| pID |
===================
| dm:C002172 |
-------------------
The fuseki server outputs the following:
{
"head": {
"vars": [ "pID" ]
} ,
"results": {
"bindings": [
{
"pID": { "type": "uri" , "value": "http://one.example/C002172" }
}
]
}
}
first question: how can I make the Fuseki server output the result in a more readable way with out the all braces and other token?
second question:
How can I delete datasets from Fuseki server, There is no such option in the control panel and I searched online. But all I can find is this:
http://jena.apache.org/documentation/serving_data/soh.html
I tried these command in the terminal but they didn't actually work?
I appreciate your help and quick response!
解决方案
Ask for format text/plain (content negotiation or ?output=text). Also CSV or TSV formats may be useful to you.
Re: deleting datasets. Not in the current release. You can empty them though, either each graph as in SOH DELETE or PUT of empty content, or PUT empty content (e.g. N-Quads) to http://localhost:3030/dataset/ using curl, wget.
