摘要： A technique for content management using group rights is described. The technique facilitates a flexible management for a group of content files mainly by effecting a change of group memberships for subsets of the group and a partial update of the content files. As one aspect, a content file manager (20) is provided to create content files associated with group rights. A device (21) is also provided to process such content files. One method aspect comprises assigning a plurality of content items to a new group whose identifier is associated with a new group rights object; determining if any of the content items has been previously distributed; and for each previously-distributed content item, creating an update content file including the group identifier of the new group and excluding the previously-distributed content item itself.

摘要： A technique for creating a resource in a cloud computing system is described. A method implementation of this technique comprises providing a plurality of predefined base resource descriptions, each base resource description defining a base resource in the cloud computing system and specifying one or more properties of the base resource, providing a plurality of predefined modifiers, each modifier being applicable to a resource in the cloud computing system to add, remove or change a property of the resource, wherein each modifier is associated with metrics information, and receiving a resource request indicating one or more desired properties for a target resource in the cloud computing system. In response to receipt of the resource request, a selection operation is performed to select a base resource description and one or more modifiers that are to be applied to the base resource corresponding to the selected base resource description to create the target resource in the cloud computing system, wherein the selection operation is based on the metrics information. In a next step, the selected base resource description is deployed to create the corresponding base resource in the cloud computing system, and application of the selected modifiers to the base resource in the cloud computing system is triggered to create the target resource.
