ISO/IEC 9541规定了字体资源的体系结构，以及信息处理系统之间字体交换的格式。ISO/IEC 9541还规定了可用于在一般电子文档交换中构造字体引用的体系结构和格式。ISO/IEC 9541-2:20 12规定了字体信息的交换格式，以及交换所需的该信息的最小子集。ISO/IEC 9541-2:20 12需要ISO/IEC 9541-1中定义的特性定义。ISO/IEC 9541-2:20 12定义的字体子集建立了ISO字体资源中必须出现的最小字体属性集。为了适应office和发布环境中广泛的文档和文本处理功能，预计ISO字体资源将包含超过最小数量的字体属性。由ISO/IEC 9541-2:20 12定义的字体资源用于各种文档处理环境中，其中RELAX NG紧凑语法模式(ISO/IEC 19757-2)解析算法被识别。ISO/IEC 9541-2:20 12中定义的字体资源信息的格式以宽松紧凑语法指定，用于一致地生成用于处理环境中的字体资源。

ISO/IEC 9541 specifies the architecture of font resources, as well as the formats for font interchange amongst information processing systems. ISO/IEC 9541 also specifies the architecture and formats that can be used to construct font references in general electronic document interchange.

ISO/IEC 9541-2:2012 specifies the interchange formats for font information, and the minimum subsets of that information required for interchange. ISO/IEC 9541-2:2012 requires the property definitions as defined in ISO/IEC 9541-1.

Font subsets defined by ISO/IEC 9541-2:2012 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 ISO/IEC 9541-2:2012 are used in various document processing environments in which the RELAX NG Compact Syntax schema (ISO/IEC 19757-2) parsing algorithm is recognized. The format of font resource information as defined in ISO/IEC 9541-2:2012 is specified in RELAX NG Compact Syntax for consistent generation of font resources for use in the processing environments.
