Web Sémantique:RDF. RDF - Semantic Web Standards. Overview RDF is a standard model for data interchange on the Web.
RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. RDF extends the linking structure of the Web to use URIs to name the relationship between things as well as the two ends of the link (this is usually referred to as a “triple”). Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications.
This linking structure forms a directed, labeled graph, where the edges represent the named link between two resources, represented by the graph nodes. Tutorial 2: Introducing RDF/XML. Next: Semantic Modeling If the graph data model is the model the semantic web uses to store data, RDF is the format in which it is written.
In the first lesson, we looked at graph data and introduced RDF.
