Ontology Specification Draft

Introduction back to ToC

AICat extends DCAT version 3, since this version of DCAT supports cataloguing other resources, other than datasets. Through extending DCAT, AICat aims to scale the cataloguing to AI systems and models to address the needs of the EU database.
AICat profile requirements specification
AICat Requirements Specification Document
1. Purpose
The purpose of AICat profile is to use DCAT and AIRO for describing catalogues of AI systems and their associated components, such as datasets and AI models.
2. Scope
The scope of this AICat is limited to the atomic information that should be submitted upon the registration of high-risk AI systems into the EU database, outlined in Annex VIII. This means that descriptive information, for instance the system's logic and findings of the fundamental rights impact assessment, are not included in the scope.
3. Implementation Language
OWL, DCAT
4. Key Uses
USE 1. Maintaining and managing metadata about AI systems and models in interoperable and standardised catalogues.
USE 2. Discovering and comparing AI solutions.
USE 3. Cataloguing and sharing information about AI systems with the public in a transparent manner, this includes the use by the European Commission for sharing metadata of the high-risk AI system indexed in the EU dataset.
5. Ontology Requirements
a. Non-Functional Requirements
NFR 1. The profile shall be published online with standard documentation.
NFR 2. The profile shall reuse concepts and relations from AIRO to the fullest extent possible.
b. Functional Requirements: Groups of Competency Questions
CQG1. AI systems CQG2. Datasets CQG3. AI model
CQ1-1. What is the name of the system?
CQ1-2. Who is the system's provider?
CQ1-3. Who is the system's deployer?
CQ1-4. What is the system's intended purpose?
CQ1-5. What is the market availability status of the system?
CQ1-6. In which countries is the system made available?
CQ1-7. What is the additional references to the system? 		CQ2-1. Which datasets are used by the system?
CQ2-2. What is the system's input data?
CQ2-3. What is the dataset's use policy? 		CQ3-1. Which models used by the system?
CQ3-2. What is the model's release date?
CQ3-3. What is the model's input data?
CQ3-4. What is the model's output data?
CQ3-5. What is the model's licence?
CQ3-6. What is the model's use policy?
