I've implemented a website with odoo14 community edition. After checking performance on Google Search Console, I found that i was getting warning messages that the following details are missing.
Either "offers", "review", or "aggregateRating" should be specified
Missing field "brand" (optional)
Missing field "description" (optional)
Missing field "sku" (optional)
Missing field "image" (optional)
No global identifier provided (e.g., gtin, mpn, isbn) (optional)
Only types - url and name are working correctly.
However, in the odoo 14 documentation, mentions that it implements microdata as specified in Schema.org. But i don't see that its working.

The same thing happens in v13. For things like SKU, I can sort of understand it since Odoo doesn't have a way to simply show the Internal Reference on the product page. Similar for barcode, etc.
The one that baffles me the most is "description". Odoo shows that so I have no idea why that one wouldn't be shown.
I really hope they work to improve this as this is one area where Shopify, our old platform, really knocked it out of the park.
