The REWERSE Rule Markup Language (R2ML) is developed by the REWERSE Working Group I1 for the purpose of rules interchange between different systems and tools.

01Scope

  • An XML based rule language;
  • Support for: integrity rules, derivation rules, production rules and reaction rules;
  • Integrate functional languages (such as OCL) with Datalog languages (such as SWRL);
  • Serialization and interchange of rules by specific software tools;
  • Integrating rule reasoning with actual server side technologies;
  • Deploying, publishing and communicating rules in a network.

02Design principles

  • Modeled using MDA;
  • Rule concepts defined with the help of MOF/UML;
  • Required to accommodate:
    • Web naming concepts, such as URIs and XML namespaces;
    • The ontological distinction between objects and data values;
    • The datatype concepts of RDF and user-defined datatypes;
  • Actions (following OMG PRR submission);
  • Events;
  • EBNF abstract syntax;
  • XML based concrete syntax validated by an XML Schema;
  • Allowing different semantics for rules.

Ontology (information science)

In information science, an ontology encompasses a representation, formal naming, and definitions of the categories, properties, and relations between the concepts, data, or entities that pertain to one, many, or all domains of discourse. More simply, an ontology is a way of showing the properties of a subject area and how they are related, by defining a set of terms and relational expressions that represent the entities in that subject area.

Business rule

A business rule defines or constrains some aspect of a business. It may be expressed to specify an action to be taken when certain conditions are true or may be phrased so it can only resolve to either true or false.

Business rules approach

Business rules are abstractions of the policies and practices of a business organization. In computer software development, the business rules approach is a development methodology where rules are in a form that is used by, but does not have to be embedded in, business process management systems.
