The Access For All Specification is intended to meet the needs of learners with disabilities and anyone who is disabled by their context.
This part of the Access For All Specification 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 the Access For All Specification addresses the latter purpose. Metadata to assert compliance to an accessibility specification or standard is not within the scope of this part of the Access For All Specification. |
Purpose
This part of the Access For All Specification is intended to be applied in combination with ‘Access For All Personal Needs and Preferences for Digital Delivery’, which provides a means to describe how a user desires to access online learning content and related applications. This part of the Access For All Specification 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. |
Historic Notes
In July 2003, IMS released IMS Learner Information Package Accessibility for LIP v1.0 and in August 2004 'Access For All Metadata v1.0' . Under agreement, these documents were adopted by ISO/IEC SC36 resulting in the publication, in 2008, of:
- ISO/IEC 24751-1 Access For All Framework and Reference Model;
- ISO/IEC 24751-2 Access For All Digital Resource Description;
- ISO/IEC 24751-3 Access For All Personal Needs and Preferences for Digital Delivery.
The ISO/IEC standard changed the original work to such an extent that there are significant changes in the information model. Also, ISO/IEC did not publish an XSD binding.
As a result, IMS has decided to publish a new set of Access For All documents that are consistent with the ISO/IEC ones (They will be technically identical but combine the IMS and ISO/IEC documentation styles). This document set is Access For All v2.0.
The Access For All v2.0 document set from IMS consists of two documents:
- Access For All Digital Resource Description (which is taken from Access For All Metadata v1.0 ).
- Access For All Personal Needs and Preferences for Digital Delivery (which is taken from IMS Learner Information Package Accessibility for LIP v1.).

Introduction
This part of the Access For All Specification focuses on the description of the characteristics of the resource that affect how it can be perceived, understood or interacted with by users, including:
- What sensory modalities are used in the resource,
- Ways in which the resource is adaptable, i.e. whether text can be transformed automatically,
- Which methods of input the resource accepts, and
- What adaptations are available.
It provides an information model for describing learning resources so that individual learner preferences and needs (described according to the Access For All Personal Needs and Preferences for Digital Delivery) can be matched with the appropriate user interfaces, tools and learning resources within a computer-mediated learning environment. |

ISO/IEC accessibility standars
This document is based upon the original ISO/IEC 24751-3:2008 Information technology — Individualized adaptability and accessibility in e-learning, education and training — Part 3: “Access For All Digital Resource Description”. The ISO/IEC 24751-3:2008 document was a further development of the original IMS GLC Access For All Meta-data Specification, August 2004.
The following referenced documents are indispensable for the application of this specification- ISO 639-2:1998, Codes for the representation of names of languages — Part 2: Alpha-3 code
- ISO/IEC 24751-1:2008, Information technology — Individualized adaptability and accessibility in e-learning, education and training — Part 1: Framework and reference model
- ISO/IEC 24751-2:2008, Information technology — Individualized adaptability and accessibility in e-learning, education and training — Part 2: “Access for all” personal needs and preferences for digital delivery.

IEEE LOM
A profile of IEEE LOM for learning object accessibility meta-data. It contains a description of semantics, vocabulary, and extensions in the format associated with IEEE LOM. There is an encoding of the AccessForAll Meta-data specification, suitable for use with the IEEE LOM, available in documents associated with this one.
|
Dublin Core Metadata Element Set
This is the ISO 15836 standard for core meta-data. There is also the Qualified Dublin Core Metadata Element Set and terms and extensions. Dublin Core meta-data is not domain specific. There is a DC-accessibility Application Profile that provides additional terms for use when describing the accessibility of resources.
|
IMS Content Packaging
This element will be moveable as general content in the content package. IMS best practice requires developers to use the AccessForAll Meta-data with the Content Packaging specification when designing content packages. A description of how this has been done in an early implementation is available in association with this document.
