ePO

The ePO subset is based on the eProcurement Ontology (ePO), which models public procurement processes in the European Union.

Domain

The ePO covers multiple stages of the procurement lifecycle, including ordering, invoicing, and payment. The shapes specify constraints on entities and relationships across these stages, resulting in a wide variation in complexity.

Constraint patterns in this subset include:

  • Entity and relationship constraints across procurement stages
  • Wide variation in constraint complexity
  • Cross-stage validation dependencies

Additional filtering and sampling were applied to this subset to ensure balanced and tractable descriptions.
