**Current Situation:**
- Wikibase Suite instances uses the same prefixes as wikidata in sparql
- This collides when federating with wikidata
```
prefix wd: <http://www.wikidata.org/entity/>
prefix wdt: <http://www.wikidata.org/prop/direct/>
SELECT ?item ?itemLabel
WHERE
{
SERVICE <https://query.wikidata.org/sparql> {
?item wdt:P31 wd:Q146.
?item rdfs:label ?itemLabel.
FILTER(LANG(?itemLabel) = "en").
}
}
```
**Goal:**
- define custom prefixes for the instance (in `.env`?) to not collide with wikidata and allow easy federation with wikidata and local prefixes
**Acceptance Criteria:**
[] users can define their custom prefixes
[] federation with wikidata can be easily done in sparql using wikidata and local prefixes
[optional] **Notes:**
- `ldf-config.json` in wdqs might be something to look out for
