scope:

This International Standard defines an interface within the Software System Infrastructure (SSI) that provides RFID system control components with low-level access to RFID interrogators for the purpose of optimizing RFID data access and control operations. This interface is designed to be modular with the ability to support multiple RFID air protocols. In this International Standard edition, however, the only RFID air protocol supported is Type C of ISO/IEC 18000-6. The interface defined by this International Standard supports the following features: - efficient, binary transfer syntax over TCP/IP - access to RFID air protocol commands and command parameters - support for optimized RFID tag access operations whereby multiple operations can be performed on a tag with minimal tag state changes - direct read/write access to all data on an RFID tag - read one or more individual tag data items (encoded as defined by ISO/IEC 15962) as specified by their OID using URN notation - [optional] decode data items (encoded as defined by ISO/IEC 15962) into their Unicode representation (UTF-8 encoded). Encoding data items is not supported. - support for RFID air protocol type defined by Type C of ISO/IEC 18000-6 The interface defined in this International Standard provides access to RFID air protocol commands and their respective command parameters. Therefore using this interface, tag memory banks can be locked, tags can be killed, and raw-binary RFID tag data can be accessed directly on a tag for both reading and writing. In addition, individual data items (encoded as defined by ISO/IEC 15962) can be read by specifying each data item's OID. Optionally, the interrogator can decode data items read into their character string representation. If the interrogator cannot decode a data item, then it will return the entire encoded package within which the data item resides. In this case, it is the responsibility of higher-level software to further decode the data item. The interface does not support RFID tag data encoding. It is the responsibility of higher-level software (i.e., software outside the interface defined by this International Standard) to perform data encoding (i.e., binary tag data representation as defined by ISO/IEC 15962) that is stored on RFID tags. This Part of this International Standard is composed of the EPCglobal(TM) standard, Low Level Reader Protocol [LLRP], in its entirety with extensions that support reading RFID tag data items that are encoded according to ISO/IEC 15962. As does the LLRP standard, this International Standard defines both the abstract functional capabilities of the interrogator interface and the binary transfer syntax between the interrogator and a controlling system device. The transfer syntax is defined to be communicated over TCP/IP.
