Methodological approach and Roadmap

2.
This project has received funding from the Digital Europe Programme under grant agreement n°101083655.
Task 3.4 Objectives
• Subtask 3.4.1
• Identify governance frameworks, reference architectures, etc. eligible for analysis​
• Analyze the governance frameworks, business models and other strategies for
proposed BBs​
• Analyze the identified data sharing ecosystems for inherent, sector specific BBs
• Subtask 3.4.2
• Work on the proposal of common mobility-specific building blocks and requirements
using the specifications elaborated by Task 3.4.1​
• Suggest incentive schemes to motivate participants to provide data​
• Identify legal avenues to foster data reuse in mobility, such as the revision of legacy
legal frameworks​
• Contribute to a graphical representation of the project’s findings​

Methodology for Analysis of Building Blocks
TOP-DOWN MEETS BOTTOM-UP: REFERENCE ARCHITECTURES MEET BEST PRACTISE
Define the Data Space Capabilities
analysing Theoretical Architecture and
Building Blocks Models
BOTTOM-UP-FIRST-APPROACH:
• ANALYZE EXISTING (THEORETICAL) MODELS
• EXTRACT PROPOSED BUILDING BLOCKS
• TRANSLATE/MAP ALTERNATIVE CONCEPTS
• CONSOLIDATE CONTENT
• PROVIDES COMMON DS FEATURES
• ALLOWS FOR COMPREHENSIVE PICTURE
• ENRICH LATER WITH BEST PRACTICES
REPRESENTATIVE GUIDELINE FOR THE
IMPLEMENTATION OF DATA SPACES
BOTH A TOP-DOWN AND BOTTOM-UP APPROACH HAVE THEIR LIMITATIONS
RISKS AND OBSTACLES:
• SEVERAL DIFFERENT MODELS NEED TO BE ANALYZED
• MAPPING MIGHT BE DIFFICULT
• CONSOLIDATION INTO ONE FINAL MODEL WILL BE TIME CONSUMING
• PROBABLY POOR INPUT REGARDING BUSINESS MODELS AND INCENTIVES
• WORK SUPPOSED TO BE DONE BY DSSC
Identify Building Block Requirements by
investigating existing Best Practises from
representative Use Cases

METHODOLOGY FOR ANALYSIS OF BUILDING BLOCKS
TOP-DOWN MEETS BOTTOM-UP: REFERENCE ARCHITECTURES MEET BEST PRACTISE
Identify Building Block Requirements by
investigating existing Best Practises from
representative Use Cases
Define the Data Space Capabilities
analysing Theoretical Architecture and
Building Blocks Models
TOP-DOWN-FIRST-APPROACH:
• Analyze Existing Data Space initiatives
• Assess Each Architecture Model/Building Block “Usage”
• Business Models and incentives from Reality
• Weaknesses and strengths Experience
• Consolidate findings
• Enrich later from standard models
• Allows for pragmatic picture of the feasible
• Sector and Use Case specific features
• Needs anyway an idea of possible Building blocks
REPRESENTATIVE GUIDELINE FOR THE
IMPLEMENTATION OF DATA SPACES
BOTH A TOP-DOWN AND BOTTOM-UP APPROACH HAVE THEIR LIMITATIONS
RISKS AND OBSTACLES:
• Small number of sufficiently advanced projects
• Poor responses to the surveys
• Not all BBs considered
• Great variety of information formats

5.
This project has received funding from the Digital Europe Programme under grant agreement n°101083655.
Methodology for Analysis of Building Blocks - A Best Practices Approach:
1. Survey within all members of the inventory on:
• Data sharing architecture, Building Block usage, Governance Processes, Business Models, based on
the OpenDEI BB Schema, plus attractors, showstoppers
2. Generation of a refined view on data space design with selected DS:
• Survey on the implementation of capabilities in detail (enriched OpenDEI capabilities catalogue)
• Reasons for absence of capabilities
• Adherence to legal constraints
3. Validate with representative Use Cases

This project has received funding from the Digital Europe Programme under grant agreement n°101083655.
• Questionnaire I addressing the needs for both T3.3 and T3.4
• Addressing the required inputs for both T3.3 and T3.4:
• Addressing cornerstones of data usage
• Asking for technical and organisational Building Blocks
• As refinement for each of the (extensive set of) contributions / entries in the WP2 Inventory
1. What type of data sharing is supported?:
a. Sharing of persistent (semi-static) data
b. Sharing of (real-time) streaming data
c. Algorithm sharing for local processing of (sensitive) data
d. Smart contracting for data flow control
e. Multiple of the above
f. None of the above
Additional Remarks (open question)
1. Do you (plan to) adopt a building block implementation according to
an EU Reference Architecture Initiatives
a. Building blocks from the IDSA Reference Architecture?
b. Building blocks from the GAIA-X Reference Architecture?
c. Building blocks from the ISHARE Reference Architecture?
d. Building blocks from the SIMPL Reference Architecture?
e. Building blocks from the FEDeRATED Reference Architecture?
f. Building blocks from another Reference Architecture?
g. Mix of elements from different Reference Models
Additional Open Questions:
∙ What building blocks of these EU Reference Architectures do you use or
plan to use?
∙ What is the motivation for using the building blocks from the selected EU
Reference Architecture(s)?
• Example (in development)

DATA NEEDS (TOP-DOWN)

7.
This project has received funding from the Digital Europe Programme under grant agreement n°101083655.
• Interviewing selected stakeholders for technical and organisational best practises
• Based on a more detailed questionnaire II
Metadata and Discovery Protocol Are all actors/elements in the DSP described?
Which description formats are used?
Were domain-specific descriptions (elements) applicable?
Which technologies are implemented for the handling of the description?
Which parts of the implementation reside in the connector/on party-side, which in a federated soft infrastructure?
Data Usage Accounting Are the events triggered by actors logged, counted, compiled for the use in clearing, payment, and billing procedures?
Which parts of the implementation resides in the connector/on party-side, which in a federated soft infrastructure?
Publication and Marketplace Services How is the body of data descriptions made public?
Which catalogue technology is used?
How is the catalogue linked to other functions of the soft infrastructure (smart contracting, monitoring/accounting)?

METHODOLOGY FOR ANALYSIS OF BUILDING BLOCKS
OUTCOME OF THE ANALYSIS
Discover key insights that will result from this analysis and in-depth expert interviews to help support the framework
towards a European Mobility Data Space:
Outcome #1 – quantitative
• List of commonly considered Building Blocks/Capabilities
• List of sector specific Building Blocks
• List of example Use Cases of the sector (already implemented, or under work)
Outcome #2 – qualitative
• Understanding of common interpretation of necessary data space characteristics (technical and organizational)
• Identified enablers for data sharing; e.g. attractive business models, innovation opportunities, efficiency
• Common access barriers preventing potential players to enter data space ecosystems
