Abstract: In a networked system connecting a subscriber to a content source via one or more networks, a computer-implemented method includes instantiating a session model for a media session between the subscriber and the content source, the session model to generate session metadata from application-layer interactions between the subscriber and the content source. The method further includes instantiating an interaction model in response to detecting an application-layer interaction in a transport flow of the subscriber, the application-layer interaction comprising media data for the media session. The method also includes generating, at the interaction model, interaction metadata representative of the application-layer interaction, and processing at least one of the interaction metadata and the media data at the session model to generate session metadata responsive to matching the interaction model to the session model.

Abstract: The invention is directed to method of generating database encoded software for controlling operation of a data processing device. The method comprises providing a formal language specification representative of source code for the software, translating said formal language specification into data suitable for storing in database structures and in a form suitable for being queried by a database query language and storing said data in database structures of a database. The method includes using a software development tool in a software development and testing environment to manipulate the database encoded software using a database query language such as SQL and XQuery to develop new software features. The query language can also be used to control replication and/or synchronization of the database encoded software with the contents of a data processing device control program database by way of installing said control program on said device or upgrading the control program software of said device.
