MIM3: Exchanging Data

Introduction

This MIM helps cities and communities set up a local data ecosystem that is globally interoperable. It helps overcome the challenges of how data can be “pooled together” across diverse systems of different organisations into a common data space that enables data providers and users to exchange data in a trusted way with confidence and derive value from it.

Use Cases

Objectives

  1. To enable the setting up and management of effective and trustworthy data-sharing ecosystems, ensuring that provided data sources can be discovered by data users and made available under asserted terms of the data providers.

  2. To ensure that data-sharing ecosystems that comply with this MIM have a basic level of interoperability with each other and are based on clear governance rules that are transparent to all participants.

Capabilities and Requirements

Capability C1: Clear governance rules for a data-sharing ecosystem that are transparent to all potential data eco-system participants and easy to understand.

C1 Requirements:

R1: A data ecosystem should define a governance model that outlines membership rules, the roles, responsibilities and obligation of members /participants and principles that govern the data exchange beween them.

R2: Members who participate in a data ecosystem should be made aware of its governance model or any changes made to it.

R3: The governance model should be easily comprehensible by all ecosystem participants.

Capability C2: Data providers are empowered to define terms and conditions for sharing data in a way that they are easy to understand for data users (data sovereignty).

C2 Requirements:

R4: Data providers are free to define terms and conditions under which they want their data to be exchanged in accordance with the overall governance model of the data ecosystem. (Note: A data provider can decide to not participate in a data ecosystem if the underlying governance model is too restrictive.)

R5: Terms and conditions for a data exchange should be described clearly and unambiguously so that they are easily understandable for data users. (well structured meta-data, model licenses/contracts etc.

R6: Data a providers should be able to contain trusted information about data users who want to access their data sources before granting access to their data. (see meta-data about participants).

Capability C3: Data users can discover what data sources are available and who the providers are.

C3 requirements:

R7: Data users should be able to discover what data is available to them without prior knowledge of the data ecosystem. (see meta-data about data sources)

R8: Data ecosystem participants should be able to obtain trusted information about data providers and their data offerings relevant for data exchange (see meta-data about participants).

Capability C4: Compliance by both data users and providers with terms and conditions for data sharing (use and supply) can be validated.

C4 requirements:

R9: Data ecosystem participants must be reliably identified before establishing a data exchange.

R10: A data ecosystem must be able to ascertain compliance of its participants to the government model of the data ecosystem.

R11: Data exchange can only takes place when data provider terms are met both by data users and data providers.

Capability C5: Meta-data is provided to ensure that data users have sufficient data available about data sources to make informed decisions to engage in data exchange (meta-data about data sources)

C5 requirements:

R12: Data sources offered by a data provider should be clearly described with adequate meta-data so that a data user understands their nature before initiating a data exchange.

Capability C6: Meta-data is provided to ensure that data providers and data users have sufficient information about each other to make informed decisions to engage in data exchange (meta-data about participants)

C6 requirements:

R13: Each ecosystem participants should be clearly described in a data sharing ecosystem so that others can ascertain their indentity and reputation.
