Hello,
You can find it here: http://wikiba.se/ontology-1.0.owl
If you have questions regarding the ontology, feel free to ask.
Please note that this is the *wikibase* ontology, which thefines the meta-model for the information on Wikidata. It defines models statements, sitelinks, source references, etc.
This ontology does not model "real world" concepts or properties like location or color or children, etc. Modeling on this level is done on Wikidata itself, there is no fixed RDF or OWL schema or ontology.
The best you can get in terms of "downloading the wikidata ontology" would be to download all properties and all the items representing classes. We currently don't have a separate dump for these. Also, do not expect this to be a concise or consistent model that can be used for reasoning. You are bound to find contradictions and lose ends.
