Problem:
Looking at https://wikiba.se/ontology, the following property datatypes are missing (example query):

• wikibase:WikibaseLexeme
• wikibase:WikibaseForm
• wikibase:WikibaseSense
• wikibase:EntitySchema

The following predicate is also missing (example query):

• wikibase:directClaimNormalized

The AllDisjointClasses section has wikibase:Form but not wikibase:Sense.

Acceptance criteria:

• the ontology files inthe source code repos are updated (note: you might need to add a new ontology file to the EntitySchema extension since it doesn't have one yet)
• the missing datatypes are defined in https://wikiba.se/ontology
• the missing predicate is defined in https://wikiba.se/ontology
• wikibase:Sense is added to the AllDisjointClasses section in https://wikiba.se/ontology

[ ] Lydia has found the checklist for adding a new datatype and makes sure updating the ontology file is included in the checklist

Additional info:

• The Wikibase Suite team can upload a new ontology file to https://wikiba.se
