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 resources defined by this part of ISO/IEC 9541 are used in various document processing environments in which ASN.1 or SGML parsing algorithms are recognised. The format of font resource information as defined in this part of ISO/IEC 9541 is specified in both ASN.1 and SGML for consistent generation of font resources for use in these processing environments.
