That hyphen, although well-intentioned, was wrong. DPD is not definition of a digital product. It is product definition that is digital (rather than by engineering drawing).
'''Model-based definition''' ('''MBD'''), also known as '''digital product definition''' ('''DPD'''), is the practice of using [[3D modeling|3D models]] (such as solid models, 3D [[Product and manufacturing information|PMI]] and associated metadata) within 3D [[computer-aided drafting|CAD]] software to define (provide specifications for) individual components and product assemblies. The types of information included are [[geometric dimensioning and tolerancing]] (GD&T), component level materials, assembly level [[bill of materials|bills of materials]], engineering configurations, design intent, etc. By contrast, other methodologies have historically required accompanying use of 2D [[engineering drawing]]s to provide such details. The general category of '''digital product definition''' ('''DPD''') can be either [[synonym|synonymous]] or [[hyponymy and hypernymy|hypernymous]] with model-based definition; it comprises all product definition that is [[digital data|digital]], which usually includes a 3D model (and thus MBD).
