I’m looking for ways of using schema.org with products that have pricing options. There appear to be two main problems 1)      Whilst colour, width, height and depth are all catered for, size appears to be missing – how can we mark up products that are available in sizes that aren’t necessarily covered by width/height/depth (e.g. shoe size). Also, what if the product is available in different finishes – technically, these could not properly be described as colours so how could we mark them up? 2)      There doesn’t seem to be any particularly good way of marking up pricing options that are displayed on the same product detail page. For e.g. if a pricing option table is used like this: | ID | Colour | Price 001-red | Red | £3.99 001-green | Green | £4.49 001-blue | Blue | £4.99 | I can mark up each row as an offer, and give each offer a price and sku or mpn, but then I can’t use itemprop=”color” to describe exactly what the option is. Would I just use itemprop=”name” in this case and abandon color altogether (even though it’s technically supposed to be describing the colour of the product and not the name of the offer)? I suppose another way I could approach it would be to mark up each row as an individual product, and assign each one an offer with the details as described above but then the containing page would effectively look like a separate product – which it isn’t. Any help or advice on this would be very much appreciated
