Components:

-INPUT DATA - e. g. an image to compress
-It is a SEARCH for the best COMPRESSOR
-a CURRENT BEST COMPRESSED VERSION of the input data [possibly updated when improvements are made]
-a COMPRESSED VERSION of data x is a PIECE OF CODE computing x
-a COMPRESSED LOSSY VERSION of data x is a PIECE OF CODE computing y
     with diff(x, y) small
-SEARCH STRATEGIES
-Compressor SCORERS (mostly by the size of the compressed version)
   (LOSSY compressors are difficult to score)
   
Later:
-SEMANTIC LINKERS that make sense of a compressed version of an image
