Tool Information

Name: mobilityDCAT-AP Generator Tool

Description:
A form-based web interface that generates RDF metadata according to the mobilityDCAT-AP specification. This tool allows users to create structured, machine-readable metadata descriptions for mobility datasets and data services without needing to write RDF code directly. It's designed to help data publishers test and experiment with different metadata elements while learning how to properly describe mobility data according to the mobilityDCAT-AP standard. The form is compliant with the minimum profile of mobilityDCAT-AP.

2. Standardization: Ensures metadata follows the recommended European standard
3. Educational value: Helps users understand mobilityDCAT-AP requirements through hands-on experience
4. NAP adoption: Supports implementation of mobilityDCAT-AP across National Access Points
5. European initiative: Part of official NAPCORE recommendations for metadata harmonization
6. Quick start: Enables data publishers to create compliant metadata immediately
7. Open approach: Transparent, community-driven tool development
8. Cross-border interoperability: Facilitates findability and reusability of mobility data across Europe

About mobilityDCAT-AP

mobilityDCAT-AP is a metadata specification developed by NAPCORE to enhance cross-border and cross-sectorial discoverability of mobility-related datasets. It extends DCAT-AP (the European standard for data portal metadata) with mobility-specific elements, providing precise metadata designations for data topics, providers, formats, geographical coverage, and other mobility-relevant aspects.

The specification addresses the fragmented European mobility data ecosystem by enabling harmonized, platform-independent metadata descriptions in both human-readable and machine-readable formats. It's recommended for use in National Access Points and other mobility data portals across Europe.

Key mobilityDCAT-AP Resources:

• Specification v1.1.0: Released January 2025
• Governance: Maintained by NAPCORE Metadata Working Group
• Requirements: Based on 40 requirements from literature review and stakeholder input
• Adoption: Early adopters include several European NAPs
• Documentation: Comprehensive specification, wiki, and accompanying guidelines
