DHRM: A new model for PLM dedicated to product design heritage

Cultural heritage is often considered to be a social duty, rather than an economic opportunity. Enterprises do not consider their own heritage because studying and capitalizing ancient know-how is too complex. The main problem is that digitizing old objects required specific methodology with dedicated tools and competences. Consequently, museums are the core centre for conserving inert old objects. A scientific proposition is a framework coupled to a multi-business information system: the Digital Heritage Reference Model. This new PLM is based on a product-process approach adapted to manage historical knowledge for cultural heritage. A new modelling language has been defined to support spatio-temporal problematics and human beings. A use case will demonstrate our contribution. Thanks to advanced technology, users can interact with linked heterogeneous data such as semantics, geometry, and temporal information. (C) 2015 CIRP.
