Notation3. Notation3, or N3 as it is more commonly known, is a shorthand non-XML serialization of Resource Description Framework models, designed with human-readability in mind: N3 is much more compact and readable than XML RDF notation.
The format is being developed by Tim Berners-Lee and others from the Semantic Web community. A formalization of the logic underlying N3 was published by Berners-Lee and others in 2008. Examples This RDF model in standard XML notation <rdf:RDF xmlns:rdf=" xmlns:dc=" rdf:about=" Benn</dc:title><dc:publisher>Wikipedia</dc:publisher></rdf:Description></rdf:RDF> Turtle (syntax) Turtle (Terse RDF Triple Language) is a format for expressing data in the Resource Description Framework (RDF) data model with the syntax similar to SPARQL. RDF, in turn, represents information using "triples", each of which consists of a subject, a predicate, and an object.
Each of those items is expressed as a Web URI. Turtle provides a way to group three URIs to make a triple, and provides ways to abbreviate such information, for example by factoring out common portions of URIs. Turtle - Terse RDF Triple Language. Abstract The Resource Description Framework (RDF) is a general-purpose language for representing information in the Web.
This document defines a textual syntax for RDF called Turtle that allows RDF graphs to be completely written in a compact and natural text form, with abbreviations for common usage patterns and datatypes. Turtle provides levels of compatibility with the existing N-Triples and Notation 3 formats as well as the triple pattern syntax of the SPARQL W3C Proposed Recommendation. Resource Description Framework - Wikipedia, the free encyclopedi. The Resource Description Framework (RDF) is a family of World Wide Web Consortium (W3C) specifications  originally designed as a metadata data model.
It has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources, using a variety of syntax notations and data serialization formats. It is also used in knowledge management applications. Resource Description Framework. Semantic Web Stack. Semantic Web Stack The Semantic Web Stack, also known as Semantic Web Cake or Semantic Web Layer Cake, illustrates the architecture of the Semantic Web.
Overview The Semantic Web Stack is an illustration of the hierarchy of languages, where each layer exploits and uses capabilities of the layers below. It shows how technologies that are standardized for Semantic Web are organized to make the Semantic Web possible. Théorie des graphes. RDF and OWL. Introduction To The Semantic Web. Gleaning Resource Descriptions from Dialects of Languages - Wiki. Microformats Hop on Semantic Web 'Griddle' - InternetNews.com. There are a lot of different ways to connect the dots of content and data that comprise the Web.
Two of them are microformats Both approaches have attempted to make sense of content by making use of metadata descriptors, but they differ somewhat. The World Wide Web Consortium (W3C) is trying to change that.
