Multi-language attributes in MongoDB
Wholesale recommendations over your schema design may be a bit broad a topic for discussion here. I can however suggest that you consider putting the elements you are showing into an Array of sub-documents, rather than the singular sub-document with fields for each item.
{ sku: "1011", name: [{ "en": "cheese" }, {"de": "Käse"}, {"es": "queso"}, etc... ], price: [{ "usd": 30.95 }, { "eur": 20 }, { "aud": 40 }, etc... ]} The main reason for this is consideration for access paths to your elements which should make things easier to query. This I went through in some detail here which may be worth your reading.
It could also be a possibility to expand on this for something like your name field:
name: [ { "lang": "en", "value": "cheese" }, { "lang": "de", "value: "Käse" }, { "lang": "es", "value": "queso" }, etc... ]All would depend on your indexing and access requirements. It all really depends on what exactly your application needs, and the beauty of MongoDB is that it allows you to structure your documents to your needs.
P.S As to anything where you are storing Money values, I suggest you do some reading and start maybe with this post here:
