1 Scope
ISO/IEC 24751 is intended to meet the needs of learners with disabilities and anyone who is disabled by their context.
This part of ISO/IEC 24751 provides a common language to describe digital learning resources to facilitate matching of those resources to learners’ accessibility needs and preferences.
Metadata can be used for at least two accessibility-related purposes: to record compliance to an accessibility specification or standard (e.g. for adherence to legislated procurement policies) and to enable the delivery of resources that meet a user's needs and preferences. This part of ISO/IEC 24751 addresses the latter purpose. Metadata to assert compliance to an accessibility specification or standard is not within the scope of this part of ISO/IEC 24751.
This part of ISO/IEC 24751 is intended to be applied in combination with ISO/IEC 24751-2, which provides a means to describe how a user desires to access online learning content and related applications. This part of ISO/IEC 24751 is intended to describe aspects of a computer system (including networked systems) that can be adjusted to improve accessibility. They are not intended to address non-digital systems that can include physical location, other people, external processes, etc.
This part of ISO/IEC 24751 focuses on the description of the characteristics of the resource that affect how it can be perceived, understood or interacted with by users, including
-
a) what sensory modalities are used in the resource,
-
b) ways in which the resource is adaptable, i.e. whether text can be transformed automatically,
-
c) which methods of input the resource accepts, and
-
d) what adaptations are available.
This part of ISO/IEC 24751 provides an information model for describing learning resources so that individual learner preferences and needs (described according to ISO/IEC 24751-2) can be matched with the appropriate user interfaces, tools and learning resources within a computer-mediated learning environment.
