Buzzword.org.uk Draft: RDF Extracted Attributes from Styled Elements

Description

some rights reserved

GRDDL provides a powerful and robust mechanism for extracting RDF triples from XHTML, and more generally any XML-based markup. By introducing an initial “tidying” stage beforehand, GRDDL can also be applied to HTML. GRDDL enables documents authored using the XHTML attribute and other semantic XHTML techniques to be transformed to a more formal knowledge representation.

The GRDDL recommendation allows for transformations to be written in any programming language, but only documents the use of XSLT transformations in detail. XSLT is a full Turing-complete programming language, far more powerful and complex than necessary for most GRDDL use cases.

This document describes a simple new document description language “RDF-EASE”, with a familiar syntax that borrows heavily from Cascading Style Sheets (CSS). The document also describes how RDF-EASE can be used as a transformation language for the purpose of GRDDL.

This document is published by buzzword.org.uk, a web site that hosts various specifications, articles and tools of use to web publishers. This is not a W3C recommendation. It is not even a buzzword.org.uk recommendation yet.

1. Introduction

This section is informative.

Ten second sales pitch: CSS is an external file that specifies how your document should look; RDF-EASE is an external file that specifies what your document means

This document introduces a document description language called “RDF-EASE”, which may be used to transform an XHTML document to RDF triples.

It is intended to act as an alternative to XSLT in the context of GRDDL. XSLT’s functional programming style can make it tricky for a programmer more accustomed to procedural programming ...
