Towards a Recipe microformat. Please read the process before editing this page.


For the sake of clarity the format-in-progress from september 2007 was moved to recipe-brainstorming-archive. ThomasLoertsch 14:12, 11. Nov 2008 (CET)


format-in-progress - #2 - october 2008

Introduction

Recipe is based on examples and fields in existing formats. The recipe microformat is designed for the mark-up of instructions for creating meals, drinks or food-based items.

Please note that Format-In-Progress sections are intended to be edited to reflect the discussion that occurs on the microformats-new list, rather than being a free-form playground for schema. This Format-In-Progress was produced by ThomasLoertsch 15:29, 15. Oct 2008 (CET)

Changelog

This second Format-In-Progress reflects the discussions following the first one from september 2007 (see recipe-brainstorming-archive). It is not an entirely new format-in-progress proposal but rather an evolution from the september07-version and about 90% the same. A short overview of changes:

Root Class Name

To be decided. Likely ‘hRecipe’.

Property List

Class names author, photo and note are taken from hCard, published used from hAtom and item from measure.

Field Details

Title: The title of the recipe.

Summary: The summary provides a short introduction or an accompanying statement about the recipe.

Author: Author the person who authored the recipe.

Date published: The date the recipe was published.

Photo: Accompanying image.

Ingredients: Describes the ingredients used in the recipe.

Ingredient: Describes one ingredient used in the recipe.

Note: A note concerning an Ingredient or a Preparation Time element (for element Preparation Time see below).

Method: The method of the recipe.

Yield: Specifies the quantity produced by the recipe.

Preparation Time: The time it takes to prepare the meal described by the recipe.

Nutrition:

brainstorming

RecipeML-based Brainstorm

NOTE: Brainstorms should be based on implied schema of examples, not on explicit schema of other formats. The only exceptions where this appears to have been ok (perhaps I got lucky) was with hCard (based on vCard) and hCalendar (based on iCalendar), but even in those cases, experience has shown that there are several properties in each that in practice have not shown much if any use, therefore indicating that the microformats were/are bigger than they need(ed) to be. Tantek 23:19, 27 December 2008 (UTC)

Excerpted from Conor Bandon's Blog entry and derived from The RecipeML Spec:

Cookcamp brainstorming

At CookCamp in February 2007, Tantek moderated a fairly free form discussion of how to publish/share recipes. Here is a photo of the whiteboard: 422072573_9956d93f61.jpg

To Do: OCR this and enter rough notes here...

Additional Suggestions

<ul class="ingredients"> <li>Booze <ul> <li>1 part <span class="name">Rum</span></li> </ul> </li> <li>Mixer <li>1 part <span class="name">Cola</span></li> <li>1 part <span class="name">Lime juice</span></li> </li> </ul> --Yde 13:09, 18 Apr 2008 (PDT)

<p class="method">Take <span class="ingredient"><span class="quantity">a handful</span>

of spinach</span> and fry it</p> --BenWard 13:20, 18 Apr 2008 (PDT) 
I like to eat <span class="hRecipe"><span class="ingredient">cheese</span></span> for supper.

or simply (if the proposed "sub-microformat-pattern" is adopted): 

I like to eat <span class="hRecipe-ingredient">cheese</span> for supper.

Quantity

There are a lot of units typically used in recipes that do not make much sense in most other cases and therefor most likely will never make it into a 80/20-aware measure-microformat. This is a deliberatly short list:

note can be used to indicate more subtle differentiation (like a "big spoonful", "some leaves" etc). I think this list is both usefully short and complete. The following measures:

can be taken from the measure microformat. I guess measure is already stable enough that it's save to use these terms "experimentally". The measure-element should be optional. That way nobody is forced to select a value from it - it's just a help to facilitate interoperability. --ThomasLoertsch 15:45, 01 Oct 2008 (CET)

Proposed Optimisations

Item

Can we have this optimisation?... if no "item" is found, the entire ingredient is taken to be the item. TobyInk

Example: 

<span class="ingredient">salt</span>

is a shorthand for: 

<span class="ingredient"><span class="item">salt</span></span>

Ingredient List

TobyInk 03:42, 23 Mar 2008 (PDT):

If class="ingredients" (note: plural) is found on an element, class="ingredient" (note: singular) is automatically implied on all its children. 

<ul class="ingredients">
<li><span class="quantity">3</span> <span class="item">eggs</span></li>
<li><span class="quantity">6 oz</span> <span class="item">self-raising flour</span></li>
<li><span class="quantity">6 oz</span> <span class="item">caster sugar</span></li>
<li><span class="quantity">6 oz</span> <span class="item">butter</span></li>
<li><span class="quantity">1 tsp</span> <span class="item">vanilla essence</span></li>
</ul>

is a shorthand for: 

<ul class="ingredients">
<li class="ingredient"><span class="quantity">3</span> <span class="item">eggs</span></li>
<li class="ingredient"><span class="quantity">6 oz</span> <span class="item">self-raising flour</span></li>
<li class="ingredient"><span class="quantity">6 oz</span> <span class="item">caster sugar</span></li>
<li class="ingredient"><span class="quantity">6 oz</span> <span class="item">butter</span></li>
<li class="ingredient"><span class="quantity">1 tsp</span> <span class="item">vanilla essence</span></li>
</ul>
