SDC should follow standard URI pattern for RDF dumps, but it does not.
Currently, wikidata's data and entity URI prefixes look like this:
```lang=turtle
@prefix wd: <http://www.wikidata.org/entity/> .
@prefix data: <https://www.wikidata.org/wiki/Special:EntityData/> .
```
Currently sdc has those prefixes.
```lang=turtle
@prefix sdc: <https://commons.wikimedia.org/wiki/Special:EntityData/> .
@prefix sdcdata: <https://commons.wikimedia.org/wiki/Special:EntityData/> .
```
With other prefixes build upon data prefix (or, as always, on entity prefix, but here they are identical).
sdc should be similar to wikidata:
```lang=turtle
@prefix sdc: <https://commons.wikimedia.org/entity> .
@prefix sdcdata: <https://commons.wikimedia.org/wiki/Special:EntityData/> .
```
Note that other URI prefixes should follow suit. e.g. reified statement should be entity + "statement/".
NT dumps are also affected.
