Welcome to SEMIC! The Semantic Interoperability Community (SEMIC) is a vibrant network of experts and practitioners dedicated to advancing semantic interoperability across Europe. Our mission is to enhance the sharing and reuse of data and services, supported by SEMIC specifications, innovative pilots, and a rich knowledge hub. Join us in shaping the future of seamless data exchange!
The SEMIC action started under the former ISA and ISA² Programme, which evolved into the Interoperable Europe programme, an initiative by the European Commission.

Core Vocabularies and their Application Profiles
| Specification | Description |
|---|---|
|
|
The Core Business Vocabulary (CBV) is a simplified, reusable and extensible data model that captures the fundamental characteristics of a legal entity, e.g. the legal name, the activity, address, etc. |
|
|

|
|
The Core Person Vocabulary (CPV)is a simplified, reusable and extensible data model that captures the fundamental characteristics of a person, e.g. their name, their gender, their date of birth, their address, etc. |
|
|

The Core Vocabulary glossary is the name space containing all the terms defined and used in the Core Vocabularies. |
DCAT-AP & its extensions
| Application Profiles | Description |
|---|---|
|
|
BRegDCAT-AP is an extension of DCAT-AP for describing base registries. It interconnects public services with base registries and their associated services. |
|
|
The Data Catalogue Vocabulary Application Profile (DCAT-AP) is a specification for metadata records, enhancing semantic interoperability across European data portals. Based on W3C's DCAT, it supports standardised dataset descriptions, enabling efficient data exchange and reuse. |
|
|
GeoDCAT-AP is an extension of DCAT-AP for describing geospatial datasets, dataset series and services. |
|
|
MLDCAT-AP is an extension of DCAT-AP for describing machine learning models, together with their datasets, quality measured on the datasets and citing papers. |
|
|
STATDCAT-AP is an extension of DCAT-AP for describing statistical datasets. |
Other semantic specifications
| Other semantic specifications | Description |
|---|---|
|
|
ADMS is a vocabulary for describing interoperability assets, enhancing their discoverability for ICT developers by standardising metadata for easier exploration and access. |
|
|
ADMS-AP extends the use of ADMS for the description of other types of interoperability solutions, meaning solutions covering the political, legal, organisational and technical interoperability layers. |
|
|
A DCAT-AP Feed is a Linked Data Event Stream with containing ActivityStream entities Create, Update and Delete, about the DCAT-AP entities in a catalog. |
|
|
Linked Data Event Streams (LDES) is a technical standard that applies linked data principles to data streams. |
|
|
The SDG Search Service model enables competent authorities to use common metadata to structure their public services, independently from the level of granularity or complexity of these services. |
|
|
STR-AP is an Application Profile for harmonising and streamlining the framework for data generation and data sharing on short-term accommodation rental services across the EU. |

The SEMIC Style Guide defines the style guide to be applied to the SEMIC’s semantic data specifications, notably to the eGovernment Core Vocabularies and Application Profiles. It provides rules on naming conventions, syntax, artefact management and organisation. It is meant to be complemented with technical artefacts and implementations that enable automatic conformance checking and transformation of conceptual models into formal semantic representations. The HTML representation of the SEMIC Style Guide can be found here.
The SEMIC Core Vocabularies Handbook explains the usage of the SEMIC Core Vocabularies (CV) in a easy and transparent way. It is meant for business users who want to understand where the Core Vocabularies can be useful, and for semantic engineers who seek straightforward guidance suitable to specific use cases. A new version of the SEMIC Core Vocabularies is under development and can be found here.
This GitHub page contains all the SEMIC repositories. This includes the semantic assets such as Core Vocabularies & Application Profiles, but also internally developed tools, pilots, and much more.
The Governance repository is used to share policies, governance, maintenance, and communications with the community. What is expressed in this repository is applicable to all repositories, unless equivalent documents are explicitly mentioned or included in the respective repository.
The issue sections of the relevant repositories can be used to post questions regarding certain semantic assets, tools, etc. However, if these sections are not suitable, the SEMIC email address can be used to make inquiries ([email protected]).
The SEMIC Support Centre is a centralised place where documentation on SEMIC specifications, their releases, pilots, tooling, blog posts, webinar recordings, events, … and much more SEMIC related content can be found. Visit the SEMIC Support Centre and explore everything SEMIC has to offer.
