What is the CPSV-AP

The Core Public Service Vocabulary Application Profile (CPSV-AP) is a data model that has been developed in the context of a Working Group for describing public services. 

The main focus of the CPSV-AP version 1.00 was the description of public services and business events on the Points of Single Contact which each Member State had to implement in the context of the Services Directive (2006/123/EC). 

Throughout 2016, the scope of the data model was extended to cover any type of public services. This work focused ultimately on improving and harmonising the provision of information about public services on established eGovernment portals, taking into account the user-centric perspective, i.e. citizens and businesses.

Version 2.0 has been reviewed by the Working Groups Members, leading to the publication of CPSV-AP v2.1. The update finds its motivation in the experience of implementing version 2.0 of the CPSV-AP by different MSs and stakeholders and consequent requests received from them, such as the addition of the concept of catalogue to cover the metadata of the origin of the sources of those public service descriptions that are collected into a common database (decentralised approach).

The CPSV-AP has been seen as a first step for creating a model for describing public services related to business and life events, to facilitate the set-up of catalogues of services oriented to businesses and citizens. The CPSV-AP has been defined as an Application Profile of the ISA² Core Public Service Vocabulary (CPSV). 

Core Vocabulary is a simplified, reusable and extensible data model that captures the fundamental characteristics of an entity in a context-neutral fashion. Core Vocabularies are the starting point for agreeing on new semantic interoperability assets and defining mappings between existing assets to guarantee a level of cross-domain and cross-border interoperability that can be attained by public administrations.

All the versions of the Core Vocabularies can be downloaded from https://joinup.ec.europa.eu/solution/e-government-core-vocabularies.

An Application Profile is a specification that re-uses terms from one or more base standards, adding more specificity by identifying mandatory, recommended and optional elements to be used for a particular application, as well as recommendations for controlled vocabularies to be used.

Process & Methodology

The handling of change requests follows the process described in "Change management release and publication process for structural metadata specifications developed by the ISA² programme".

The approach for the revision and extension of the CPSV-AP is based on the "Process and Methodology for Developing Core Vocabularies".

Known reuse of the CPSV(-AP)

Integrated portfolio management of public services. The Estonian Ministry of Economic Affairs created an extension of the CPSV to address local needs, as well as to cover the public service lifecycle. New classes and properties were introduced to cover information related to security, evaluation and the underlying Web Service(s) supporting the delivery of a public service. The extended CPSV is also the basis for the Estonian framework for the dynamic management of public service portfolios (focused on the evaluation of public services and the governance of their lifecycle).
The City of Ghent is currently publishing RDF in line with CPSV for local products.
In the context of the Business Lifecycle domain  of eSENS, a work on the mapping of criteria and evidences is being under development. More specifically the mapping of requirements and evidences between the Greek, Spanish and Polish activity registration procedure for sanitary and tourism services provision is considered. The relative procedures and requested input have initially been described according to the CPSV-AP model.

Motivation and use cases


Manage portfolios of public services

The use of a common data model, such as the CPSV-AP, provides a standardised way of documenting public services and business events for grouping these public services.

Publication of descriptions of business events and related public services

A common data model for business events and public services, such as the CPSV-AP, enables the flexible exchange and integration of the different public service descriptions and facilitates the publication of this information on the point of single access.

Finding information about public services more easily

A common data model for describing public services and making it possible to group them logically into business and life events, such as the CPSV-AP, would assist public authorities in providing high-quality descriptions of public services from a user-centric perspective.

Build user-centric catalogues of public services at all levels from regional to a European federated catalogue

The use of a common data model such as the CPSV-AP for describing business and life events, and related public services, enables the flexible exchange and integration of service descriptions between the national/regional authorities and pan-European one-stop-shops.



Several tools have have been developed in the context of Action 2016.29 Catalogue of Services of the ISA² Programme. These solutions are open-source tools that facilitate creating, validating, harvesting and exchanging public service descriptions that comply with the CPSV-AP. The tools are fully reusable and easily adaptable to, for example, other data models, business contexts, etc.
