Scope

The Accessibility for LIP (ACCLIP) information extends the IMS LIP v1.0 Specification by adding substantial descriptive material that define accessibility preferences. These new elements are intended to be completely compatible with all of the LIP work done previously, especially with regard to privacy, access, and information integrity.
The ACCLIP elements provide a means to describe how a learner desires to access online learning content and related applications via a set of preference elements. These elements are grouped into three main types: display information, control information, and content information. Taken together, they provide a way that allows a learner to create preferences in how content is delivered in a particular context. |
Purpose
The purpose of this specification is to allow information to be gathered from users regarding their needs and preferences so that the user interface and content can be appropriately adapted. These preferences go beyond support for disabled people to include kinds of accessibility needs such as mobile computing, noisy environments, etc.
These preferences will likely have a considerable impact on the user interface of learning delivery, tools, and managers and how content is selected. |

The Accessibility for LIP defines two new sub-schemas for the IMS Learning Information Package that define a means to specify accessibility preferences and learner accommodations.
The <accessForAll> element defines accessibility preferences that were left for future work in the IMS LIP specification version 1.0. The "accessibility" data structure includes the following elements: <language>, <preference>, <eligibility>, and <disability> in the LIP. This specification adds the <accessForAll> element under <accessibility> because it is intended to address the needs of learners beyond those with disabilities. The <disability> element is deprecated henceforth.
In addition to the <accessForAll> element, an extension to the LIP <eligibility> section is included here. The <accommodation> element allows a description of the accommodations made for interactions with a particular learning object (or set of them). Also included is a means to represent who authorized this accommodation, when it was authorized and when it expires. These extensions represent the start of a more systematic approach to describe eligibility and accommodations. |

ACCLIP provides a means to describe how learners prefer to interact with an on-line learning environment. These preferences will likely have a considerable impact on the user interface of learning delivery, tools, and managers and the content delivered by them.
The need to identify and access alternative forms of content for accessibility purposes has been identified. Currently, there are limited provisions for this in the IMS Content Packaging specification. Selection of alternative content forms also has an impact on learning activity sequencing as defined in the IMS Simple Sequencing specification. Accessibility preferences will likely have an impact on how assessments are delivered. These are not currently included in either QTI or this specification. Similarly, Learning Design has the need to identify alternative content, but has no specific provisions for it at this time.

Future Meta-data Work
Besides providing a means to adapt user interfaces to the needs of a particular user, accessibility preferences can also be used to guide the learner in selection of learning material that supports his or her style of learning and accessibility needs. A means is required to enable content to be marked in a manner that supports content search and selection based on accessibility preferences. This will be an extension to IMS Meta-Data but is outside of the scope of this project.
