I have a sandbox project here https://github.com/kinow/jena-arq-filter, not
really unit tests, but some renamed main methods that I use for experimenting.
You can try checking out this pull request, opening in the same workspace both
projects, then trying something like this:
```
// Query String
final String queryString = "PREFIX skos:
<http://www.w3.org/2004/02/skos/core#>\n" +
"PREFIX arq: <http://jena.apache.org/ARQ/function#>\n" +
"SELECT ?label WHERE {\n" +
" VALUES ?label { \"tsahurin kieli\"@fi \"tšekin
kieli\"@fi \"tulun kieli\"@fi \"töyhtöhyyppä\"@fi }\n" +
"}\n" +
"ORDER BY arq:collation(\"fi\", ?label)";
// --- Model
Model model = ModelFactory.createDefaultModel();
// Query object
Query query = QueryFactory.create(queryString);
// Execute query
try (QueryExecution qExec = QueryExecutionFactory.create(query,
model)) {
ResultSet results = qExec.execSelect();
while (results.hasNext()) {
QuerySolution solution = results.nextSolution();
System.out.println(solution);
}
}
```
The result will be:
```
( ?label = "tsahurin kieli"@fi )
( ?label = "tšekin kieli"@fi )
( ?label = "tulun kieli"@fi )
( ?label = "töyhtöhyyppä"@fi )
```
If you change the locale for "en", then it will be:
```
( ?label = "töyhtöhyyppä"@fi )
( ?label = "tsahurin kieli"@fi )
( ?label = "tšekin kieli"@fi )
( ?label = "tulun kieli"@fi )
```
