Catalog

Contract Negotiation

Transfer Process

What happens?

A public transportation authority
decides to share its transit schedules
with app developers.

An app developer wants to use
these schedules to create a route
planning application.

Once the agreement is in place, theactual data transfer begins.

Problem

Inconsistent data formats forschedules across different
platforms.

Need for clear terms regarding
the use and distribution of thetransit data.

Ensuring secure, efficient, andreliable transfer of transit data.

Role of DSP

Standardizes the format for
publishing transit schedules.

Facilitates agreement on data
usage terms and conditions.

Manages the secure and efficienttransfer of the agreed-upon data.

Specification
ExampleData provider publishes schedules
using ‘DCAT Catalogs’ and sets
access rules with ‘ODRL Policies’.

Developer and authority
negotiate using ‘Contract Offer’messages, leading to a ‘Contract
Agreement’.

Data transfer is executed through‘Connector-to-Connector
Communication’ and ‘Data
Transfer Requests’.

Facilitating interoperable data sharing−

Goal: provide a blueprint for data spaces in Europe that comprises
common building blocks for business, legal, operational, technical, andsocietal aspects.

−

coordinate on behalf of the European Commission all relevant actions on
sectoral data spaces in Europe−

support the establishment of common data spaces in Europe by making
technologies and standards widely available across sectors− Coordination and support action funded by the European
Commission under the Digital Europe Programme−Multidisciplinary consortium of 12 leading associations and knowledge

Avoiding confusion

The term transaction and more specifically “Data Transaction” is used broadly in the DSSC Blueprint and invarious other contexts. It is used heavily in the current European legislation, e.g., Data Act. Given the fact,that the current DSSC Blueprint is dealing with legal definitions, business related aspects and technicalaspects, it should be considered, that the term “transaction” has different meaning and understanding insuch domains.
Business:

Legal:

Computing:- Definition: In the business context, atransaction refers to an exchange orinteraction between two or more parties
involving the transfer of goods, services,or money.

- Definition: In legal terms, a transaction
is a specific act or series of acts
conducted according to legal rules andregulations.

- Definition: In computing, a transactionrefers to a sequence of one or more
operations that are executed as a single unit,
ensuring consistency and integrity of data.

- Key Elements: Legal transactions may
include contracts, agreements, or otherlegally binding actions. They often
require the presence of certain legal
elements like offer, acceptance, andconsideration.

- Key Elements: In database management
systems, for example, transactions are used
to maintain the integrity of data by ensuringthat all operations within the transaction arecompleted successfully or none are executedat all (atomicity). Transactions also adhere to
the principles of consistency, isolation, anddurability (ACID properties).

- Key Elements: Transactions typicallyinvolve an agreement between parties,
consideration (payment or value
exchange), and the intention to create
legal relations.

Trusted Data Transactions
A proposal for definition

The process of an interaction between two participants with the purpose of creating a lawful and contractual basis for data sharing,
publication, discovery, sharing, accessing, exchanging, and processing data.
Explanatory text:

A data transaction implies data sharing among involved participants and its usage on a lawful and contractual basis. It relates to thetechnical, financial, legal, and organizational arrangements necessary to make a data set from Participant A available to Participant B.
The physical data transfer may or may not happen at the time of the data transaction.
Key elements of a data transaction are•

The Data Holder grants rights to a data provider.

•

The Data Product is published by the Data Provider, including the option to publish them to a third-party service provider.

•

Discovery of Data Products by a potential data consumer / data user•

Negotiation of a contract including technical policies between data user / data consumer and the data provider•

Data exchange or data sharing, i.e., Data Transfer, between the parties, including optional transaction participants, like observers.

•

Data access and data usage on the consumer/ user side•

acknowledging that not all activities need to be conducted in every transaction and that parts of the activities may be visited inloops or conditional flows.
