Abstract: A digital content management system comprises a technology and process, which provides for personalized searching and browsing of digital content in a Digital Content Storefront based upon a real-time contextual merge of cloud-based Digital Content Catalog metadata and individualized, consumer-personalization Contextual Metadata, wherein the Contextual Metadata and Digital Content Catalog metadata are respectively delivered from a set of consumer web services provided at a managed datacenter in combination with a real-time elastic cloud cache, preferably provided by a Content Delivery Network. This system focuses on and expedites end-to-end delivery, caching, and real-time consumer application metadata merging to offer highly scalable and responsive contextual Catalog search and browse results.

Abstract: An installer for a computing device determines firstly whether or not a software package for installation has been signed. If the package is signed it is installed on the device. However, if the package is unsigned, the installer will only install the package on the device if it contains a non-null VID (vendor identity).
