Data processing

Data have been processed according to a standardized procedure for data documentation mandatory for compilation centers cooperating within the net of excellence EuroFIR. Implementation of the EuroFIR standard for data documentation has been performed at the level of a compiled database reporting a single value for each food/component combination.

Four main entities were documented: FOOD (food description), COMPONENT (component description), VALUE (the main entity for value documentation using EuroFIR Thesauri for matrix, unit, value, acquisition and method type and method indicator) and REFERENCE (citation documentation).

Indexing of foods, which is mandatory according to the EuroFIR standards, has been performed with the LanguaL^TM Thesaurus  using the LanguaL^TM Food Product Indexer
