GRDDL step 1 declare a document is a source

GRDDL step 2 link it to one or more extractors

GRDDL step 3 let GRDDL agents extract RDF from the document

generic profile ,[object Object],<head profile="http://www.w3.org/2003/g/data-view" > <title>The man who mistook his wife for a hat</title> <link rel="transformation" href="http://www.w3.org/2000/06/ dc-extract/dc-extract.xsl" /> <meta name="DC.Subject" content="clinical tales" /> … </head>

custom profile declare a source and a transformation at once

XML document declare a source and a transformation for an

generic profile ,[object Object],<book xmlns="http://example.org/book/" xmlns:grddl="http://www.w3.org/2003/g/data-view#" grddl:transformation=" http://example.org/book/getAuthor.xsl " > <title>The man who mistook his wife for a hat</title> … </book>
