This part of ISO/IEC15961 focuses on the abstract interface between an application and the data processor, and includes the specification and definition of application commands and responses. It allows data and commands to be specified in a standardised way, independent of the particular air interface of ISO/IEC18000.
This part of ISO/IEC15961
provides guidelines on how data shall be presented as objects;
defines the structure of Object Identifiers, based on ISO/IEC9834-1;
specifies the commands that are supported for transferring data between an application and the radio frequency identification (RFID) tag;
specifies the responses that are supported for transferring data between the RFID tag and the application;
does not specify any required transfer syntax with ISO/IEC15962, but provides the non-normative information in AnnexA to provide backward compatibility with ISO/IEC15961:2004.
It is expected that this part of ISO/IEC15961 will be used as a reference to develop software appropriate for particular applications, or for particular RFID equipment.
