Role Description
Responsibility
Payment Provider
Manages payment transactions on behalf of Owner.
NOTE: Payment Provider is only required if the terms and
conditions of the GeoLicence include a financial compensation
for the rights to access the specified Geospatial Resource.
Receives Licence fee payment details from Licensing Agent.
May maintain outstanding balances between Owner and
Licensees to be settled at a specified account period.
Licence Manager
Manages Licences on behalf of the Rights Managed network and
acts as a trusted third party between the Owner and the
Licensee. Registers new and updated
GeoLicences. Provides GeoLicence validation
functions to Service Provider.
Licensee Acquires rights to access a
Geospatial Resource. Terms and Conditions of those rights are
defined in the GeoLicence. Organisation or Individual with an
assigned set of rights as defined by the GeoLicence.
Rights granted by the GeoLicence may include the rights to sub-
license resource.
Sub-Licensee Acquires or is assigned a subset
of rights by the Licensee. Sub-licensee is assigned a subset
of the rights as defined by the GeoLicence.
End-User The individual person who
accesses the Geospatial Resource.
Accesses Geospatial resource based on the terms and conditions
of the GeoLicence.
GeoDRM design goal is to make the process of licence creation and
enforcement as transparent as possible to the End-User.
A key challenge for the GeoDRM Reference Model is to create an abstract rights model with defined roles and responsibilities, which may then be combined in different
configurations according to the specific needs of the business model.
8.2 Principals
Principals are the active entities of the systems: those that can initiate actions, such as requests. Most entities are associated to people and, by extension, to their presence on the
net or in the system, i.e., their computers, software or, at least, their identity.
One of the most common authorization tasks is the verification of identity of a principal.

Figure 14: Various Principals in a GeoDRM system
8.3 Resource owner
Owner principals are the controllers of the resources. The relationship between the Owner and the legal owner of a resource may be defined completely outside the system, such as
by legal contracts, etc., but the root or all rights resides in the legal owner, and the Owner principal is the legal owners presence or agent within the system.
8.4 Agent
Agent principals are principals allowed to act in the stead of another principal, usually supported by a licence to do so. This sort of licence is akin to the limited power of an
attorney in law, as it is seldom universal and will most likely restrict the acts of the agent to specific rights as contracted with the owner.
Most Agent principal subtypes will multiply inherit as interfaces from Agent and as appropriate for the rights allocated to him by the other principal. There may be no manner
for a user to distinguish whether he is working with and Agent or with the Licensor supporting the Agent’s licence to act. The Agent may have to present credentials to other
principals to prove their right to act as agent for a Principal with a separate identity.
