Types of MH370 Data

Raw data:  Raw data is the information that an experimenter or observer collects and/or receives from her equipment or others.

“Raw” means that it has not been processed by the collector/receiver for use or permanent storage.

Basic data:  Basic data is data input to either end of a protocol stack.  In terms of the Open System Interconnection (OSI) Technical Reference Model (TRM) it is the input to the Physical Layer and/or the Application Layer.  People frequently associate basic data with only the input to the Physical Layer.

Data and metadata:  Data is a set of symbols.  Metadata describes how to interpret the symbols.  In a 3-level hierarchy such as data, information, and meaning, metadata describes how the information is represented (captured?) in the data.

The MH370 "basic data" is available at http://bit.ly/1h7s4xw.

Miles' Law seems to apply to all these.  A description of Miles Law is available at http://www.leadershipnow.com/leadingblog/2008/02/miles_law_and_six_other_maxims.html
