17、ble by information communication technology. The World Wide Web technology is one of important technologies among them. This Standard is intended to ensure and improve the information accessibility mainly for older persons, persons with disabilities, and persons with temporary disabilities, when the
18、y utilize these information communication equipment, software, and services, by specifying a set of guidelines for issues which need to be taken into consideration in planning, de- signing, development, production, maintenance, and operation of Web content. “Clause 4 4, General principles” in the te
19、xt defines the general principles that must be considered in all processes of planning, designing, development, production, mainte- nance, and operation in order to ensure and improve the information accessibility. These principles must be understood by all the parties involved such as those placing
20、 orders, developers, producers, operation managers and personnel. “Clause 5 5, Specific requirements for development and production” and “clause 6 6, General requirements for assurance and improvement of information accessibility” de- fine requirements that need to be met in order to comply with the
21、 general principles specified in “clause 4 4, General principles”. Technical requirements which must be taken into consideration in development and production in particular are defined in “clause 5 5, Specific requirements for develop- ment and production”. They are intended primarily for developers
22、 and producers. Specific requirements which must be taken into consideration in (overall) process of from planning to maintenance and operation are defined in “clause 6 6, General re- quirements for assurance and improvement of information accessibility”. They are in- tended primarily for operation
23、managers and operation personnel. This Standard is to be applied also to new technology which is related to the World Wide Web, and expects improvement of more advanced information accessibility tech- nology. 1 Scope 1 Scope This Standard provides a set of guidelines which must be taken into consid-

28、ied to new World Wide Web technology which is in research and development phase. 2 Normative references2 Normative references The following standard contains provisions which, through reference in this Standard, constitute provisions of this Standard.
