rschema: relation_schema
eschema: entity_schema
subschemas: subject_schema
subjeschemas: subject_entity_schema
objeschemas: object_schemas
objeschema: object_schema
subjschema: subject_schema
subj: subject_entity
obj: object_entity
objtypes: object_types
objtype: object_type
subjtype: subject_type
msg: message
rdef: relation_definition
attr: attribute
prop: property_
propdefs: property_definitions
etype: entity_type
cstr: constraint
