The idea of markup languages was apparently first publicly presented by the engineer William W. Tunnicliffe (1922-1996) from Washington, D.C. In September of 1967, during a meeting at the Canadian Government Printing Office, Tunnicliffe gave a presentation on the separation of information content of documents from their format.
The Resource Description Framework RDF allows you to describe web documents and resources from the real world—people, organisations, things—in a computer-processable way. Publishing such descriptions on the web creates the semantic web. URIs are very important as the link between RDF and the web. This article presents guidelines for their effective use.
Resource Description Framework (RDF) is a standard for describing resources on the web. This guide contains links to many RDF resources including examples, documents, software, tools and projects that use it.

PURLs (Persistent Uniform Resource Locators) are Web addresses that act as permanent identifiers in the face of a dynamic and changing Web infrastructure.
This document defines an XML syntax for RDF called RDF/XML in terms of Namespaces in XML, the XML Information Set and XML Base. The formal grammar for the syntax is annotated with actions generating triples of the RDF graph as defined in RDF Concepts and Abstract Syntax.
Is the RDF model an entity-relationship mode? Yes and no. It is great as a basis for ER-modelling, but because RDF is used for other things as well, RDF is more general. RDF is a model of entities (nodes) and relationships.
This document defines an abstract syntax on which RDF is based, and which serves to link its concrete syntax to its formal semantics. This abstract syntax is quite distinct from XML's tree-based infoset [XML-INFOSET]. It also includes discussion of design goals, key concepts, datatyping, character normalization and handling of URI references.

It`s not a Web of computers, it`s a Web of People.... Sir Timothy Berners-Lee, the inventor of the Web, is talking about the history of the Web and on the subject of Web Science
In March 1989, Tim Berners-Lee submitted a proposal for an information management system to his boss, Mike Sendall. ‘Vague, but exciting’, were the words that Sendall wrote on the proposal, allowing Berners-Lee to continue.
