General information

Name	Inverse n-ary relationship

Author(s)	MariaPoveda, MariCarmenSuarezFigueroa

Description

Motivation	The n-ary relationships should be used when: (a) a binary relationship really needs a further argument; (b) two binary relationships always go together and should be represented as one n-ary relation; (c) a relationship that is really amongst several things. The motivation of this pattern is to express the inverse relationship of a n-ary one.
Aim	The aim of this pattern is to allow asking for n-ary relationships and its inverse without a complex query involving the class created to support the n-ary relation between the origin and destiantion classes of the n-ary relationship.
Solution description
Elements	Class, Relationship, Attribute and inverseOf
Implementation
Reusable component
Component type

Example

Problem example	We might want to represent that the service providers provide a service at a place in a given period of time with a price. Also is needed represent that a service is offered by a provider.
Pattern solution example	http://ontologydesignpatterns.org/wiki/Image:LP-IN-01v1.jpg
Consequences	The main advantage of this pattern is that allows to ask for which services are provided by a service provider and vice versa without a complex query involving the class created to support the n-ary relation between service providers and services.
