 |
| RDF - the Resource Description Framework - is a standard way for simple descriptions to be made. What XML is for
 |
| syntax, RDF is for <strong>semantics</strong> - a clear set of rules for providing simple descriptive information. RDF
 |
| Schema then provides a way for those descriptions to be combined into a single vocabulary. RDF is integrated into a
 |
| variety of applications including:<br />
 |
| <br />
 |
| * library catalogs<br />
 |
| * world-wide directories<br />
 |
| * syndication and aggregation of news, software, and content<br />
 |
| * personal collections of music, photos, and events<br />
 |
| <br />
 |
| The RDF specifications provide a powerful framework for supporting the exchange of <strong>knowledge</strong> on the
 |
| Web.
 |
| </p>
 |
| <p>
 |
| What’s needed next is a way to develop subject - or domain - specific vocabularies. That is the role of an ontology. An
 |
| ontology defines the terms used to describe and represent an area of knowledge. Ontologies are used by people,
 |
| databases, and applications that need to share subject-specific (domain) information - like medicine, tool
 |
| manufacturing, real estate, automobile repair, financial management, etc. Ontologies include computer-usable
 |
| definitions of basic concepts in the domain and the relationships among them. They encode knowledge in a domain and
 |
| also knowledge that spans domains. In this way, they make that knowledge reusable.<br />
 |
| <br />
 |
| OWL - the Web Ontology Language - provides a language for defining structured, Web-based ontologies which delivers
 |
| richer integration and interoperability of data among descriptive communities. OWL uses both URIs for naming and the
 |
| description framework for the Web provided by RDF to add the following capabilities to ontologies:<br />
 |
| <br />
 |
| * Ability to be distributed across many systems<br />
 |
| * Scalability to Web needs<br />
 |
| * Compatibility with Web standards for accessibility and internationalization<br />
 |
| * Openess and extensiblility<br />
 |
| </p>
 |
| <p>
 |
| OWL and RDF implement an object-relational model allowing creation of a directed graph, a network of objects and
 |
| relationships describing data. It is possible to infere new information from OWL and RDF data. Ex: if a container is
 |
| for San Francisco then it is shipped to Oakland.
 |
| </p>
 |
| <p>
 |
| For Tim Berners-Lee who specifies the semantic web, rules constitute a key element of the semantic web, allowing
 |
| integration, derivation and transformation of the data from multiple sources in a distributes, transparent and scalable
 |
| manner.
 |
| </p>
 |
| <p>
 |
| Bringing semantic web into BPMS-BRMS practice offers rigou,rous data modeling combined with a rule engine to reason,
 |
| classify and improve data quality.
