Abstract: Techniques for application store topics are described that enable collaboration on application store content between a service provider and third-party collaborators. A framework of topics can be defined to include a plurality of topics to organize application data within pages for interaction with an application catalog. Collaborators can opt to submit content for one or more of the topics that are defined as customizable. The submitted content from collaborators can be incorporated into the topics and/or can replace default content provided for the topic. Different topics within the application store pages can be configured as separate and independent topic containers that can derive content from different sources. In at least some embodiments, content provided for a particular topic container within a page is selected based upon a particular type of device that navigates to the page and/or various device criteria associated with the device.
