The Resource Description Framework
The Resource Description Framework (RDF) is a language for representing information about things (metadata) that can be identified on the Web, even when they cannot be directly retrieved on the Web.
A W3C standard2

Metadata
A metadata record consists of a set of attributes, or elements, necessary to describe the resource in question.

RDF basics
Information is a collection of statements, each with a subject,verb and object - and nothing else.
Everything, be it subject,verb or object, is identified with a Uniform Resource Identifier. One exception; a object can be a literal (string, integer,..)

subject,verb and object
S: <http://www.terena.nl/friend#roland>V: <http://www.openmetadir.org/om/0.1/element#knows> O: <http://www.terena.nl/friend#diego> .
Everything is identified by a URI The verb is also known as a predicate and what you use as a predicate is a propertyDon’t forget the ‘.’

OWL
The OWL Web Ontology Language is intended to provide a language that can be used to describe the classes and relations between them that are inherent in Web documents and applications.
13
![Page 14: The Semantic Web meets Resource Management · Terena EuroCAMP, 2006-04-03 RDF 101 The Semantic Web meets Resource Management 1](https://reader034.vdocument.in/reader034/viewer/2022051919/600c51c87c482c206f5e9e74/html5/thumbnails/14.jpg)
The Web Ontology Language (OWL)
supports
Sharing information and knowledge (for interoperability)Defining the relationships between different resourcesUnderstanding of the domainRepresentation of conceptualization

![Page 15: The Semantic Web meets Resource Management · Terena EuroCAMP, 2006-04-03 RDF 101 The Semantic Web meets Resource Management 1](https://reader034.vdocument.in/reader034/viewer/2022051919/600c51c87c482c206f5e9e74/html5/thumbnails/15.jpg)
!!!
An ontology differs from an XML schema in that it is a knowledge representation, not a message format
15
![Page 16: The Semantic Web meets Resource Management · Terena EuroCAMP, 2006-04-03 RDF 101 The Semantic Web meets Resource Management 1](https://reader034.vdocument.in/reader034/viewer/2022051919/600c51c87c482c206f5e9e74/html5/thumbnails/16.jpg)
An oncology encompasses four concepts
ClassesRelationship between classesProperties of classesConstrains on relationship between the classes and properties of the classes

OWL types
OWL Lite; Supports simple classifications, allowing only cardinalities of 0 and 1 and only minimal constrains.OWL DL; Supports more complex ontologies, but with some guarantees, such as processing finishing in finite time.OWL Full; maximum freedom of RDF, with no computational guarantees.

Basic Elements
The most basic concepts in a domain should correspond to classes that are the roots of various taxonomic trees.Properties let us assert general facts about the members of classes and specific facts about individuals.An individual is minimally introduced by declaring it to be a member of a class

Simple properties
A property is a binary relation. Two types of properties are distinguished:datatype properties, relations between instances of classes and RDF literals and XML Schema datatypes.object properties, relations between instances of two classes.

Property restrictions
In addition to designating property characteristics, it is possible to further constrain the range of a property in specific contexts in a variety of ways.

RDF and Identity/Resource
ManagementMiddleware is a lot about managing objects/resources more specifically metadata about those.Identity management just one partIf you want to future-proof your investment don’t chose a limiting frameworkAnd for godness sake describe your knowledge representation !
