Jeni Tennison has added to her discussion of microdata and RDFa with a new post on how the two might live in harmony. Tennison writes, “One of the options that the TAG put forward when it asked the W3C to put together task force on embedded data in HTML was the co-existence of RDFa and microdata. If that’s what we’re headed for, what might make things easier for consumers and publishers who have to live in that world? In a situation where there are two competing standards, I think that developers — both on the publication and consumption sides — are going to want to hedge their bets. They will want to avoid being tied to one syntax in case it turns out that that syntax isn’t supported by the majority of publishers/consumers in the long term and they have to switch.”

She continues, “Publishers like us at legislation.gov.uk who are aiming to share their data to whoever is interested in it (rather than having a particular consumer in mind) are also likely to want to publish in both microdata and RDFa, rather than force potential consumers to adopt a particular processing model, and will therefore need to mix the syntaxes within their pages. (Of course developers might just avoid embedded data altogether while they wait to see what happens, but let’s assume that they want to press ahead regardless of the lack of consensus from the standardistas.)”
