This is a multi-part message in MIME format. --------------D67B112E00A4DA9E64D31F76 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 8bit Hi all, When we publish image documents with ImageSnippets, we serialize in both JSON-LD and RDFa..we have the data right there, so it was easy to do both simultaneously. We started with RDFa, but when I noted that more people were migrating to JSON-LD, we just added the JSON-LD to our documents. When I need to read the source of the html page as a human, I find the RDFa easier to follow, so I think I left it for humans as much as anything else, but thought - what the heck, use them both, t won't hurt.
