Resources that are made available electronically are often not in a suitable form for users because the users have particular needs resulting from their choice of devices, user agents, circumstances or perhaps a disability. While many of these problems can be adjusted automatically, there are some that can't and, as much as anything, should not be adjusted without input from the user about how they want these adjustments made.You can read about the AccessForAll accessibility strategy on the DC Wiki.
Currently, there is no way for a user to determine if a resource will satisfy their needs, or to allow a system to automatically match a user's specified needs to the characteristics of a resource, in a way that enables all users to access content equally. Metadata descriptions of resources (and a user's needs) can be used to provide the necessary information and the term being proposed aims to facilitate this.
When a resource does not itself have the necessary accessibility characteristics or components, they may nevertheless be available and discovered as the result of a suitable search, in which case they could be assembled into the original resource for the user.
