What the Heck is Hyperdata?
Internet professionals are connecting a lot more of the digital dots these days thanks to Hyperdata.
In much the same way that a hypertext link describes what a user (and search engine) will find on another website, hyperdata is actually a more general term that refers to the linking that occurs within the Semantic Web specifically (and is often applied to data-linking technologies such as Microformats).
A hypertext link only indicates that a link exists between two documents. Hyperdata links/connections, however, go far beyond that to express semantics about the type of connection. For example, in a document about Tom Hanks, a hypertext link might be made from the word "actor" to a document about Hollywood movie stars. In contrast, a hyperdata link from the same word, to the same document, could "also" include one of the actor's movies, or movie roles, (depending on the ontology being used to define this link).
If you're familiar with the use of rich markup, microformats and Schema.org, you're well on your way to achieving success with Hyperdata on the Semantic Web.
