New in 6.0: Data Handling & Data Sources
Building on the concept of symbolic data description, Mathematica 6.0 introduced the major new "elements" framework for handling import and export of data, in nearly a hundred distinct formats. Mathematica 6.0 also introduced the concept of large-scale integrated data sources, for the first time allowing immediate programmatic use of many forms of real-world data.
Import (modified) — import data, specifying the elements to retrieve
Export (modified) — export data, constructing the output from specified elements
Rasterize — create a bitmap or other elements for graphics
