# Federated query to rdflib-endpoint
To test it locally start the docker compose stack in this folder
## Test locally
Need to use the host from the docker network:
```sparql
SELECT * WHERE {
SERVICE <http://rdflib-endpoint/> {
SELECT ?o WHERE {
?s ?p ?o .
}
}
}
```
Local with FILTER:
```SPARQL
SELECT * WHERE {
SERVICE <http://rdflib-endpoint/> {
SELECT ?o WHERE {
VALUES ?s { <http://subject> }
?s ?p ?o .
}
}
}
```
Test on bioregistry simple:
```SPARQL
PREFIX owl: <http://www.w3.org/2002/07/owl#>
SELECT * WHERE {
SERVICE <https://bioregistry.io/sparql> {
<http://purl.obolibrary.org/obo/CHEBI_1> owl:sameAs ?o
}
}
```
Test on bioregistry with values:
```SPARQL
PREFIX owl: <http://www.w3.org/2002/07/owl#>
SELECT * WHERE {
SERVICE <https://bioregistry.io/sparql> {
VALUES ?s { <http://purl.obolibrary.org/obo/CHEBI_1> }
?s owl:sameAs ?o
}
}
```
## ✅ Working
- Qlever: https://qlever.cs.uni-freiburg.de/uniprot/
- Virtuoso: if not using VALUES in service call
- Oxigraph
- GraphDB (fixed at last release)
- Blazegraph
- Fuseki
## ❌ Not working
- MilleniumDB
