METHOD AND SYSTEM FOR TRANSCODING WEB PAGES

摘要

Signature schema documents, pre-defined using a query language, provide i nstructions for application by an engine to transcode web pages of respectiv e web sites. Signature schema instructions identify a web page family for a web page and extract a subset of data from the web page in accordance with i ts web page family, each family defined by a shared template. The instructio ns use signatures previously identified for web pages of the same family to distinguish the family from others of the web site and to distinguish the su bset of data from other data for the web page family. A gateway server may p roxy requests from a client machine (e.g. a wireless communication device) a nd use the engine to provide transcoded web page responses. Signature schema instructions may be maintained in a repository coupled to the engine. Extra cted data may be cached to a database coupled to the engine.
