he current web is a decentralized platform for distributed presentations, while the SemWeb is a decentralized platform for distributed knowledge.
-
Resource Description Framework (RDF) is the W3C standard for encoding knowledge.
-
The real content, the knowledge the files are conveying to the human, is opaque to the computer.
-
What is meant by "semantic" in Semantic Web is not that computers are going to understand the meaning of anything, but that the logical pieces of meaning can be mechanically manipulated by a machine to useful human ends.
-
Files on the Semantic Web need to be able to express information flexibly.
-
Life can't be neatly packed into tables, as in relational databases or hierarchies, as in XML.

Files on the Semantic Web need to be able to relate to each other.
-
We will use vocabularies for making assertions about things, but these vocabularies must be able to be mixed together.

RDF was originally created in 1999 as a standard on top of XML for encoding metadata
-
Since then, and perhaps especially after the updated RDF spec in 2004, the scope of RDF has really evolved into something greater. The most exciting uses of RDF aren't in encoding information about web resources, but information about and relations between things in the real world: people, places, concepts, etc.

RDF was originally created in 1999 as a standard on top of XML for encoding metadata--literally, data about data. Metadata is, of course, things like who authored a web page, what date a blog entry was published, etc., information that is in some sense secondary to some other content already on the regular web. Since then, and perhaps especially after the updated RDF spec in 2004, the scope of RDF has really evolved into something greater. The most exciting uses of RDF aren't in encoding information about web resources, but information about and relations between things in the real world: people, places, concepts, etc.

Editor's Note: "What Is RDF" was originally written by Tim Bray in 1998 and updated by Dan Brickley in 2001. Recently it seemed like time for another update, particularly to relate RDF and the Semantic Web to the cutting edge of web development. We've republished the original in a new location and offer the following update. I'll leave to you, dear reader, the task of deciding how well Joshua Tauberer has accomplished the task of updating a classic. -- Kendall Grant ClarkBuilding the Semantic Web
On the Semantic Web (SemWeb), computers do the browsing (and searching, and querying, and...) for us. The SemWeb enables computers to seek out knowledge distributed throughout the Web, mesh it, and then take action based on it. Take an analogy: the current web is a decentralized platform for distributed presentations, while the SemWeb is a decentralized platform for distributed knowledge. Resource Description Framework (RDF) is the W3C standard for encoding knowledge.
