PD CEN/TS 16735:2015CEN/TS 16735:2015 (E) 5 Introduction Standards are important prerequisites for effective postal operations and for interconnecting
20、the global network. Significant efficiency can be gained by implementing standards that define interconnectivity between postal operators and their customers. The postal sector is now facing the most challenging period in its long history. On the one hand, up to a few years ago the postal sector in
21、its letter mail market has not faced competition from new entrants as a result of the historic reserved areas and letterbox monopoly. On the other hand it is confronting formidable competition from outside of its traditional boundaries (this type of competition is frequently referred to as “electron
22、ic substitution” or “electronic diversion”). One of the most effective responses to competitive pressure is innovation. Innovation involving an extensive use of modern information technology has proven to be particularly effective in many fields. However, information technology, while deeply permeat
23、ing many aspects of the postal system, still lacks significant penetration when it is applied to postal product innovation, marketing and distribution. To alleviate this shortcoming UPU in collaboration with CEN/TC 331 developed and published the standard UPU S54. This standard is aimed at making a
24、significant step forward in enabling more effective use of information technology in these areas. The standard however does not fully address effective computer-aided management of postal rates by both postal operators and their customers. This Technical Specification has been developed to provide p
25、ostal operators, carriers, their customers and mailing industry at large with a tool designed for computerized creation, management and distribution of postal rates. Mail communication involves a complex process of mail item production, induction, processing, transportation and delivery. It consists
26、 of a sequence of information and physical activities. The physical activities (required for mail item production, induction, sort, transportation and delivery) are supported by information processing activities that play an increasingly important role in the overall system. Complexity of the mail c
27、ommunication system also stems from the fact that different processes and activities (both physical and informational) are performed by different parties that are only loosely integrated and thus generally do not make optimal use of available information. In order to achieve a higher level of integr
28、ation and better meet increasingly demanding requirements of customers, the mail communication system requires that different parties, entities and processes within the system should be integrated together via a set of standardized interfaces. One of the most important interfaces is the set of rates
29、 for postal products. This is viewed in this Technical Specification as an information interface between posts (postal operators) and their customers, both mail senders and mail recipients. More specifically, from an information viewpoint, postal rates are data files that are created and managed by
30、postal operators and carriers and distributed/shared with their customers. By defining postal rates using a computerized description resulting in a standardized electronic document (postal rate file), postal operators can enable its customers to more effectively review and choose products suitable f
31、or their communication needs as well as provide for automated computing and application of postal rates during mail generation and finishing process. The criteria that the postal rate file (as an information object) should meet are completeness, non-redundancy, consistency and unambiguous interpreta
32、tion by mailers equipment. In order to meet these criteria it is necessary to make rate information communications and processing computerized and automated, thus achieving ubiquity, consistency, speed and error tolerance typical for internet-based information exchanges. This Technical Specification
33、 is an information description and presentation document. It is intended as a powerful and flexible tool capable of supporting both human and machine descriptions of postal rates with arbitrary complexity. In accordance with this Technical Specification, postal rate data files are messages that are
34、structured in accordance with a specialized data representation language named Extensible Common Structure and Representation for Postal Rates (EPR). The EPR is organized as an application-specific version of the XML. It consists of flexible and adaptable constructs (elements) and thus by its very d
35、efinition is extensible. PD CEN/TS 16735:2015CEN/TS 16735:2015 (E) 6 The EPPML standard (UPU S54-2) only briefly touches postal product prices (postal rates) and their use and communication. It defines rates communication by post and their acquisition by postal customers in a flexible manner leaving
36、 all technical details and structures of rate data outside of its scope. This Technical Specification is aimed at filling this gap. Postal operators, their suppliers, mailing industry and mailing community at large developed many ad hoc rates structures and communication mechanisms designed to work
37、in specific postal environments. In many instances the process of creating, updating and communicating postal rates (tables) is costly and time- consuming while there is a growing need to have fast (e.g. at the speed of the internet) distribution of rates and rate updates from postal operators to th
38、eir customers (mailers and in some instances also mail recipients). Traditional methods as they are practiced today by a vast majority of postal operators involve distribution of postal rates to customers via physical documents or electronic documents that are not designed for automated interpretati
39、on and processing by computers. In case of commercial mailers who mail from tens to millions of mail unit per day this results in a manual process of rate data translation into data structures suitable for computer processing by mail generation and finishing equipment. This process is most frequentl
40、y performed by trained professionals employed by the mailing industry (typically manufacturers of just mentioned mailing equipment), at a large cost and inconvenience to mailers and postal operators. However, an examination of postal rate data (typically rate tables) and their communication mechanis
41、ms as practiced by a majority of technically advanced postal operators revealed mostly common structure, features and approaches. This suggests that there has to exist a common, flexible and extensible data structure suitable for use as a basis for automated postal rate management and communication
42、in all mailing environments, from SMEs to large enterprises. Modern general data representation language such as XML can be adapted for the purpose of defining such a structure, which is referred below as the Extensible Common Structure and Representation for Postal Rates or the EPR. This Technical
43、Specification presents detailed and practical description of the EPR while leaving decisions and implementation of actual postal product pricing (e.g. valuation) to postal operators, their regulators (if any) and the mailing industry. Postal operators and mailing industry can use this Technical Spec
44、ification, as a guidance document for the development of their own software tools that, when implemented, will allow quick and cost effective postal rate management process. This Technical Specification should be viewed by postal operators, their suppliers and mailing industry at large as a valuable
45、 data representation standard and a tool that will facilitate all stages of postal rates life-cycle processing and management from creation by postal operators to installation and use in customer mailing equipment and ultimate disposal. “Postal products” are referred to below simply as “products”. T
46、he reader is referred to the UPU S54 standard for detailed discussion and definition of various aspects and attributes of postal products. Postal products are always associated with postal rates, which is a specific established term for postal product prices. When a class of the mail unit (i.e. lett
47、er, flat or parcel) is not mentioned it usually implies any suitable class. This Technical Specification uses the established definition and terminology for the “mail unit” as a physically constrained unit consisting of one or more mail items and/or lower level mail units, together with the means of
48、 constraint (as defined in the UPU Standards glossary). The terms “mailer” and “sender” are used interchangeably. The notion of the postal product is a complex one. Unlike common products (food, clothing, books), that are bought and consumed every day, postal product consumption requires significant
49、 cooperation between product producers (postal operators and carriers) and consumers (mailers and recipients). An important part of cooperation involves computation of the rate for a postal product that is to be paid to a postal operator offering this product for sale. This computation is commonly known as a “rating” or “rating process” and most frequently performed during mail unit generation and finishing process that takes place in a mailers environment (this is due to prepayment requirement imposed by majority of postal operators or simply because of a need of
