Hi Thomas, There is already a reasonably good RDF recipe schema: http://donnafales.com/2002/07/28/recipe-schema#
If you want to map hRecipe to RDFa, then the best technique would be to use a combination of the schema above, plus Dublin Core (for authorship) and then create your own vocabulary only to fill in the gaps which the combination of the two more established vocabularies couldn't cover. That would be similar to what Manu has done for his RDFa mapping of hAudio.
For what it's worth, I've already performed a mapping of hRecipe to RDF. (This is basically the way my parser, Cognition, works. All microformats are converted into RDF, and then RDF is converted to, for example, vCard or JSON or whatever. Thus, when I added support for hRecipe, I had to map it to RDF as part of that process.) The mapping I've used is:
hrecipe => http://donnafales.com/2002/07/28/recipe-schema#Recipe recipe-title => http://purl.org/dc/terms/title recipe-summary => http://purl.org/dc/terms/abstract author => http://purl.org/dc/terms/creator published => http://purl.org/dc/terms/issued photo => http://purl.org/media#depiction ingredient => http://donnafales.com/2002/07/28/recipe-schema#ingredient method => http://donnafales.com/2002/07/28/recipe-schema#directions yield => http://donnafales.com/2002/07/28/recipe-schema#x-yield (Namespace squatting a bit here.) preparation-time => http://donnafales.com/2002/07/28/recipe-schema#x-preparation-time (Ditto.) category => http://www.holygoat.co.uk/owl/redwood/0.1/tags/taggedWithTag Within ingredients, I also map: quantity => http://buzzword.org.uk/rdf/measure#quantity item => http://www.w3.org/1999/02/22-rdf-syntax-ns#value note => http://purl.org/dc/terms/abstract optional => http://purl.org/dc/terms/abstract How might all this be used in RDFa? Well, here's an example: <div xmlns:r="http://donnafales.com/2002/07/28/recipe-schema#"; xmlns:dc="http://purl.org/dc/terms/"; xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"; xmlns:m="http://buzzword.org.uk/measure#"; typeof="r:Recipe"> <h1 property="dc:title">Mince and Dumplings</h1> <div property="dc:creator">Toby Inkster</div> <h2>Ingredients</h2> <h3>For the mince</h3> <ul rel="r:ingredient"> <li typeof="r:Ingredient"> <span property="m:quantity">400 g</span> <span property="rdf:value">minced beed</span> </li> <li typeof="r:Ingredient"> <span property="m:quantity">1</span> <span property="rdf:value">carrot</span>, <span property="dc:abstract">chopped</span> </li> <li typeof="r:Ingredient"> <span property="m:quantity">1</span> <span property="rdf:value">onion</span>, <span property="dc:abstract">chopped</span> </li> <li typeof="r:Ingredient"> <span property="m:quantity">60 g</span> <span property="rdf:value">peas</span>, <span property="dc:abstract">shelled (frozen are OK)</span> </li> <li typeof="r:Ingredient"> <span property="m:quantity">500 mL</span> <span property="rdf:value">ale</span> </li> <li typeof="r:Ingredient"> <span property="m:quantity">2 tbsp</span> <span property="rdf:value">tomato puree</span> </li> <li typeof="r:Ingredient"> <span property="rdf:value">worcestershire sauce</span> <span property="dc:abstract">to taste</span> </li> <li typeof="r:Ingredient"> <span property="rdf:value">sage</span> </li> <li typeof="r:Ingredient"> <span property="rdf:value">butter</span> </li> </ul> <h3>For the dumplings</h3> <ul rel="r:ingredient"> <li typeof="r:Ingredient"> <span property="m:quantity">75 g</span> <span property="rdf:value">shredded suet</span> </li> <li typeof="r:Ingredient"> <span property="m:quantity">150 g</span> <span property="rdf:value">self-raising flour</span> </li> </ul> <div property="r:directions"> <ol> <li>Preheat the oven to 190˚C.</li> <li>In a casserole dish, fry the onion gently with a little butter.</li> <li>Brown the beef in the dish.</li> <li>Mix in the other mince ingredients.</li> <li>Bake for 45 minutes, covered.</li> <li>While the mince is baking, prepare a dough from the suet, flour and a little water.</li> <li>Divide the dough into eight balls.</li> <li>After the mince has been baking for 45 minutes, add the dumplings to the dish.
