Today, industrial production and supply chains are facing increased demands regarding flexibility and transparency of processes, caused by a trend for mass-customization and increasingly tighter regulations for the traceability of goods. To fulfill such challenging market demands, auto-ID technologies and semantic product descriptions are becoming part of future value chains. In this paper a modelling approach for a digital object memory (DOM) allowing for the attachment of product life cycle (PLC) information to everyday objects is presented. After reporting on the design aims, memory architecture and data structure, potential benefits of the chosen approach are presented.
