- The Data Space Trust List is an official and voluntary register that identifies trusted data sharing environments in Spain.
- The system is based on the UNE 0087:2025 specification, the first common national framework for the creation and operation of data spaces.
- The registry publishes basic information about each space (website, contact, promoter and description) to provide transparency and security.
- The List is coordinated with the aid provided by the Data Spaces Kit program, which has a budget of 500 million euros and is managed through Red.es.

The Ministry for Digital Transformation and Public Administration has launched the Data Space Trust ListA new official registry aims to bring greater security and order to data sharing in Spain. This measure is designed to help companies, government agencies, and other entities more clearly identify which initiatives meet common minimum requirements.
With this tool, the Government intends Strengthening confidence in the data economy and to enable organizations to make decisions with less uncertainty when participating in data spaces. The registry is intended to become a reference for easily identifying which projects have undergone a technical and security evaluation process overseen by the Administration.
What is the Data Space Trust List
The Trust List is, in essence, a official registration and voluntary membership Managed by the State Secretariat for Digitalization and Artificial Intelligence, it includes data spaces that demonstrate compliance with the technical, security, and governance criteria defined by the Ministry for Digital Transformation and Public Administration.
This record falls within the Data Space Development PlanThe state strategy aims to consolidate a robust information-sharing ecosystem across various economic and social sectors. This initiative is conceived as one component of a broader policy designed to ensure that data is used securely, interoperably, and with guarantees for all parties involved.
As it is a voluntary system, entities promoting a data space decide whether they want to undergo this recognition process. In return, inclusion on the list acts as a confidence indicator before potential participants and partners, since it implies having passed an evaluation aligned with specific regulations and standards.
The Ministry's stated objective is to provide the market with a clear and recognizable frame that makes it easier to distinguish which spaces have an adequate level of technical maturity, security and governance, key aspects for data sharing to be done with certain guarantees.
The Trust List is also interpreted as a tool to promote a Spanish data space ecosystem aligned with European initiatives, where the creation of common sectoral spaces is one of the major priorities for the coming years.

Legal basis and criteria: Order TDF/1207/2025
The operation of this registry is regulated by the Order TDF/1207/2025, of October 27This document establishes both the evaluation criteria and the procedure for registering each data space. It specifies what is required of applicants and how it is determined whether a data space can be considered reliable.
Among other aspects, the order details what information will be public Once a data space is added to the list, its information is included in that publicly accessible record. This information includes, for example, the website, basic contact details, a brief description of the space, and the name of the promoting entity responsible for it.
The design of the standard seeks to ensure that the evaluation is based on a homogeneous technical frameworkThis avoids disparate interpretations or different requirements depending on the type of entity. In this way, all spaces seeking to join are examined by the same standards, which contributes to greater legal and operational certainty. cyberattack on administrative records.
Order TDF/1207/2025 also establishes the administrative steps to follow to request registration, the processing times and the possible causes of refusal or review, which provides a clear and predictable procedure for interested organizations.
This regulatory framework positions the Trusted List as a official reference tool This is beneficial for both the public and private sectors, as anyone can check which initiatives have been formally recognized by the Administration.
UNE 0087:2025, the standard that supports the model
One of the technical pillars of this initiative is the specification UNE 0087: 2025, developed by the Spanish Association for Standardization (UNE). This normative reference is considered the first common framework in Spain for the creation and operation of data spaces, and serves as a direct basis for the record's evaluation criteria.
This specification defines key elements such as the interoperability between systems, data governance models, access control mechanisms, or the minimum guarantees of security and quality of the information shared in these environments.
The use of UNE 0087:2025 allows the Trusted List requirements to be anchored in a agreed technical standard with stakeholders in the sector, and not solely based on internal government criteria. This helps data spaces grow and connect with other ecosystems, both in Spain and at a European level.
Adopting a common framework is especially relevant at a time when the deployment of European data spaces in strategic areas such as health, energy, mobility, or industry. Having a clear national reference point makes it easier for Spanish projects to align with EU initiatives.
In practice, the Trust List acts as a “administrative seal” linked to UNE 0087:2025, which certifies that the data space has reached a certain level of maturity according to these technical and organizational parameters.

