Products' synonyms (correlates with import of offers)

[twothreenine]

Products should have something like a list attribute with synonyms (how they are also called, in other languages etc.)
For example: spelt grains = spelt whole, spelt, Dinkel, Dinkel Körner, Dinkel ganz
This is important for import scripts to correctly relate products on a price list from a supplier to existing products.
My plan is to make a new class for Synonyms with the following attributes:
language = ManyToManyField
comment = TextField

These lists should be editable easily in the program.
