I'm using schema.org definition to represent a product. I have a doubt about product size: should I specify the unit of measure in the field?
Here's my code (I need a separate span
for "cm" to style it differently):
<div itemscope itemtype="http://schema.org/Product">
<h1 itemprop="name">Product name</h1>
Size:
<span itemprop="width">60 <span>cm</span></span>
<span itemprop="height">50 <span>cm</span></span>
<span itemprop="depth">40 <span>cm</span></span>
</div>
Is this the correct way to define the size?
The width
/depth
/height
properties expect Distance
or QuantitativeValue
as value.
If you want to use Distance
:
As the Distance
type does not seem to define a suitable property to provide the actual value, and its description says that values have
[…] the form '<Number> <Length unit of measure>'. E.g., '7 ft'.
I assume that the type should not be provided explicitly, e.g.:
<span itemprop="width">
60 <span>cm</span>
</span>
If the type should be provided, I guess using name
is the only option:
<span itemprop="width" itemscope itemtype="http://schema.org/Distance">
<span itemprop="name">60 <span>cm</span></span>
</span>
If you want to use QuantitativeValue
:
<span itemprop="width" itemscope itemtype="http://schema.org/QuantitativeValue">
<span itemprop="value">60</span>
<span>cm</span>
<meta itemprop="unitCode" content="CMT" />
</span>
Instead of specifying the UN/CEFACT code for "cm" (= CMT
) in a meta
element (which is allowed in the body
, if you use it for Microdata), you could also use the data
element:
<span itemprop="width" itemscope itemtype="http://schema.org/QuantitativeValue">
<span itemprop="value">60</span>
<data itemprop="unitCode" value="CMT">cm</data>
</span>
