exemplified by paper tags.

The result of the whole mapping of the RFID logistics scenario, for only the
pallet plus everything it contains, is depicted in Figure 88.

Figure 89 : Domain modelling of a typical EPC-based RFID scenario (pallet containing

cases).

In this example, the Virtual Entities take the form of database records (Figure
89 ) stored in a Network Resource, the EPC Database. This database is
