  • Linked Data & Semantic Web Technology

    an elemental syntax

    for content structure

    within documents

    a simple language

    for expressing data models,

    which refer to objects ("resources")

    and their relationships

    more vocabulary

    for describing properties and classes

    a vocabulary for describing

    properties and classes

    of RDF-based resources

    a protocol and query

    language

    for semantic web data

    sources

    to exchange rules

    between many

    "rules languages"

    a string of characters used to identify a name or a resource

    RDF Serialization

    N-Triples RDF Test Cases, W3C Recommendation, 25 February 2014 a line-based, plain text serialization format for storing and transmitting RDF data

    Notation 3 (N3)

    a shorthand non-XML serialization of RDF models, designed with human-readability in mind

    much more compact and readable than XML RDF notation

    Turtle (Terse RDF Triple Language)

    W3C Candidate Recommendation, 25 February 2014 a format for expressing data in the Resource Description Framework (RDF) data

    model a subset of Notation3 (N3) language, and a superset of the minimal N-Triples format

    RDF/XML

    W3C Recommendation, 25 February 2014 an XML syntax for writing down and exchanging RDF graphs
