Core Data Model

A context-neutral data model that captures the fundamental characteristics of an entity or a core set of entities.

Based on Core Vocabularies Handbook…

The Core Data ABB is salient for semantic 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.

The following implementation 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.
- Registered organisation: 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.

- ID: Internal key used to identify an architecture building block
- dct:type: The type of the architecture building block
- dct:publisher: The name of the individual or organisation that is documenting the current building block
- dct:modified: The date that the information documented for this building block was last modified
- eira:url: The URL at which the specification can be referenced online
- eira:identifier: The identifier is unique. It identifies univocally the specification in the Cartography
- eira:body: The body contains statements on one or several Building Blocks. It informs either (i.e. proposed mode) on the proposed specification at the ABB level to achieve interoperability for its SBBs or (i.e. in solution descriptive mode) on a specification to which an SBB is actually compliant to achieve interoperability
- eira:domain: The domain can be either domain-neutral (not related to any public policy domain) or domain-specific to a given set of public policy domains. It informs on the public policy domain of application of the specification
