Editing Semantic Web (section)

=== Doubling output formats ===
Another criticism of the semantic web is that it would be much more time-consuming to create and publish content because there would need to be two formats for one piece of data: one for human viewing and one for machines. However, many web applications in development are addressing this issue by creating a machine-readable format upon the publishing of data or the request of a machine for such data. The development of microformats has been one reaction to this kind of criticism. Another argument in defense of the feasibility of semantic web is the likely falling price of human intelligence tasks in digital labor markets, such as [[Amazon.com|Amazon]]'s [[Amazon Mechanical Turk|Mechanical Turk]].{{Citation needed|date=February 2015}}

Specifications such as eRDF and RDFa allow arbitrary RDF data to be embedded in HTML pages. The [[GRDDL]] (Gleaning Resource Descriptions from Dialects of Language) mechanism allows existing material (including microformats) to be automatically interpreted as RDF, so publishers only need to use a single format, such as HTML.
