It says deprecated on the Data model wiki.
So maybe Wikidata doesn't need statement-level granularity? Maybe the named
graph approach is good enough? But it's not based on statements.
If you build this kind of data model on the relational, not to mention
provenance, you will not be able to
You do not need the full expressive power of SPARQL or graph
querying -- what kind of query mechanism is Wikidata planning to
support in later stages? I don't suppose the data model will be
redesigned for that? So in that case you have to have queries in mind
from the start of its design.
