2 thoughts on “The Truth About Metadata

  1. Some footnotes:

    Hayes, P. (2004) RDF Semantics. http://www.w3.org/TR/rdf-mt/
    “Model theory assumes that the language refers to a ‘world’, and describes the minimal conditions that a world must satisfy in order to assign an appropriate meaning for every expression in the language. A particular world is called an interpretation, so that model theory might be better called ‘interpretation theory’. The idea is to provide an abstract, mathematical account of the properties that any such interpretation must have, making as few assumptions as possible about its actual nature or intrinsic structure, thereby retaining as much generality as possible. The chief utility of a formal semantic theory is not to provide any deep analysis of the nature of the things being described by the language or to suggest any particular processing model, but rather to provide a technical way to determine when inference processes are valid, i.e. when they preserve truth.”

    As usual, the Stanford Encyclopedia of Philosophy is also useful in exploring the more formal aspects of metadata semantics:
