18、EN 13710:2011 (E) 4 Introduction This European Standard provides rules for ordering multilingual lists into a well-defined and intuitive sequence. These rules are intended for data from different European languages that must be brought into a predictable order that makes it easy for users from multi
19、ple cultural backgrounds to find information. At the same time the standard is a basis for the definition of language-specific profiles taking the rules of a given language community into account at the same time as the total pan-European character set in a consistent, pan-European manner. The rules
20、 have been tested and widely adopted in two predecessor specifications, ENV 13710:2000 European Ordering Rules Ordering of characters from the Latin, Greek and Cyrillic scripts and its companion and extension specification CR 14400:2001 European Ordering Rules - Ordering for Latin, Greek, Cyrillic,
21、Georgian and Armenian scripts. This European Standard consolidates these two documents into one technically largely upwards compatible standard. This European Standard caters for two different target groups, software implementers on the one hand and users of ordering applications on the other. Softw
22、are implementers need unambiguous, machine-processable guidelines, which can readily be loaded into existing and future ordering applications. This goal can best be achieved by defining a european default ordering table in the syntaxes of two internationally relevant specifications in the field: the
23、 international ordering standard ISO/IEC 14651:2007 International string ordering and comparison Method for comparing character strings and description of the common template tailorable ordering, of which the present standard is a “delta“ (Clause 6); the Locale Data Markup Language (LDML) which is u
24、sed to capture (amongst others) the collation data for the Unicode Common Locale Data Repository (CLDR). CLDR builds on the Unicode Collation Algorithm (UCA) which is technically a profile of ISO/IEC 14651:2007 (informative Annex G). Users with no specific ICT background, however, need an explanatio
25、n of the principles in a form more in line with existing national ordering standards or relevant practice. Tailoring tables can be difficult to read for human readers, so an explanation of the principles behind that table is given in the informative annexes. Users not familiar with the formal syntax
26、 of the tailoring table are advised to consult those annexes first. The normative main part of this European Standard specifies letter-by-letter ordering of character strings. Informative Annex A presents equivalent information in a more human-oriented way. Informative Annex B deals with word-by-wor
27、d ordering as a special form of ordering with multiple keys. Informative Annex C explains the use of further ordering criteria. Informative Annex D presents a widely used alternative to the main part, namely the amalgamation of several scripts in one index via implicit transliteration. Informative A
28、nnex E gives guidance on the use of this European Standard as the basis for expressing national deltas. Informative Annex F lists the underlying character repertoire for ease of reference. Informative Annex G expresses the formal delta in the LDML syntax. Following the practice of ISO/IEC 14651 char
29、acters are referenced as UXXXX where X stands for any hexadecimal digit and refers to the code position of that character in ISO/IEC 10646. This convention is used throughout this European Standard. BS EN 13710:2011EN 13710:2011 (E) 5 1 Scope This European Standard specifies the order between two ch
30、aracter strings composed of characters from the Modern European Scripts (MES) collection of ISO/IEC 10646:2003 or subsets of it. NOTE Collection 283 Modern European Scripts (MES) of ISO/IEC 10646:2003 was originally specified in CEN Workshop Agreement 13873:2000 Multilingual European Subsets of ISO/
31、IEC 10646 as Multilingual European Subset Number 3 and was subsequently incorporated as a collection in Annex A of ISO/IEC 10646:2003 alongside its sister collections MES-1 and MES-2. The ordering rules specified in this European Standard are only applicable for lists of data in more than one Europe
32、an language and when this data is intended for a multicultural audience. They complement existing national standards or practices in the field. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cit
33、ed applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

35、s and definitions of ISO/IEC 10646:2003 and of ISO/IEC 14651:2007 apply. 3.1 character member of a set of elements used for the organisation, control, or representation of data ISO/IEC 10646:2003 3.2 character string sequence of characters considered as a single object ISO/IEC 14651:2007 3.3 collati
36、ng symbol symbol used to specify weights assigned to a collating element ISO/IEC 14651:2007 3.4 collating element sequence of one or more characters that are considered a single entity for ordering ISO/IEC 14651:2007 BS EN 13710:2011EN 13710:2011 (E) 6 3.5 collation table mapping from collating elem
37、ents to weighting elements ISO/IEC 14651:2007 NOTE A special collation table is the Common Template Table (CTT) used in Annex A of ISO/IEC 14651 to express the default mapping from collating elements to weighting elements. 3.6 delta list of the differences between a given collation table and another
38、 one ISO/IEC 14651 NOTE The given collation table, together with a given delta, forms a new collation table. Unless otherwise specified in the European Standard, the term “delta“ always refers to differences from the Common Template Table as defined in ISO/IEC 14651. 3.7 ordering process by which, g
39、iven two strings, it is determined whether the first one is less than, equal to, or greater than the second one ISO/IEC 14651:2007 3.8 sorting presentation of information in a structured way NOTE Sorting may include the subdivision of information by subject matters, e.g. by having several registers
40、in a book, by splitting a phone book into several sections, one for each town that falls into its purview or by having multiple indices in a library. Ordering is in most circumstances an integral part of this procedure. 4 Conformance In order to be conformant to this European Standard an application
41、 shall meet the requirements prescribed in ISO/IEC 14651:2007, Clause 6 and its Common Template Table ISO14651_2006_TABLE1 after the application of the EOR delta table specified in Clause 6 of this European Standard. An equivalent description of the resulting tailored table shall equally conform to
42、this European Standard. 5 Tailorability The European Ordering Rules defined in this European Standard can be taken as a default template which can be tailored to the needs of any European country in the manner specified by ISO/IEC 14651 (cf. also informative Annex E). This European Standard is not m
43、eant to influence national standards or traditions in the field of ordering, its scope being the ordering of multilingual data. Nonetheless, national standards are encouraged to express their national ordering rules on this European Standard by declaring a formalized set of deviation rules (”delta”)
44、, as explained in Informative Annex E. This way, the respective ordering rules are automatically machine-processable and can be incorporated into international repositories of locale data, allowing for more widespread support of national ordering standards across software products.
