use entities found in schema, not in the etypes registry, else we miss entity types which have no specific classes
class Personne(EntityType):
nom = String(required=True)
prenom = String()
type = String()
travaille = SubjectRelation('Societe')
evaluee = SubjectRelation(('Note', 'Personne'))
connait = SubjectRelation('Personne', symetric=True)
class Societe(EntityType):
nom = String()
evaluee = SubjectRelation('Note')
class Note(EntityType):
type = String()
ecrit_par = SubjectRelation('Personne')
class SubNote(Note):
__specializes_schema__ = True
description = String()
class tags(RelationDefinition):
subject = 'Tag'
object = ('Personne', 'Note')
class evaluee(RelationDefinition):
subject = 'EUser'
object = 'Note'
