Data protection information notice for scientific research Project Open Portability

Social networks, particularly Twitter (now X), have from the beginning been privileged objects of research, especially in the field of computational social sciences.

A historic transition is underway in the social network landscape. The centralized model, embodied by X (formerly Twitter), is experiencing a massive exodus of users to alternative platforms like BlueSky and Mastodon. Several million accounts have migrated in just a few weeks, marking a major shift towards decentralized and open networks.

This transition is a major social, economic, and technological phenomenon that may modify the global digital space, particularly in Europe, and could allow Europe to regain some digital sovereignty.

I. Project and Processing Description

The research objectives are as follows: analyze the difference between open and closed micro-blogging digital environments from the perspective of social dynamics and online debates. Study as a case study the ongoing migration between X and spaces based on open protocols AT Protocol and Activity Pub, and study the appropriation of decentralized digital spaces over time (5-year horizon).

The OpenPortability project involves:

Data collection for data portability between social networks
Data collection for creating a snapshot of X network's social structure
Data collection for creating snapshots of alternative networks' social structures
Data portability
Data processing and analysis

II. Data Collection, Recipients, and Retention

Data collected directly from individuals and processed are:

Digital identifiers on social networks (username ID)
Social network profile names
Email addresses
