Abstract: Techniques to manage an electronic program guide may be described. An apparatus may include a display to display an electronic program guide comprising a dynamic scaling grid. The apparatus may also include a media processing device coupled to the display. The media processing device may comprise a processor and an electronic program guide management module for execution by the processor. The electronic program guide management module may manage the dynamic scaling grid on the display. The dynamic scaling grid may comprise content cells hosting program items to display a first set of associated metadata, with the content cells to expand when selected to display a second set of associated metadata for the program items. Other embodiments are described and claimed.

Abstract: Identifying a location of a metadata package to an application program. The system maintains a plurality of metadata packages and locations associated therewith. The plurality of metadata packages is filtered based on attributes in a request received from the application program to identify at least one metadata package. The location associated with the identified metadata package is sent to the application program.

Abstract: Identifying a location and download schedule of web services. Responsive to a request from the application program, the system generates a list of the web services available to an application program along with locations and schedule times associated with the web services. The schedule times implement load management of the web services. The application program accesses the web services at the identified locations at the determined schedule times.

Abstract: An extensible mechanism for storage and interchange of objects is described herein. According to first aspect of the disclosure, objects having respective class definitions are received. The objects are represented in an interchange format by mapping the class definitions of the objects to corresponding fields defined within the interchange format. According to a second aspect of the disclosure, the objects are loaded into a persistent store by mapping the class definitions of the objects to corresponding fields of the store. According to at least a third aspect of the disclosure, a data structure for a unique identifier element is described, along with processes using the unique identifier element to determine whether to update an existing object in the store, or to create a new object in the store.
