"Implement** if needed** const OPT_GROUP_BY_PROPERTIES = 'groupByProperties'; " https://github.com/wmde/WikibaseDataModelSerialization/issues/50

Grouping by property ID should be applied to: * Statements * Qualifiers * Reference Snaks Perhaps grouping should always be applied; in that case, the ungrouped structure should still be accepted as input. Note: The grouped structure is better for access by property. The an ungrouped list map of statements is better for access by GUID. https://github.com/wmde/WikibaseDataModelSerialization/issues/50
