The use of open networks for the interchange of documents in both office and publishing environments has shown the need for a mechanism enabling the interchange of font information.
It is forseen that publishing and office technologies will merge and that this development will be facilitated by definition of a standard font resource architecture and a limited number of standard font resource interchange formats,
The first edition of ISO/IEC 9541-2 was published on 1991-09-15. After the publication, the following amendmentds and corrigenda were published.
This second edition of ISO/IEC 9541-2 includes all the amendmentds and corrigenda, and other requirements provided in the discussions in ISO/IEC JTC1/SC34.
ISO/IEC 9541, as a whole, specifies the architecture of font resources, as well as the formats for font interchange amongst information processing systems. It also specifies the architecture and formats that can be used to construct font references in general electronic document interchange.
This part of ISO/IEC 9541 specifies the interchange formats for font information, and the minimum subsets of that information required for interchange. This part of ISO/IEC 9541 requires the property definitions as defined in ISO/IEC 9541-1.
Font subsets defined by this part of ISO/IEC 9541 establish the minimum set of font properties that must occur within an ISO font resource. To accommodate the broad range of document and text processing functions found in office and publishing environments, it is anticipated that ISO font resources will contain more than the minimum number of font properties.
Font resource defined by this part of ISO/IEC 9541 are used in various document processing environments in which RELAX NG parsing algorithms is recognised. The format of font resource information as defined in this part of ISO/IEC 9541 is specified in ISO/IEC19757-2 for consistent generation of font resources for use in the processing environments.
