Core Data Model
Welcome » All things and their becoming » Techno Order (scope) » Model element » Object » Data Object » Core Data Model

A Core Data Model is an architectural building block of the EIRA Semantic view supporting the Semantic interoperability layer of the European Interoperability Framework.

Core Data Model is a specialisation of Data Object. It is a context-neutral data model that captures the fundamental characteristics of an entity or a core set of entities.

The Core Data Model ABB  is salient for technical interoperability because it supports semantic interoperability by providing simplified, reusable and extensible data models that capture the fundamental characteristics of a data entity in a context-neutral and syntax-neutral fashion.

Example

The following implementations is an example on how this specific Architecture Building Block (ABB) can be instantiated as a Solution Building Block (SBB).

ISA2 Core Vocabularies

Core Vocabularies are simplified, re-usable and extensible data models that capture the fundamental characteristics of an entity in a context-neutral fashion.
Public administrations can use and extend the Core Vocabularies in the following contexts:

  • Development of new systems: the Core Vocabularies can be used as a default starting point for designing the conceptual and logical data models in newly developed information systems.
  • Information exchange between systems: the Core Vocabularies can become the basis of a context-specific data model used to exchange data among existing information systems.
  • Data integration: the Core Vocabularies can be used to integrate data that comes from disparate data sources and create a data mash-up.
  • Open data publishing: the Core Vocabularies can be used as the foundation of a common export format for data in base registries like cadastres, business registers and service portals.
  • ISA² has developed the Core Vocabularies for public administrations in an open process with the active involvement of specific working groups.

The Core Vocabularies developed are the following:

  • Core Person: captures the fundamental characteristics of a person, e.g. name, gender, date of birth, location.
  • Core Business: captures the fundamental characteristics of a legal entity (e.g. its identifier, activities) which is created through a formal registration process, typically in a national or regional register.
  • Core Location: captures the fundamental characteristics of a location, represented as an address, a geographic name or geometry.
  • Core Public service: captures the fundamental characteristics of a service offered by a public administration.
  • Core Criterion and Core Evidence: describe the principles and the means that a private entity must fulfil to become eligible or qualified to perform public services. A Criterion is a rule or a principle that is used to judge, evaluate or test something. An Evidence is a means to prove a Criterion.
  • Core Public organisation: describes public organisations in the European Union.
