+There

+recommends

+Microdata
+[

+MICRODATA
+</a>
+</cite>
+]
+is
+a
+way
+of
+embedding
+data
+in
+HTML
+documents
+using
+attributes.
+The
+HTML
+DOM
+is
+extended
+to
+provide
+an
+API
+for
+accessing
+microdata
+information,
+and
+the
+microdata
+specification
+defines
+how
+to
+generate
+a
+JSON
+representation
+from
+microdata
+markup.
+</p>
+<p>
+Mapping
+microdata
+to
+RDF
+enables
+consumers
+to
+merge
+data
+expressed
+in
+other
+RDF-based
+formats
+with
+microdata.
+It
+facilitates
+the
+use
+of
+RDF
+vocabularies
+within
+microdata,
+and
+enables
+microdata
+to
+be
+used
+with
+the
+full
+RDF
+toolchain.
+Some
+use
+cases
+for
+this
+mapping
+are
+described
+in
+<a href="#use-cases">
+Section
+1.2
+</a>
+below.
+</p>
+<p>
+Microdata's

+does
+not
+align

+with

+<ul>

+Non-URL
+microdata
+properties
+are
+disambiguated
+based

+an
+<a href="#dfn-item" class="internalDFN">
+item
+</a>
+with
+the
+type
+<code>
+http://example.org/Cat
+</code>
+can
+have
+both
+the
+property
+<code>
+color
+</code>
+and
+the
+property
+<code>
+http://example.org/color
+</code>,
+and
+these
+properties
+are
+semantically
+distinct
+under
+microdata.
+In
+RDF,
+all
+properties
+have
+IRIs.
+</li>
+<li>
+When
+an
+item
+has
+multiple
+properties
+with
+the
+same
+name,
+the
+values
+are
+always
+ordered;
+in
+RDF,
+property
+values
+are
+unordered
+unless
+they
+are
+explicitly
+listed
+in

+</li>
+<li>
+A
+value
+in
+microdata
+is
+always
+a
+simple
+string
+which
+is
+interpreted
+by
+the
+consuming
+application.
+In
+RDF,
+values
+can
+be
+tagged
+with
+a
+datatype
+or
+a
+language.
+According
+to
+the
+microdata
+specification,
+the
+HTML
+context
+of
+microdata
+markup
+should
+not
+change
+how
+microdata
+is
+interpreted,
+so
+although
+element
+names
+and
+HTML
+<code>
+@lang
+</code>
+attributes
+could
+be
+used
+to
+provide
+datatype
+and
+language
+information
+for
+RDF
+data,
+this
+would
+be
+contrary
+to
+the
+microdata
