To query by value in SPARQL, you can use the FILTER clause along with the appropriate comparison operator. Here is an example of how to query for a specific value in a triple pattern:


For example, to query for all resources where the value of a specific property is "example":

1
2
3
4
SELECT ?subject
WHERE {
  ?subject <http://example.org/property> "example" .
}


You can also use other comparison operators such as "=", "<", ">", "<=", ">=" to query for specific values or ranges of values.


For example, to query for all resources where the value of a specific property is greater than 50:

1
2
3
4
5
SELECT ?subject
WHERE {
  ?subject <http://example.org/property> ?value .
  FILTER (?value > 50)
}


You can combine multiple FILTER clauses and triple patterns to create more complex queries to query for specific values in your RDF data.
