When XML is referred to as a meta-language, it means that XML is a language used to create other markup languages. Similar to a meta-language is metadata, which is data that is used to describe other data. XML relies heavily on metadata to add meaning to the content in XML documents. RDF and OWL are examples of XML vocabularies that expand on the concept of metadata by attempting to add meaning to web pages. |
