Identification/Codification Standards

S25-1G Data Constructs for the Communication of Information on Postal Items, Batches and Receptacles

Introduction This standard is presented using two basic styles and font sizes. Paragraphs in 12 point Century Schoolbook (like this one) form part of the standard. Paragraphs which are indented, shaded, with a border at the left and in 10 point Century Schoolbook provide explanatory notes, examples and justification of the choices made in the definition of the standard itself.

This is a note; like other note paragraphs it is provided as an illustration and is not normative.

The standard described in this document is incomplete in several respects:

• it defines only a small number of Data Constructs, in particular those identified as being of key importance to RFID and Proof of Payment applications
• it lacks formal ASN.1 specifications of the Data Constructs
• it lacks, or has only provisional values for, FACT Data Identifiers and S24 Format Identifiers used in FACT representations
• it lacks, or has only provisional details of, ASN.1 PER encodings.

The present document serves to document the status of the development of Data Construct Definitions and to provide parties interested in the subject matter with information on the approach being taken by the working groups responsible for the development of standards in the two application areas identified. Readers are encouraged to submit comments and eventual requests for the definition of additional Data Constructs back to the working groups. This may be done via the Secretariat of the UPU Technical Standards Board.

Use of the present version of the standard as a basis for any implementation is at the risk and for the account of the user. Any party intending such use is strongly advised to seek close contact with the appropriate working group, so that it can be kept informed of ongoing work.

Scope: This standard provides a dictionary of Data Constructs for use in the communication of information about postal items and batches. It is a subsidiary standard to S27: Communication of Information about Postal Items, Receptacles and Batches, which defines an overall Framework for such communication.

Companion standard S27 defines an overall Framework for the communication of information about postal items and batches. It introduces the concept of such communication taking place through the sending of Messages, each of which has a content consisting of one or more Data Constructs.

This standard defines the Data Constructs which can be used.

The standard is largely composed of a series of Data Construct Definitions, arranged in alphabetical order.

For each Data Construct which is defined, the standard provides a definition, one or more examples of its application, a specification of the logical data content and value range, and details of any constraints on its use.

Each definition also provides a specification of the way(s) in which the data should be encoded using data representations, other than in EDI Messages, supported by the Framework standard.

S27 supports a variety of media and methods of communication, ranging from encoding on items or accompanying documents, through physical exchange of computer files on magnetic and other media, to the use of telecommunications.

The various approaches supported are defined in subsidiary standards, such as S28: Communication of Postal Information using Two-Dimensional Symbols for encoding in two-dimensional symbols and S24: FACT-Based Representation of Postal Information and Identifiers for FACT-based encoding in linear bar-codes.

The way in which data are represented is to some degree dependent on the communications approach used. This standard therefore details the encoding for each of the supported approaches.

It does not cover EDI Message representation, because this is covered in a separate manual, the UPU Message Development Guide.

The standard does not specify rules and procedures for data validation. These may depend on particular applications and operational procedures and are left to the discretion of users.

Allowance shall be made for the fact that the actual data contained in Messages, whether encoded on items or sent electronically or otherwise, may be:

incorrect and / or inconsistent with other data about the same item(s) or receptacle(s).

For example:

address data may be incorrect or incomplete

requested services may be incompatible with other attributes, e.g. a "deliver by" date may precede the actual date of mailing different instances of the same data may be inconsistent, e.g. the delivery postcode in an indicium may differ from that in the human and OCR readable delivery address.

Appropriate measures should be taken to detect and respond to such errors and inconsistencies, but these measures fall outside the scope of this standard.

The standard is a dynamic one, subject to extension as requirements for new Data Constructs, or for new representations, are identified.

Users of the standard requiring definitions for new Data Constructs, or definitions of as yet incomplete representations should consult the secretariat of the Technical Standards Board for more information.

The present version of the standard contains only those Data Construct definitions and representations which are required by currently intended applications. As new applications are developed, the requirement for new Data Constructs and new forms of representation will inevitably arise. It is intended that the standard will be extended to accommodate these. The TSB secretariat can provide both information on as yet unpublished developments and assist in ensuring that new requirements are brought to the attention of the working group responsible for development and maintenance of the standard.

S23-1 Part B Radio Frequency Identification (RFID) and Radio Data Capture (RDC) Systems

Air Interfaces : Communications and Interfaces :Part B : Parameter Values for 5.8 GHz RFID Systems

Introduction: This is part of a series of Standards defining Identification /Codification Standards for the UPU, for use in RFID and RDC systems.

Part A of this Standard (Parameters), identifies which Parameters it is necessary to determine to establish interoperability, and provides common methods of determination and description.

Subsequent parts of this Standard will provide value definitions for each of the approved world wide frequencies, and may also, where appropriate, provide regional definitions with geographical constraints.

This part, Part B, Determines Parameter Values for 5.8 GHz Narrow Band RFID Systems. The Standard is to be read in conjunction with S23 Part A.

Scope: The Scope of this Standard is therefore to establish the values and value ranges associated with the Parameters to be Standardized for RFID Systems at 5.8 GHz. In order to claim compliance with this Standard, a system shall operate to the protocols and procedures defined in Standards S-20, S-21, and S23, and shall operate within the values and value ranges defined herein. This Standard limits its scope to the interface at Reference point Delta (Air interface between Transponder/OBE and reader).

S23-1 Part C Radio Frequency Identification (RFID) and Radio Data Capture (RDC) Systems

Air Interfaces : Communications and Interfaces :Part B : Parameter Values for 2.45 GHz Narrow Band RFID Systems

Introduction: This is part of a series of Standards defining Identification /Codification Standards for the UPU, for use in RFID and RDC systems.
