Linking of data structure definitions to vocabularies

Summary
In cases where external vocabulary terms are not suitable for direct reuse in data structure definitions, while being semantically related, they may be interlinked with internal vocabulary terms. Such mappings will determine relations to external RDF vocabularies and ontologies and hence contribute to alignment with external data. These links will make it easier to integrate OpenBudgets.eu datasets with third party data and applications. Links of data structure definition components will be created and curated manually, due to their small size and high quality that is required of them.
