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
<http://wiki.gpii.net/index.php/Discussion_on_Profile_Structure_Point34>
topic 34).
*	Jutta: share a preliminary list of needs & preferences for literacy
users.
