A digital object memory (DOMe) is a digital storage space intended to keep permanently all related information about a concrete physical object instance that is collected during the lifespan of this object and thus forms a basic building block for the Internet of Things (IoT) by connecting digital information with physical objects.
Such memories require each object instance to be uniquely identified and this ID to be attached to the physical object. The underlying techniques to create identification codes and to attach them to objects are manifold but machine-readable techniques are mandatory. Commonly used are barcodes with one or two dimensions (e.g. QR code or Data Matrix) and radio based tags like RFID or NFC. Such codes or tags are a low cost solution but demand an underlying server infrastructure to host the memory data.
Active digital object memories
In contrast to the mentioned memories providing only a passive storage space, the more sophisticated active digital object memories (ADOMe) are based on embedded systems in terms of cyber-physical systems (CPS) and provide on
