2. 2
• The EU Regulation 2017/1926
• Requirements
• Status
• Challenges & Opportunities for the Semantic Web Community
• Impact on Transport Stakeholders
• Our Ongoing and Future Work
Agenda
3. 3
EU Regulation 2017/19261: Requirements
• Each EU Member State is required to set up a National Access Point (NAP)
• allowing access to static data (e.g., timetables, network topology, list of services offered at a
station / airport) and dynamic data (e.g., delays, cancellations) related to different transport
modes (air, train, bus, ferry, metro, tram, car/bike-sharing, car-pooling, etc.)
• defined according to specific standard data formats such as NeTEx CEN / TS 16614 and
SIRI CEN / TS 15531
• described using national application profiles (e.g., DCAT-AP)

4. 4
EU Regulation 2017/1926: Status
• The first deadline for the provisioning of the first set of static transport data through NAPs is
December 1st, 2019
• According to [1], very few transport stakeholders are ready to provide their data and services
in compliance with the standards requested by the EU Regulation
• To enable a data conversion process, they rely on their in-house support (which may lack
knowledge and skills related to the Regulation) or turn to external technology providers that
provide custom and often expensive solutions

5. 5
• Reference ontologies
• unambiguously describe the operational aspects of the transport domain
• Metadata profiles for transport datasets
• harmonize the metadata description of datasets through a semantically-enhanced metadata profile
• Semantic Web-based transport data converters
• turn available transport data into specific data formats and, in case, enrich them with additional data sources
• e.g., a specific (semantic) converter enables the translation of transportation schedule, geographic and fare
information expressed in GTFS to a NeTEx specification preserving the original meaning

6. 6
EU Regulation 2017/1926: Impact on Transport Stakeholders (1)
Obligations
• Establish the NAP and defining its governance framework
• Define a national profile for metadata description of the datasets
NAP
Management Board
Challenge
• Regroup the existing public and private access points in a single
point, solving interoperability and compliance issues and avoiding
dataset duplication
Benefit
• Potential commercial aspects for data sharing, brokerage, and trading
7. 7
EU Regulation 2017/1926: Impact on Transport Stakeholders (2)
Obligations
• Provide datasets to the NAP compliant to the requested data formats
• Provide metadata description of the datasets
Challenge
• Turn available data into the requested data formats and, in case,
enrich them with additional data sources
Benefit
• Enhance the knowledge and the adoption of their transport offerings
• Potential revenues from data trading
Transport Authorities
and Operators
Transport
Infrastructure Managers
8. 8
EU Regulation 2017/1926: Impact on Transport Stakeholders (3)
Obligation
• Notify the NAP Management Board on the release of new versions of
data formats/standards requested by the EU Regulation
Challenge
• Provide a reference vocabulary for the transportation sector
Benefit
• Improve and enhance the adoption of developed standards
Standardization
Bodies
9. 9
EU Regulation 2017/1926: Impact on Transport Stakeholders (4)
Obligation
• Follow terms and conditions established by the NAP Management
Board concerning the NAP data usage
Challenge
• Use the NAPs for ITS app development and for the identification of
new mobility service offerings to be integrated into MaaS solution.
Benefit
• Interoperable data on multimodal transportation are available to be
elaborated for providing innovative services to users/travelers
ITS and MaaS
Providers
10. Conceptualization
• Acquire knowledge of the
domain
• Acquire knowledge of
data formats/standards
• Define the reference
ontology
Sharing
• Define asset types
• Define asset descriptors
Governance
• Identify actors, roles and
associated tasks
• Define of the lifecycle of
each asset type
• Define processes to
automate the lifecycle
management
Conversion
• Define models and rules
to enable the
conversion process
Ongoing & Future Work
11. 11
• A reference ontology for the transport domain derived from a sub-part of the CEN
Transmodel1
• The ontology will represent a starting point for a potential collaboration with the CEN TC278-
WG3-SG4 that has formally defined the Transmodel
• A new RML-based solution to turn transport data into EU Compliance
• More details? My talk at SEMANTiCS 2019!
• Session 3.5 “LegalTech”: Tuesday, September 10, 2019 – 16:00 to 17:30
Ongoing & Future Work

12. 12
• Semantic catalogue of distributed digital assets (i.e., datasets, APIs, ontologies)
enhanced by tools for their governance, publication, and discovery
• Process-based asset lifecycle management
• DCAT-AP metadata management (asset description)
• Value-added services (e.g., semantic search of assets)
• MaaS scenarios and demonstrations
• Test of Shift2Rail IP4 projects results as enabling components for MaaS solutions
