RDF triple notation

Terms from Artificial Intelligence: humans at the heart of algorithms

The glossary is being gradually proof checked, but currently has many typos and misspellings.

RDF is expressed using subject-predicate-object triples, where both the subject and predicate have to be URIs, but the object may also be some form of literal value such as a number or string. This allows one to express statements such as:
      <https://alandix.com/academic/> <ex:is_about> "Alan Dix".
The abstract triples may be represented in a number of concrete syntaxes, some more compact, some easier for human or computer processing.
