An example that makes clear that the difference shouldn’t matter when deciding if and how
availability should be used: You could sell concert tickets, from your online shop and from your retail store, in digital form and in paper form (from both places).
OnlineOnly means that the item can only be purchased from the web shop, while
InStoreOnly is for the opposite case. Both can be used for digital and/or physical items. (I guess they are intended for cases where an organization has both, a web shop and a physical store, but using them in cases where only one is available shouldn’t hurt.)
If you want to convey that it’s a digital item (for download), you could use the
availableDeliveryMethod property with the value
So for a product that can be downloaded after purchase from your web shop, it could look like:
<div vocab="http://schema.org/" typeof="Offer"> <link property="availability" href="http://schema.org/InStock" /> <link property="availability" href="http://schema.org/OnlineOnly" /> <link property="availableDeliveryMethod" href="http://purl.org/goodrelations/v1#DeliveryModeDirectDownload" /> </div>
