Is it legal to publish photos of products and their packaging? Can such be done anonymously on some open license? (which would be the best for such data to be open for public use, as products are generally available to see in shops for everyone?)
Where and how to publish?
Is Wikidata+Wikimedia right place?
I am thinking on (structured) data, that includes:
- packaging photo
- product photo
- derived information
- barcode(s) (EAN)
- weight, nutrition, etc.
What information requires publishers to be careful regarding sharing (e.g. prices in given shops)?
Thanks to insight from one of the answers the topic of "copyrighted materials" or "trademarks" on packages was pointed out. Fair concern. Therefore, let me frame question in direction of purpose, so additional questions, requirements:
- what additional steps would make such collection feasible? (something that scales and is feasible for crowdsource preferably, e.g. "blurring out"/"black out" parts of images with products logos ? Converting to "black&white"? (unless product owner comes and gives permission by him/her self)?)
- goal is to collect most "data" about product: barcode, ingredients, dietary information, amount of contents (ml,pieces,grams), plus eventually approvals from organizations.
- imagine use case: you want to find set of products that compose into desired meal, but need to take care of allergies, diabetics and other constraints. Such db when cross across shops in (or webshop delivering to) your area, could provide valuable suggestions!
