Other RDF-Related Technologies: Microformats, RDFa, and GRDDL
So far at this point, we have learned the concept of the Semantic Web, and we have learned RDF. Let us think about these two for a moment.
Recall that the vision of the Semantic Web is to add meaning into the current Web so machines can understand its contents. Based on what we have learned about RDF, we understand that RDF can be used to express the meaning of a Web document in a machine-processable way. More specifically, for a given Web document, we can create a set of RDF triples to describe its meaning and somehow indicate to the machine that these RDF statements are created for the machine to understand this document.
