Abstract: A method and system are described for tracking user activity related to network resources using a browser. According to an exemplary embodiment, a user-initiated activity related to a network resource is detected in the browser. The detected user-initiated activity is associated with the network resource to form an activity-resource pair. The activity-resource pair is associated with a record in a data store related to the detected activity or the network resource. By associating the activity-resource pair with records in the data store that relate to the network resource and/or the detected activity, the information in the data store can be used to add context to and provide insight into users' browsing activities.

Abstract: A communication protocol for distributing information related to a resource in substantially real-time to a subscriber includes a first HTTP request message for allowing the subscriber to request a subscription to the information related to the resource, where the first HTTP request message includes subscription data in a header and/or in a Uniform Resource Identifier (URI) reference associated with the first HTTP request message, and the subscription data identifies the first HTTP request message as a subscription request. The communication protocol also includes a second HTTP request message for allowing a publisher to update the information related to the resource, and an HTTP response message for allowing a publish/subscribe service to notify the subscriber of the updated information related to the resource each time the publish/subscribe service receives the second HTTP request message from the publisher.

The detection of the activity change includes a second device communicating the activity change with a presence service. The method and system also include automatically altering the capability of the device if the change in the status is detected or automatically altering the status if the change in the activity is detected.

Abstract: A communication protocol for distributing information related to a resource in substantially real-time to a subscriber includes a first HTTP request message for allowing the subscriber to request a subscription to the information related to the resource, where the first HTTP request message includes subscription data in a header and/or in a Uniform Resource Identifier (URI) reference associated with the first HTTP request message, and the subscription data identifies the first HTTP request message as a subscription request. The communication protocol also includes a second HTTP request message for allowing a publisher to update the information related to the resource, and an HTTP response message for allowing a publish/subscribe service to notify the subscriber of the updated information related to the resource each time the publish/subscribe service receives the second HTTP request message from the publisher.

Abstract: A method and system for enabling a user to specify and automate file handling in a portable image capture device is provided, wherein the device includes at least one stored file and is capable of communicating with a computer over a network. An action list is downloaded from the computer to the device, wherein the action list includes a mapping of one or more user input events on the device to one or more file handling actions. When an input event on the device is detected that matches one of the events in the downloaded action list, the corresponding file handling action is then performed on the file within the device. In a preferred embodiment, prior to the action list being downloaded, the user is allowed to configure the action list on the computer by mapping one or more user input events on the device to one or more file handling actions.
