Abstract: Methods, computer readable mediums and systems provide media player users with a full contextual metadata experience. Metadata include multiple forms of property data, or information, relating to media accessed by a media player, such as a CD in a CD-ROM drive of a computer. Metadata is transferred from a server to a client. Identification parameters associated with the accessed media file are submitted by the client to a server, and property data is retrieved and forwarded to the client. The metadata provides the user with integrated, contemporaneous property data directly related to the media file being played, providing automatic, integrated access to data from multiple databases, simply by accessing a related media file through a media player, without further direction from the user.

Abstract: Systems and methods are described for declarative client input security screening. A configuration module in a web-based application (or project) that includes one or more web pages is designed to allow client input to be screened for the web pages by declaring particular screening attributes and actions therein. A global section in such a configuration module includes security screens that apply to input of all types, while other individual sections include security screens that apply only to input of particular type. The global section provides a way to consolidate screening that applies to all client input types, thereby precluding redundant screens having to be maintained in each individual section. Client input that survives the security screening is cached and used in normal page processing. By including the security screens in a declarative section, maintenance is made more efficient and reliable.

Abstract: Individual records of a data set include data and semantic information to describe the data. The records in the data set are encoded to generate an encoded data set using a compression function which is determined from semantic information that is common to multiple records of the data set. Multiple records of the encoded data set include the data without the common semantic information. The encoded data set is transmitted, or otherwise communicated, to a destination device along with an expansion function that includes the semantic information that is common to the multiple records of the data set. The destination device expands the encoded data set with the expansion function such that the multiple records of the encoded data set are expanded to include the common semantic information.