Public information and transparency of the registry
One of the elements that the Ministry wanted to highlight is the component of transparency associated with the Trusted List. Once a data space is registered, certain information becomes publicly available to any interested person or entity.
Among the data included in that public section are the website address The data space includes basic contact information and a brief descriptive overview, as well as identification of the entity promoting the project. This visibility makes it easier to know who is behind each initiative.
From the perspective of organizations that value participating in a data space, this public sheet offers a first quick photograph which helps to identify what type of environment it is, what actors are involved and how communication can be established with those in charge.
The Administration emphasizes that this open approach aims to reduce the opacity surrounding data sharing projectsThis has sometimes been a barrier to other entities wanting to collaborate and to avoid risks such as a cybersecurity alert.
At the same time, being on the list can become a differentiating element for data spaces seeking to attract new participants or demonstrate a recognizable level of compliance to partners, investors, or public administrations.
How to apply for inclusion on the Trusted List
Promoting entities that wish to have their data space recognized in this registry must process the application through the Data Space Reference Center (CRED)This portal provides the necessary forms and supporting documentation to complete the process.
According to the Ministry, applications can be submitted without time limitIn other words, there is no fixed application period, but rather an ongoing open process. This allows projects at different stages of development to apply when they believe they meet the requirements.
The CRED centralizes both the electronic submission of documentation such as access to applicable regulations, guides and other resources that help to interpret the UNE 0087:2025 specification and the associated evaluation criteria.
Once the application is submitted, the data space undergoes verification to ensure it meets the technical and security filters stipulated by the Ministry. Depending on the result of this evaluation, is approved or denied inclusion in the list, with the corresponding notification to the promoting entity.
This scheme aims to make the process structured but flexibleso that both established projects and expanding initiatives can be added when they reach the required level of maturity.

Relationship with the Kit Espacios de Datos aid program
The creation of the Trusted List is closely linked to Data Spaces Kit aid program, also promoted by the Ministry for Digital Transformation and Public Administration within the same strategic framework.
The Data Spaces Kit is a financial instrument designed for to provide financial support to the entities who want to join data centers or deploy these types of environments. Applications for assistance can be submitted through the electronic office of Red.es to the 31 March, as the Administration itself has pointed out.
Both initiatives have been designed to work in a coordinated manner: the Kit provides the resources necessary for the deployment and participation of entities, while the Trusted List establishes the framework which defines what is considered a trusted data space in technical and security terms.
The Ministry emphasizes that the existence of the registry allows expand the number of eligible data spaces for these grants, since it offers a clear mechanism to identify projects that fit the model that is to be promoted through public policy.
Taken together, the combination of direct funding through the Kit and official recognition through the list aims to generate a lever effect that accelerates the creation and consolidation of data spaces in different sectors.
A pillar of the Sectoral Data Spaces Promotion Plan
The Trusted List and the Data Spaces Kit are part of the Plan to Promote Sectoral Data Spaces, a strategic program with a global endowment of 500 millones de eurosThis plan aims to boost the data economy in Spain through specific projects in various fields.
The underlying idea is that by fostering safe and clearly regulated environments for sharing information, it will be possible to generate new services, improve processes and to facilitate innovation in both the public and private sectors.
In this context, the Trusted List functions as a structural element that contributes security, order and homogeneity to the ecosystem, while other instruments of the plan are responsible for boosting investment and the deployment of use cases.
The Ministry links this strategy to the broader objective of Spain having a robust data infrastructurecapable of connecting with future European networks and harnessing the economic and social potential of information exchange.
Strengthening trust, regulatory clarity, and the existence of economic incentives are considered basic ingredients so that organizations lose their fear of sharing data and see these initiatives as a real opportunity for growth.

With the implementation of the Data Space Trust List, Spain incorporates a formal mechanism for identifying reliable projects This information-sharing initiative, supported by a national standard (UNE 0087:2025) and linked to a robust support program such as the Data Spaces Kit, is a voluntary but benchmark registry that complements the tools of the Sectoral Data Spaces Promotion Plan. This plan aims to consolidate a more mature, transparent data economy aligned with European priorities.
