  • Syntactic build. That it structure defines the latest elements having indicating the fresh new official demonstration sentence structure away from RIF reasoning dialects by concentrating the brand new presentation sentence structure of one’s construction. The brand new presentation sentence structure can be used inside RIF to define new semantics of languages and teach the main facts which have instances. That it sentence structure is not supposed to be a concrete sentence structure having the fresh dialects; it leaves away information such as the delimiters of the numerous syntactic section, parenthesizing, precedence away from providers, etc. Given that RIF is actually a keen interchange structure, it uses XML as the just concrete syntax.
  • Semantic construction. The newest semantic construction describes brand new mechanisms which can be used in specifying the new models of RIF reasoning dialects.
  • XML serialization design. That it construction represent the entire principles one logic dialects should be include in indicating its real XML-mainly based syntaxes. For every dialect, the tangible XML syntax try a by-product of the dialect’s speech syntax. It could be named a good serialization of these syntax.

NEWCONNECTIVE

  • Constants and variables. This type of words are common to many reasoning languages.
  • Positional terms. These conditions are generally found in very first-acquisition reason. RIF-FLD represent positional terms and conditions within the a somewhat a lot more standard means inside order to enable languages that have higher-order syntax, like HiLog [CKW93] and you may Relfun [RF99].
  • Words that have called arguments.
