  • Syntactic construction. That it build defines the fresh elements to have indicating the new certified presentation syntax of RIF reason languages by the focusing the brand new speech sentence structure of one’s framework. The fresh new speech syntax is utilized from inside the RIF so you can identify the newest semantics of the languages and also to train part of the details with examples. This syntax isn’t intended to be a tangible sentence structure to own this new dialects; it leaves out facts for instance the delimiters of the numerous syntactic areas, parenthesizing, precedence out of workers, and stuff like that. Once the RIF are an interchange style, they spends XML as the merely real syntax.
  • Semantic structure. New semantic build means the fresh new systems which might be utilized for indicating the brand new different types of RIF logic languages.
  • XML serialization build. This build defines the general prices you to definitely reasoning languages are to use in indicating their real XML-mainly based syntaxes. For every dialect, their tangible XML syntax are a by-product of the dialect’s presentation sentence structure. It could be recognized as an effective serialization of these sentence structure.


  • Constants and you will details. These terminology are common to most logic languages.
  • Positional terminology. These terms and conditions are generally utilized in earliest-buy logic. RIF-FLD represent positional terms and conditions inside a slightly way more general ways in buy to enable languages with large-buy sentence structure, such as for instance HiLog [CKW93] and you will Relfun [RF99].
  • Words that have called objections. These are such as positional terms and conditions aside from for every disagreement away from a beneficial name is known as therefore the buy of arguments is actually immaterial. Words having entitled objections generalize the thought of rows in relational tables, in which line headings correspond to disagreement labels.
  • Listings. Such terms match listings from inside the logic programming, and tend to be utilized in the basic Logic Dialect. Limited sizes ones conditions can be used on the Key Dialect therefore the Manufacturing Legislation Dialect.
  • Structures. A-frame title is short for an assertion throughout the an object and its particular services. This type of terms and conditions correspond to particles out-of F-reasoning [KLW95]. There is syntactic resemblance anywhere between terms and conditions with named objections and you can structures, just like the properties (otherwise features) regarding an object resemble called arguments. However, the latest semantics of them terminology differ (discover Section Semantic Formations).
  • Class. Such conditions are widely used to describe the subclass and you may group registration relationships. There have been two kinds of class conditions: subscription terminology and subclass conditions. Such as for instance frames, these words was in fact borrowed off F-reasoning [KLW95].
  • Equality. These words are used to associate almost every other terminology.

pred:numeric-equal or pred:boolean-equal). Those predicates have fixed interpretations, which coincide with the interpretation of the equality terms defined in this document when the latter are evaluated over data types. General use of equality terms is supported in systems such as FLORA-2 [FL2], and special cases are also allowed in Relfun [RF99].

Terms are then used to define several types of RIF-FLD formulas. RIF dialects can choose to permit all or some of the aforesaid categories of terms. In addition, RIF-FLD introduces extension points, one of which allows the introduction of new kinds of terms. An extension point is a keyword that is not a syntactic construct per se, but a placeholder that is supposed to be replaced by specific syntactic constructs of an appropriate kind. RIF-FLD defines several types of extension points: symbols (NEWSYMBOL), connectives (), quantifiers (NEWQUANTIFIER), aggregate functions (NEWAGGRFUNC), and terms (NEWTERM).

Although not, beyond your analysis systems, the new interpretation of one’s equality terms and conditions may vary that’s determined because of the contents of RIF documents

Symbol areas partition the fresh group of low-analytical symbols you to match individual constants, predicates, and procedures, and each partition will be offered its very own semantics. A symbol room features a keen identifier and a good lexical area, and this talks of the brand new “shape” of your symbols where symbol room. Some symbol rooms from inside the RIF are widely used to select Web organizations and their lexical area includes strings that syntactically appear to be internationalized financing identifiers [RFC-3987], otherwise Eye (elizabeth.g., Most other icon room are used to represent the latest datatypes necessary for RIF (eg,
