Jan 13, 2013 · RDFa is an attempt to get both the flexibility of RDF and the simplicity of microformats. Microdata was a response to RDFa, but with a different data model (roughly arrays and hashes rather than a relational model). Unlike microformats neither dictate what sort of information is provided, just how it is encoded.

Mar 21, 2019 · The specifications RDFa Core and HTML+RDFa may be more complex than HTML Microdata, but it’s not a "fair" comparison because they offer more features. Similar to Microdata would be RDFa Lite (which "does work for most day-to-day needs"), and this spec, at least in my opinion, is way less complex than Microdata.

Jul 17, 2015 · The vocab attribute is defined in RDFa 1.1, but with your current DOCTYPE, you are using RDFa 1.0. Your options: Keep using XHTML 1.1 and RDFa 1.0, and use the xmlns:… attribute(s) instead of the invalid vocab attribute:

Mar 12, 2014 · The property attribute comes from RDFa. RDFa 1.1 extends HTML5 so that it’s valid to use meta and link elements in the body, as long as they contain a property attribute.

Jan 13, 2014 · Essentially when your viewpoint is the markup itself, as it would be for CSS, they would be siblings. Your RDFa is basically saying, these li's correspond to some underlying data structure. So regarding a semantic viewpoint that wants to figure out what they represent, your RDFa explains they are actually hierarchical. –

Jun 10, 2011 · One way is to use an RDFa parser to extract the triples from the RDFa document, and then process them in your app. this is what Google and co do in their search engines, I imagine. Alternatively you can tell a SPARQL store (either in memory or persistent) to load the document, either with it's API, or SPARQL 1.1's LOAD command, and then use ...

Sep 28, 2015 · Just parse the RDFa, convert to formats of your preference, and embed (in script) or link (with rel-alternate) it if it makes sense. But yes, adding RDFa is often more complex than adding a JSON-LD blob, because you have to adapt it to the existing markup. (However, it should not "break validation" unless you’re making mistakes.)

Jun 1, 2013 · To summarize the best practices from RDFa Lite 1.1 you can also check out the RDFa 1.1 Primer: stick to @vocab, @prefix, @property, @resource, and @typeof; avoid making more than one statement in a given element
