The European Language Data Space (LDS) is designed as an ecosystem of organisations. Users who own language data and those who want to use language data can perform all actions related to their data assets and interact with other stakeholders within the platform in a secure way and in full compliance with EU laws and regulations.
The main component is the LDS connector. This small piece of software is installed on the users' systems and it enables the participation in the data space as well as the execution of all operations around data exchange, such as the publication, search, negotiation and transfer of data products.

How to get started
To apply for a participation in the LDS, the legal representative (or a delegated person) of an interested organisation fills in the application form and provides the necessary information to verify the eligibility of the organisation.
The LDS Governance Board will assess the application and approve or reject it in compliance with the governance framework.
Once the application is approved, the organisation will receive additional instructions on the technical procedure for accessing the LDS ecosystem and for the installation and configuration of the LDS connector.
Please note that only legal entities established in an EU member state are eligible to participate in the LDS marketplace. The data products to be offered must be under full ownership of (or include clear distribution rights to) the stakeholder who is publishing the offer.
We are happy to help!
The LDS user guide is organised in the form of a walkthrough, describing how to become a member of the LDS marketplace, how to install the required technical components and how to operate the LDS connector.
The LDS legal and technical helpdesks will support users during the testing phase and beyond and provide assistance for any questions or issues.
