Hi Jason,

HTML+RDFa is great in a sense that you have a single document which is 
useful for humans as well as machines. While publishing (read purposes) 
only in RDFa is okay, you might want to consider the remaining CRUD 
operations, if you have to deal with it from the outside.

You are welcome and encouraged to take what you like from here:


To summarize: the RDFa templates are written as HTML5 Polyglot documents 
(fancy way of saying that it can act as HTML5 or XHTML5 given respective 
content-type in the response). See the examples, click around the menu 
(e.g., LNCS, ACM). Dereference the URLs for RDF. Use a Line Mode Browser 
e.g., links, and see in fact that all of the content is there. It is 
"religiously" progressively enhanced. There are ways to embed Turtle and 
JSON-LD into these documents, and you can export etc. More work on the 
authoring end is on its way.

Feel free to ping me off the list for any details and future goals.
