Dear Liddy,

Thanks for sharing this draft. I have a few questions and comments:

(1) In the telecons so far, people involved in the Cloud4All project have focused mostly on (UI) adaptation, and this has driven many proposals and decisions. But the revised ISO/IEC 24751 should also cover the matching between user needs/preferences and resources (i.e. resources that don't necessarily adapt themselves). Do you think that the latter goal is insufficiently covered by the proposals and decisions so far, or that some of these are suboptimal (or worse) for this objective?

(2) The first sentence reads: "ISO/IEC 24751 is intended to facilitate the matching of individual user needs and preferences with digital resources that meet those needs and preferences." I would appreciate it if the concept of adaptation/adaptability could be included in this sentence. (When reading the draft for the first time, the current wording gave me the impression that adaptability was downplayed compared to providing matching resources; I had to reread it to see that this was not the case and that the first sentenced had "primed" my mind in that direction.)

(3) In the proposed structure, parts 2 and 3 are about the registry/registries. Where will topics such as conditions and matching (including conflicts) be covered?

(4) Should the definition of "matchmaker service" also take into account that context parameters such as location, ambient light and ambient noise (in addition to time) may also be taken into account?

Best regards,

>> Personal Needs and Preferences (PNP) Profile
>> A PNP profile is a flat list of user Preferences. A Preference consists of a ...
>>     • Property, which serves as a link to the registry to obtain the definition of the Property. For example "FontSize".
>>     • Value, which states the value the user wants for the given Property. The Value conforms to the Property definition.
>>     • "Über-Condition", which specifies in which circumstances the Value should apply.
>> Inferred Preferences
>> The user profile contains ONLY preferences set or verified by the user. Preferences which were inferred by a MatchMaker are not stored in the user profile, as they are MatchMaker specific and using multiple MatchMakers at once would cause problems. If a user verifies and confirms an inferred preference through any means, it may be added to the user profile.
>> History
>> A preference server may support keeping track of old values in a PNP profile. This might be useful for some matchmaking tools.
>> "Über-Condition"
>> "Über-Condition" is expressed as a Boolean expression. If it evaluates to "true", the preference applies. If it evaluates to "false", or if there is insufficient information available to evaluate the condition, or if an error occurs, the preference does not apply.
>> Preferences can occur in different formats in a system (e.g. in a preference server, on a client, etc.). Conditions are a way of expressing a set of preferences each for a different situation. A "resolved profile" with "resolved preferences" does not contain conditions, because it has been applied to a specific situation (i.e. the conditions are resolved based on the situation). A "partially resolved" profile has some conditions resolved, but not all.
>> Conflicts
>> There might be situations where the conditions of multiple preferences with the same property evaluate to true. In this case, the order of the preferences in the profile is significant. The first/last?? preference wins. Note that the order of preferences is independent from their date/time of creation.
>> Action Items
>>     • Look at existing ISO standards that use a registry approach. (See topic 43.)
>>     • Formulate proposals for dealing with conditions (see topic 34).
>>     • Jutta: share a preliminary list of needs & preferences for literacy users.
