The purpose of this component of the GPII is to both facilitate compatibility and interoperability, and to enable a more rich and diverse set of solutions for a wider range of disabilities and combinations of disabilities. By providing a rich development environment and common components, it is possible to reduce the need for developers to duplicate efforts on the basics and instead focus their activities on the development of more advanced functionality and new features and capabilities.
The Developers Space is split into 4 categories:
The Parts Shelf is a collection and cataloging of software components and services that a developer can use in creating new commercial and free accessibility solutions.
While the parts shelf holds components that are useful in an application, the Tools section contains things that are useful when building your product. For example, an accessibility checker.
The ressources section contains a collection of useful information for AT developers. The information found here is not limited to the implementation part of AT development. Amongst other, it provides providing mainstream designers with the information they need to make their products more accessible from the start - including personas, design patterns, use cases, and other design resources that take into account the needs of people with disabilities. Ressources on currently available solutions, types of needs, etc., can all be found here.
