In order to approach standardization in a systematic way, a common approach is to develop a way to classify the subject area, or a taxonomy. This helps in two ways:
-a taxonomy helps to identify all aspects of the domain in question which might be subject to standardization;
-a taxonomy helps to provide a logical structure for the standardization activity.
A taxonomy has been developed of relevant concepts in the domain of European localization requirements, based on user requirements for functionality, as discussed in Clause 4 of Part I of the CEN/TC304/PT01 report on User requirements on IT.
By way of an application, all known current standards and standardization
activities have been grouped according to this taxonomy, thus forming another
type of taxonomy, that of the standards themselves.
The present classification of the concepts was made through the identification of commonalties, such as characters, sets, fonts and rules relating to presentation. The analysis was based on a much wider view of "multi-cultural support", which attempts to map some of its concepts. Areas relevant to this taxonomy were chosen and developed into the full taxonomy, shown in clause 3.2. This latter choice comprises the technology which relates to methods for specifying, and rules governing, the creation of unique properties and codes which facilitate the presentation, storage and transmission of individual characters.
The taxonomy in clause 3.2 was based on references ISO/IEC TR 10000-1, ISO
TR 12382 and IEC 824 and the activities of appropriate standardization bodies,
but most notably the work of CEN/TC304 and ISO/IEC JTC 1.
User requirements may be summed up in the single phrase "multi-cultural support", being the need to accommodate all the requirements of different types of users, whether they are racial, national, typographical, occupational or individual. The primary choice was for text based topics, in line with the capability of computer technology to code, store and process individual characters.
The taxonomy in clause 3.2 takes the classic form of a tree structure, where two major classes are recognized; Locales and Characters. The former deals with the cultural environment of the user, the latter with the smallest divisible parts that make up the messages which are being electronically processed.
A taxonomy of whatever phenomena can be constructed in several ways, depending on its purpose and the aspects applied. (For instance, a number of persons may be grouped firstly according to age, then according to gender, then according to place of living -- or precisely the other way around, according to need.) A taxonomy for standardization purposes naturally has to take into account the most practical ways to group existing standards and standardization projects as well as the logical connections between them and any conceptual "holes" which may need to be filled in order to cover the full need for standardization.
The following taxonomy is thus intended to provide a map for almost all of the user requirements. Therefore the level of subordination in some cases go very deep -- this does not mean that the actual standardization projects need a taxonomy of the same complexity. When a sub-level is empty of existing or future standards, the entries in that sub-level are simply collapsed and only the level above remains.
What follows is a specification of the taxonomy, and for informatioon, an
application of this to standardization and research projects currently going
on. The purpose is to illustrate one use of the taxonomy as well as to provide
a map of where the respective work is being carried out. To the taxonomy there
is an additional layer of where the specifications apply, such as world-wide,
Europe or a specific country.

To allow widespread use of, and comment on, this taxonomy it is proposed
that it should be published as a CEN/TC304 standing document and given adequate
publicity as a freely accesible page on the CEN/TC304 web pages. It is
recommended that the upkeep, development and maintenance of the taxonomy should
be the responsibility of CEN/TC304.
