The MetaHeritage Business Cases Deliverable (D5.2) presents a portfolio of four interregional businessconcepts and it provides the strategic and operational framework for translating the evidence collected inWP2 into concrete, market-oriented ideas that connect cultural and corporate heritage, digitaltechnologies and smart tourism within a shared interregional innovation logic.The business cases are developed through an evidence-based approach and ongoing dialogue withproject partners, regional actors, and potential supporting organisations. This ensures that the proposedconcepts respond to real ecosystem gaps and market opportunities, rather than remaining purelyconceptual.
