My Data Science Class Project (see http://federaldata.wik.is/Data_Science) is to re-architect Data.gov so that it responds to the IdeaScale Comments, is reusable, and is interoperable (searchable) with other data catalogs (international and sub-national). I am following an architectural pattern that starts with spreadsheets, uses a wiki for the metadata with well-defined URLs, provides analytics/visualizations, and lays the foundation for ontological engineering. My results so far are at http://epadata.wik.is/EPA_Data.Gov_Inventory.
