Physical Mark-Up Language Update

The objective of this briefing is to give an overview of the efforts to 
develop a Physical Mark-up Language (PML). The main goal of the Physical 
Mark-up Language is to provide a common, standardized vocabulary to represent 
and distribute information related to Auto-ID enabled objects. In this 
document, the types of information modeled in this vocabulary and their main 
usage scenarios are discussed. This brief also describes the division of the 
development effort into a PML Core component and a PML Extension component. 
The former focuses on developing a vocabulary to model the data directly 
generated by the Auto-ID infrastructure - such as location and telemetry 
information. The work related to the PML Extensions leverages existing 
developments in the world of e-commerce standards to combine the low-level, 
instance-specific Auto-ID generated data with high-level product- and 
process-related information.
