The GEA Object Model for Service Provision or Public Service Model is an in-depth analysis of the service provision process.
The Public Service Model is depicted in Figure 1.
Figure 1: The GEA Public Service Model
This model is of particular importance for eGovernment applications and implementations as it could serve as the conceptual basis for constructing a public administration service ontology. The model presented here is PA domain-specific and as such takes into account, captures and expresses the semantics of the particular domain. At the same time, it remains basically compatible to the core concepts of generic service ontologies like OWL-S and WSMO. Being a generic PA model, the service description presented here may cover many different (ideally all) application areas in public administration. This makes it highly reusable in different cases of public service provision.
There are two categories of Governance Entities participating in service provision:
Societal Entities model citizens, business or NGOs.
Preconditions set the general framework in which the Public Service should be performed and the underlying business rules that should be fulfilled for its successful execution. Preconditions can be formally expressed as a set of clauses (or rules) and are validated by a Piece of Evidence serving a Purpose. As Evidence is pure information, it is stored in Evidence Placeholders (e.g. administrative documents).
The Outcomerefers to the different types of results a Public Service may have. The Public Service Model defines three types of Outcome:
Public Services are provided at an Administrative Level, i.e. local, regional, national, pan-European.
Public Services are categorized in several Domains, i.e. transportation, social welfare. Each Domain is divided into several SubDomains, i.e. the Transportation domain has SubDomains Ground Transportation, Air Transportation etc.
