SPARQL 查询的问题
我的以下查询不起作用：
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema%23>
PREFIX i: <http://evolizer.org/ontologies/seon/2010/09/softwaremetrics.owl%23>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns%23>
SELECT ?metric ?value
WHERE {
?metric rdf:type i:SoftwareDesignMetric .
?metric i:hasName "NOM" .
?metric i:hasValue ?value
?metric i:isMetricOf "http://130.60.156.155:8080/famixParser/projects/argouml/org.argouml.pattern.cognitive" .}
我使用 查询验证器 抛出以下异常：
Encountered " "?metric "" at line 9, column 1.
Was expecting one of:
"graph" ...
"optional" ...
"service" ...
"minus" ...
"filter" ...
"{" ...
"}" ...
";" ...
"," ...
"." ...
但我不知道这意味着什么
I have the following query that is not working:
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema%23>
PREFIX i: <http://evolizer.org/ontologies/seon/2010/09/softwaremetrics.owl%23>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns%23>
SELECT ?metric ?value
WHERE {
?metric rdf:type i:SoftwareDesignMetric .
?metric i:hasName "NOM" .
?metric i:hasValue ?value
?metric i:isMetricOf "http://130.60.156.155:8080/famixParser/projects/argouml/org.argouml.pattern.cognitive" .}
I used a query validator that throws the following exception:
Encountered " "?metric "" at line 9, column 1.
Was expecting one of:
"graph" ...
"optional" ...
"service" ...
"minus" ...
"filter" ...
"{" ...
"}" ...
";" ...
"," ...
"." ...
But i don't know what that means

您可能想在图形模式
?metric i:hasValue ?value之后添加句点.。You probably want to add a period
.after the graph pattern?metric i:hasValue ?value.
