[Accessforall] Draft of new standard

Let me rephrase my second question.  One of the statements in the current conformance section is: "IT systems are conformant when they gather and/or process Personal Needs and Preference descriptions as specified in ISO/IEC 24751 to deliver digital resources that match each user's needs and preferences.". I know we don't support the description of persons in this standard (or in Cloud4all), but that was not my question.
The issue is as follows: Assume that a system stores both needs & preferences AND characteristics of users. Since it stores needs & prefs, it meets this conformance requirement. I think the current wording in the conformance section does not *prohibit* the storage or processing of use characteristics. Is this intentional? (Or am I just paranoid? ;-) )

>> (1) The scope section states: "ISO/IEC 24751 is intended to facilitate the matching of resources to user's individual requirements by providing common terms for describing those requirements so they can be matched to resources that satisfy the requirements." But what about groups of users? The approach taken by the VUMS cluster does not assume that a user profile can only belong to an individual user: "A user profile is an instantiation of a user model representing either a specific real user or a representative of a group of real users" (from the VUMS Cluster white paper: <http://www.veritas-project.eu/vums/wp-content/uploads/2010/07/White-Paper.pdf>).
>It is, I believe, made clear that a profile might be only one of many that a single user, in fact, uses throughout their time. Similarly, it is expected that a number of users with similar needs will, at times, all use a single profile. I will try to make sure this is made clear. One of the problems, of course, is that a set of users may have conflicting needs but that is not your question, I realise.
>> (2) The registry is supposed to contain terms that enable the description of needs and preferences, as opposed to medical or functional characteristics of users. However, will Part 1 and/or the conformance clause state that terms for medical or functional characteristics make the implementation non-conforming? The current draft does not prohibit terms for medical or functional characteristics.
>Our work has very deliberately not supported any description of people - their needs are not considered definitive of them, etc., and we don't support descriptions such as: resources for a blind person. This approach is based on the belief that as people are so different in their skills and needs, it actually does not make sense to do this anyway.
