Media-Independent Correlation of Information: What? How

Document Type


Publication Date



A wide variety of data in different media (text, structured, image, audio,...) is now accessible in Internet and Intranet. Limitations of current keyword based and hyper-media link based access are all the more apparent when a user wants information without prior knowledge of the locations or media that have data to meet his/her information needs. Two of the several components of the solution being investigated in the InfoQuilt project are discussed here: (a) the use of a wide variety of metadata, that abstract information content without regards to the location, format or media of data and (b) the use of a logical level linking of data called a metadata reference link (MREF) as a hypothetical extension to HTML to support metadata based information correlation between heterogeneous digital media data stored in distributed repositories.
