EuroFIR THESAURI

Use of special standardised controlled vocabularies (thesauri) for food composition data (FCD) description is one of the key elements of harmonised and standardised EuroFIR specifications for FCD processing. The specifications are based on a relational database model containing four main and other additional entities. The four main entities (Food, Component, Value, Reference) are mandatory for data documentation and they build the core set that is necessary for proper description of FCD (for more details see the references below). 

The description of the food is regulated through the LanguaLTM Thesaurus. Its web page provides access to current and archival versions of the thesaurus, information about updating and other topics, and access to the Food Product Indexer tool to help describing the foods.

The following table presents eight EuroFIR Thesauri that are used for documenting the value of a component in a given food. The list also includes the EuroFIR Food Classification thesaurus used for harmonized classification of foods in food composition databases. Brief description of each thesaurus, version number and publishing date of its current version and use of thesauri for data documentation within mandatory entities is presented.

Access to the thesauri

An access to EuroFIR thesauri (current and archive versions) is possible using the EuroFIR eThesaurus Manager tool http://ethesaurus.eurofir.org/Default.asp  (username:  eThesaurusGuest, password: guest$Welcome).

The eThesaurus Manager tool is primarily a curator tool for maintenance of and update of the EuroFIR Thesauri, but it also enables a read-only viewing of individual records of thesauri terms and access to the export reports in the following formats:

   
Systematic display (tree view) tab delimited file listing the thesaurus’ descriptors systematically according to their place in the thesaurus hierarchy.
Alpha-numerical display tab-delimited text file listing the thesaurus according to the alphanumerical descriptor code. The first line in the tab-delimited file is the root of the thesaurus and indicates the thesaurus name and version.
Alphabetical display thesaurus descriptors and synonyms listed in alphabetical order for printed documentation.
XML-format display designed for use in IT applications

For more details about the eThesaurus tool see its description.
