22、09CEN/TS 15873:2009 (E) 4 1 Introduction In initial meetings of CEN/TC331/WG3 interfaces which will benefit from standardization have been identified and agreed on. Candidates for Open Interface standardization are: interface between the image handler and automatic address readers or video coding pl

23、aces; interface from machine control to Barcode Printers; interface from machine control to Barcode Reader / Verifier; interface between scanner, image handler and machine control; file format of Sort Plan; MIS Interface (Statistics); file format of Address data files. The new intended standard deal

24、s with the file format of Address Data Files. OCR results and video coder inputs have to be verified against the “real” existing addresses in order to reach high recognition rates combined with low error rates. For that purpose postal operators provide postal address directories to the OCR/VCS suppl

25、iers. Usually different postal operators use different file formats for these (source) directories. In typical postal automation systems these files will be processed by directory generation software which creates application specific loadable data. This data usually referred to as “operational dire

26、ctory” is heavily compressed and contains access tables tailored for the specific reading software. Usually different OCR/VCS suppliers use different operational directory formats. This standard shall define a common Address Data File format for postal address directories to be provided from the pos

27、tal operators to the OCR/VCS suppliers. This Address Data File format shall be designed to hold all information necessary to support address reading and video coding software including data required for special recognition tasks e.g. forwarding applications.

It is designed to hold all information necessary to support address reading softwa

29、re including data required for forwarding applications. In typical postal automation systems these files will be processed by directory generation software which creates application specific loadable data. This data usually referred to as operational directory is heavily compressed and contains acce

30、ss tables tailored for the specific reading software. Not in the scope of this document are topics external to file like compression, checksums, the interface for transmission to the supplier, modification permissions, error handling on inconsistent data and undo in updates. 2.2 Purpose The format h

31、as been designed with the following requirements in mind: must be able to hold the following data: addresses composed of address components (including aliases and range-data); person and organization names; address codes typically used as sort codes; links between addresses e.g. for use in forwardin

32、g; should not restrict character encoding; easily customizable for specific applications; should allow complete as well as incremental updates, i.e. change-only data; it must be possible to split data in multiple files for better handling. The ideas behind this format are as follows: The format is b

33、ased on XML. The basic XML structure is general. Project(the term project is used throughout this document to describe a specific application such as address data for a specific country or postal organization) specifics are coded as attributes. This should make it easier to build project independent

34、 parsers and tools. Address data can be structured hierarchically. An address component appearing in a lot of addresses shall be written once as parent node in all addresses it is used in the XML address tree. Beyond the pure address data, there are general as well as optional project specific attri

35、butes on the level of address components and string parts. In favour of faster parser execution and smaller file sizes the names of XML elements appearing very often are short strings.

36、2009CEN/TS 15873:2009 (E) 6 Semantics are defined only in a basic manner and have to be completed in the project specific tailoring process. E.g. a street without numbers in the data may be interpreted as a street which has no numbers, or where all numbers are valid. Due to this users must be aware

37、that the interoperability of this Technical Specification may be limited to be applied to the specific project.

38、 beginning with version -5 a two part standard. Part a contains concepts and the theoretical language description. Part b contains practical examples from different countries and may be supplemented with new examples in some future. 2) UPU S42a defines components an address is composed of as well as

39、 postal entities which can be “described” using these address components. The standard goes into great detail in defining a globally usable set of specific address components such as “postcode”, “door”, . 3) UPU S42b describes how to write an address given its constituting address components. It use

40、s templates to describe the order, line-breaks, etc. The templates are country specific (US, Brazil, England, .) and also uses an country specific subset of the globally defined types. 4) UPU S42 address components are assumed to have a type and a string. They do not have additional attributes and d

41、o not have aliases. 5) UPU S42 does not define a format for an individual address = address-component collection and does not define a format for an address directory = set of addresses. 6) UPU S42 has no concept of sort codes or forwarding information. UPU S42 will not conflict with the format defi

42、ned in this document as it targets at a completely different application and type of information described. The only thing in common with address data are the address-component definitions themselves. These could be used in customizing the ADF for a specific project. UPU S42s excellent glossary shou

43、ld be reused where applicable. 4 Symbols and Abbreviations XML eXtended Markup Language ADF Address Data File Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 15/04/2010 03:34, Uncontrolled Copy, (c) BSIDD CEN/TS 15873:2009CEN/TS 15873:2009 (E) 8 5 XML Schema adressTree The syntax is described

44、 as an XML schema, divided into a general and a project specific part. The general part of the XML Schema defines the basic structures. It uses some types and attribute groups to be defined in the project specific part. Basically the structure spans a tree of address components represented by XML el

45、ements . The general part of the schema is listed in section A.1A.1. The project specific part is explained in section 5.9. This document contains also another XML Schema addressDeltaTree explained in chapter 6. The following Figure 1 shows the general structure of the XML schema. Since the project

46、specific part does not change the general structure the diagram is independent from any project specifics.

47、5.1 , and Below the XML root element is one and one section. The stores a string and optionally a list of global aliases. Aliases are described in section 5.6. A version string of the data contained in the file is stored in the element. 5.2 Address Tree in , and Addresses are stored in an address tr

48、ee corresponding to the XML elements , and . is the root node of this tree, address components stored in are the nodes and may be additional leafs. Explanation on the element follows in section 5.8. One complete address corresponds to one leafs root path. Each nodes root path identifies a partial ad

49、dress. Other XML elements and attributes carry additional information for the address tree node. allows to split data into multiple files. One address component in XML element holds a type mentioned in attribute tp and a string in child elements or and . Attribute tp and other optional attributes for are described in section 5.3. Other optional child elements are described in the following sections. In this context one address component holds just a name with
