Abstract: A device may feature a set of containers from different domains, where the containers are restricted from interoperation due to domain restrictions. The device may provide a communication interface that enables simple communication between containers, such as string-based message-passing. While adequate for some uses, it may be difficult to utilize the communication interface in an ad-hoc manner for more complex uses, such as enabling a first container to observe state changes in an object within a second container. Instead, the device may receive a request by an observing container to create an observed container that is associated with a different domain, and to observe a data object within the observed container. Accordingly, the device may monitor the data object on behalf of the observing domain, and upon detecting an update, may transmit a notification of the update to the observing domain through the communication interface between the domain-restricted containers.

Abstract: An asset collection service is provided through a capture of content provided by an external source. A capture management application detects a user selection to create the capture of a portion of the content. The capture is created from the portion by inserting a reference to an asset into the capture, where the asset is located within the portion. The asset is fetched from the external resource using the reference. Additionally, the reference is replaced with the fetched asset within the capture.

Abstract: A browser application may provide one or more bookmarklets, or bookmarklets may be imported to the browser upon user action. Upon first time activation of the bookmarklet, the user may be authenticated and the bookmarklet authorized for that user and the client device. Using a bookmarklet identifier, the bookmarklet functionality may be persisted on the same client device without re-authorization indefinitely, for a predefined period, for a random period, or for a predefined number of uses allowing enhanced protection against malware that may attempt to access user resources through the bookmarklet.

Abstract: Website content curation can be performed through a capture service receiving a clipping of a web page rendered in a web browser. A clipping of at least a portion of the web page can be sent to multiple applications. The source of the clip can remain intact and be provided as part of the clipping. When a region of the web page is selected for a clip to one or more of multiple available applications, the clip can include an extended portion outside of a region specifically selected as the clip. A preview experience can be provided in which the clipping can be viewed and edited.
