3. System Description and Behavior Examples

We will use an informal approach to modeling behavior in this specification. Due to the relationship of this specification to the Learner Information Package Accessibility for LIP (ACCLIP) specification and the boundaries created in the charter we will limit the scope of the behavioral descriptions.

Correctly implementing the combination of AccessForAll information (from the ACCLIP Specification) and accessibility meta-data from this specification requires handling a set of standard cases in a well-defined way. Our goal is to provide functional interoperability that will support the substitution or augmentation of one resource with another when this is required for accessibility purposes, as prescribed in the user's profile (e.g., the addition of caption text for a hearing-impaired context), thus allowing interoperating systems to work together to serve the needs of learners with disabilities and others who have AccessForAll profiles. This section provides a flowchart that lays out a general strategy for using these two sets of data together, and then provides three specific examples of element values that should cause implementations to behave in specific ways. These examples present a simple form of pseudo code, indicating the specific elements relevant, and the values to test for.

3.1 Behavior Workflow

The following workflow diagram describes an overview of Accessibility behaviors:

A diagram illustrating accessibility behaviors

Figure 3.1 Flowchart of behaviors for interoperability using ACCLIP and ACCMD.

Text description of Figure 3.1: A diagram displaying the behaviors for interoperability using ACCLIP and ACCMD. The diagram is a flow chart displaying the start and end states for systems analyzing a learner's ACCLIP against a primary resource's ACCMD. The steps outlined in the diagram are as follows:

1. The system asks, "Does the primary resource contain a modality in which the learner requires alternatives to?"

1.1. If no, the system displays the primary resource.

1.2. If yes, the system retrieves the list of equivalent resources described in the ACCMD.

1.2.1. The system loops asking on each iteration, "Are there more equivalent resources in the list?"

1.2.1.1. If yes, the system gets the next equivalent and asks, "Does this equivalent resource contain the necessary alternatives in order to meet the user's ACCLIP preferences?"

1.2.1.1.1. If no, the system goes back to 1.2.1.

1.2.1.1.2. If yes, the system asks, "Is the equivalent resource an alternative resource (as opposed to a supplement resource)?"

1.2.1.1.2.1. If yes, it displays the equivalent resource.

1.2.1.1.2.2. If no, the resource must be a supplement resource and is combined with the primary resource and displayed to the user.

1.2.1.2. If no, the system searches the repository for additional resources claiming to be equivalent to the primary resource.

1.2.1.2.1. If any are found, the system loops and follows the behavior in 1.2.1.

1.2.1.2.2. If none are found, the user is warned that the content does not meet his/her content preferences and the original primary resource is displayed.

3.2.2 Displaying Audio Description

Note: This part of the model does not answer the issue of what if more than one kind of description is available. One could check ACCLIP usage parameters to see which is most preferred, and the implementer must decide how to distinguish between videos and stills.


Step	Element to examine	Test
if primary has visual	resourceDescription.primary.hasVisual	true
