The Gist Accounting Ontology

Resource

   "A source or supply from which benefit is produced, typically a limited amount" (Wikipedia). The Resource category group all the concepts corresponding to what is sold. Often the resource to be sold is an asset which is defined by Wikipedia as any resource owned by a business.

• Resource or Requirement

   Most of the time, the resource is a physical object. However, often, the resource to be sold is a physical device not yet built or a service. In that case, we define the resource by a set of requirements.
note:
   The GIST ontology already defines this concept for you as "a documented physical or functional need that a particular design, product, or process must be able to perform. Alternately, the obligation of a person or organization to behave in a certain way (i.e., drive on the right side of the road)".

•   Person or Organization

   The resource is sometimes also about the person or an organization who is temporary going to work for another company. A typical example is a consultant.

State

   It defines the scope of possible actions to be performed with or on a certain Resource.

• Possession

   It defines the concept of physically possessing but not necessarily owning a Resource. This limit the scope of possible actions on the resource since it is not owned.

• Ownership

   It defines the concept of owning a Resource but not necessarily physically possess it. Especially, it provides the ability to dispose of it.

Event

   It defines something happening in a point or a period.

• Offer

   It defines the concept of a person or an organization making an offer, basically proposing a resource or a future service in return for money.

• Purchase

   It defines the concept of a person or an organization accepting an offer; then it becomes a purchase. This one can be preceded by a negociation occuring during a certain period.

• Movement

   It defines the change of possession or location without the change of ownership. It is usually a physical change of location.

• Transfer

   It defines the change of ownership without the change of possession.

• Allocation

   It defines a movement which does not affect any other accounting component. Typically the allocation of money on a balance sheet for tax optimization.

   It defines a responsibility, an obligation. It could be expressed financially.

• Obligation to pay

   A purchase triggers an obligation to pay for the buyer. It becomes a liability to him

• Obligation to deliver
