<p>The following are real-world examples and brainstorming for marking up currency.</p>
The following are real-world [[examples]] of pages that have amounts of money that could be marked up with a '''[[currency]]''' microformat. As part of the microformats process:
* [[currency-examples]]
* [[currency-formats]]
* [[currency-brainstorming]]


== The Problem ==
== Real-World Examples ==
<p>Currency is a reasonably easy problem to solve as indicated by the [[#Existing_Practices]].</p>
''Links to public web pages, either popular or insightful''
 
===Google Financials===
Use of currency amounts in tables.


<p>"Amounts" in arbitrary units is a bit harder and necessary for several applications.</p>
Representing currency amounts in a table format is very common. For instance, see [http://investor.google.com/fin_data.html Google Financials].


<p>For example, consider the work that has been done on a recipe microformat.</p>
In this table representation, it does not make sense to provide the currency information for each cell. Instead, it should be provided once at the table, thead, tr, or th, level, and then a td may override the default value. This is very similar to the common practice of indicating the currency and formatting in plain english: "Numbers in thousands of dollars" in the table title/subtitle or legend.


[[recipe-examples]]
The microformat for currency amounts should provide a way to represent a default currency for all children of a table, thead, tr, or th nodes.
The currency symbol/abbreviation should be optional in for elements defined as containing currency values/amounts, if a default currency has been defined in one of the ancestor elements.


<p>Though we haven't reached this problem yet in the research, I can see it
=== UK Government Data Standards Catalogue ===
coming:</p>


<p>Say you wanted to create a "shopping list" application which you could tell which recipes you wanted to cook, and have it automatically total up all the various amounts of ingredients and give you the net amount of stuff you wanted to pick up.</p>
[http://www.govtalk.gov.uk/gdsc/html/frames/AmountSterling-1-0-Release.htm UK Government Data Standards Catalogue]


<p>It would need to be able to determine precise amounts/units of each ingredient. This might turn out to be like the currency problem, or it might be more complex, given the variety of units used in recipes, English vs. metric etc. That's a case that might need a microformat. We need more research and analysis to really justify it, but I can see it within the realm of probable possibility.</p>
The [http://www.govtalk.gov.uk/gdsc/schemaHtml/FinancialTypes-v1-1-xsd-AmountSterlingStructure.htm associated XML Schema] seems to suggest an ''Amount'' element, followed by a fixed ''Currency'' element of "GBP".

== Brainstorming ==
The current price of a stock:

<p>Maybe something like...</p>


<pre>Pay me <abbr class="currency" title="CAD">$</abbr>5.00 now!</pre>
<pre><span class="pr">401.90</span></pre>


<p>Although something like the the following might be better...</p>
=== eBay ===
[http://www.ebay.com eBay].


<pre>Pay me <span class="money"><abbr class="currency" title="CAD">$</abbr>5.00</span> now!</pre>
eBay marks prices as "ebcPr". eBay c? Price.


<p>But it might be more semantic salt than is considered necessary.  Just having the abbr with the class-currency near a number might be good enough. But that's open for discussion though.</p>
<pre>
<td class="ebcPr"><span class="bold">$11.70</span><br/><span>$12.95</span><br/></td>
</pre>


=== Ben Ward ===
=== Google Web Authoring Statistics ===
<p>Could pure HTML be sufficient?</p>
[http://code.google.com/webstats/2005-12/classes.html Google Web Authoring Statistics] - indirect example.
<pre><html lang="en-gb">
<p>My new T-Shirts cost £30, but it cost my friend in Canada <span lang="en-ca">$34</span></p>
</html></pre>


===Arve Bersvendsen ===
The Google Web Authoring Statistics mentions that "price" is the 40th most used class name.
<pre><p lang="nb">Den kanadiske prisen på t-skjorten var <span class="currency CAD">34 $</span>.</p></pre>


=== Mike Stickel ===
Something like:
<pre><span class="money"><abbr class="currency" title="CAD eng">$</abbr><span class="amount">5.00</span></span></pre>
<p>In this format the wrapping would be "money" or something similar followed by either the actual "amount" or the "currency", depending on what rules your country/language follows in regards to the order. 
Since there can be a difference between different languages within countries I thought it might be a good idea to include that in the "currency" definition of the formating, eg., "CAD eng" or "CAD fr". 
It could also give sites that list multiple languages a way to differentiate when they show multiple prices.</p>


=== Ciaran McNulty ===
<pre>
<p>The only microformat that I've noticed currency units in is [[hListing]], and that deliberately shies away from parsing the actual values because it's too free-form in most existing Listing formats.</p>
<span class="price">$39.99</span>
</pre>


<p>My own preference would be for something like:</p>
=== McAfee ===
<pre><p class="money">This item costs
[http://us.mcafee.com/root/package.asp?pkgid=100 McAfee].
  <span class="currency">GBP</span>
  <span class="amount">10.00</span>
</p></pre>


<p>Which with similar parsing rules to existing formats would also allow things like:</p>
<pre><p class="money">
  It'll cost you
  <abbr class="currency" title="50.00">fifty</abbr>
  <abbr class="amount" title="GBP">quid</abbr>
  , mate!
</p></pre>
<p>Or, a more complex example with multiple languages:</p>
<pre>
<pre>
<p lang="en">Price:
<span class="price">$39.99 <span class="currency">(USD)</span></span>
<span class="money">
