Right to Use Resources

Description

Bob Haugen:

"Features and Rights:

The term resource has two flavors; the rights associated with the resource and the features the resource has. Both the rights and the features have certain values for the economic agents.

In the application model (an instance of the model in Fig. 7), it is usually intuitive to model features as attributes of the resource entities, see for example Fig. 8. In the approach we follow in this book these attributes will be implemented as aspects, such as value aspect (see part two of the book).

Resource can also be seen as a collection of certain rights associated with this resource: ownership rights, usage rights, copy-rights.

Purpose of the exchange process is to transfer some of the rights associated to the resource from the provider economic agent to the recipient economic agent.

The model for resource rights has different structure than the model for resource features. The main reason is that while resource features can change on their own, the rights an economic agent has to the resource can be changed only by economic events. Therefore, it is necessary to store the features on the resource, while rights are determined by relationships to the economic events..

Discussion

Bob Haugen:

"below from the REA Patterns book (Pavel Hruby and Christian Scheller, hereafter called P&C):

In this book, we follow the approach in which the stockflow relationships at the application model level determine the rights transferred from one business agent to another.

The other possible approaches to modeling rights are:

• Rights are properties of resources. • Rights are components of resources, attached to the "main" resource to which they give rights. [In this approach, rights are also resources.] • Rights are properties of stockflow relationships between economic resources and economic events. [This is what they describe above…] • Rights are types of commitments. • Rights are refinements of the custody relationship between economic agents and economic resources. • Rights are defining characteristics of events.

All approaches have their advantages and disadvantages, and also combinations of these approaches maybe possible." (https://docs.google.com/document/d/1mFnWLuYWpZ-UL-aIgA-I5dvBmgqJco_1S8ljXXXww4g/edit)
