Abstract: Methods and apparatus are disclosed for notifying one or more users of information having a plurality of attributes. A plurality of subscribable objects are provided to one or more users, where each subscribable object comprises one or more attributes as required attributes and zero or more of the attributes as optional attributes. Subscription requests are received from one or more of the users based on at least one of the subscribable objects. The subscribable objects are based, for example, on a set of predefined templates. The predefined templates identify each of the plurality of attributes as a required attribute or an optional attribute. Each of the attributes is presented to a user using a display format selected based on a cardinality of the corresponding attribute.

Abstract: Methods and apparatus are provided for subscribing to dynamic attributes. One or more users are notified of information having a plurality of attributes, including at least one dynamic attribute. According to one aspect of the invention, a user can enter a subscription request to be notified when the at least one dynamic attribute changes a value. For example, the subscription request can notify the user when the dynamic attribute (i) changes a value to one or more predefined values; (ii) changes to satisfy a user specified condition; or (iii) changes to a value within a specified range of values. The subscription request can optionally include one or more temporal conditions. For example, the temporal conditions can evaluate whether the dynamic attribute satisfied a value constraint during a given time interval.

For example, the display format for a given attribute may comprise one or more of a user entry, a scrollable list and a check box.
