A taxonomy can be just a list of entries with corresponding translations and other attributes. This is for instance the case for the [[Languages taxonomy|languages]] or [[Countries taxonomy|countries]] taxonomy. Often however it is required to look at a group of entries together based on some kind of communality among the members of the group. This grouping is only done on need basis. We do not need to now languages with  common origin or the countries belonging to South America.

By exploiting the hierarchies defined in the ingredients taxonomy, it is possible to filter on a group of ingredients.

=== Labels taxonomy ===
 
Labels are claims, logos, and other statements found on products. Sometimes these labels are statements which can be checked against the ingredients. For instance the label ''no added sugar'', should imply that the ingredient ''sugar'' is not on the ingredient list. The labels can refer to processes in the value chain, like ''fair-trade'' or ''organic''. These labels can be encoded on the ingredients list as well, but is a bit more obscure.

It is also possible to add storage instructions as labels (lacking better solutions), such as ''frozen'' or ''refrigerated''.

* Or's - the these are labels that have an or in their description (like ''No artificial flavourings or sweeteners''). This should be read as ''No artificial flavourings'' AND ''No artificial sweeteners'' and thus has two corresponding parent categories;
