 +====== SBVRwiki - business rules in wiki with SBVR ======
  
 +It is an online collaborative solution that allows for distributed and incremental business rules (//set of rules definig how does a company works//) authoring for business analytics and users.
 +It uses the Dokuwiki back-end for storage and unlimited version control, as well as user authentication.
 +It supports creation of vocabularies,​ terms and rules in a transparent,​ user friendly fashion.
 +Furthermore,​ it provides visualization and evaluation mechanisms for created rules.
 +It is integrated with the Loki knowledge engineering platform that allows for on-the-fly conversion of the SBVR rule base and vocabularies to Prolog.
 +
 +Business rules in SBVRwiki are written down according to SBVR standard. What is it?
 +
 +===== Definition =====
 +
 +[[http://​www.omg.org/​spec/​SBVR/​|SBVR]] (Semantics of Business Vocabulary and Business Rules) is a standard
 +for capturing expressive business rules, commonly perceived as a useful tool in
 +the communication between business analytics and business people. The set of
 +vocabularies and rules described with the use of SBVR can be an important part
 +of requirements specification from the software engineering methodologies.
 +
 +===== Characteristics =====
 +
 +  * business rules
 +  * semantics
 +  * hierarchical definitions
 +  * synonims/​abbriviations/​other languages
 +  * formal definitions based on concepts from dictionary
 +  * rules devided into two definitions
 +    - behavioral (commitments) - employees'​ actions
 +    - definitional (needs) - resources organisation
 +
 +===== Notation =====
 +
 +SBVR allow users to create complex models of business rules in Structured English.
 +
 +==== Styles ====
 +
 +  * Prefixed Rule Keyword Style
 +
 +^Behavioral (operational)^Definitional (structural)^
 +|It is obligatory that ...|It is necessary that ...|
 +|It is prohibited that ...|It is impossible that ...|
 +|It is permitted that ...|It is possible that ...|
 +
 +  * Embedded (mixfix) Rule Keyword Style
 +
 +^Behavioral (operational)^Definitional (structural)^
 +|... must ...|... always ...|
 +|... must not ...|... never ...|
 +|... may ...|... sometimes ...|
 +
 +==== Expressions ====
 +
 +Threre are four types of expressions in SBVR, every one has its different formatting and style (see examples in sections :terms :facst and :rules) :
 +
 +  * **term** -- noun concepts which should start with a lower case letter and be defined in singular from
 +  * **Name** -- proper names which are used in dictionary and rules and usually starts with upper case letter
 +  * **verb** -- verb concepts which has singular form in facts and plural in facts and rules
 +  * **keywords** -- SBVR notation which are used to construct sentences
 +
 +==== Keywords ====
 +
 +{{ .:​keywords.png?​600 |}}
 +
 +===== Logic =====
 +
 +Logic of SBVR relies mostly on first-order predicate logic with some limited extensions of higher-order logic and modal logic.
