This document summarizes key EU data access regimes including the GDPR, Digital Content Directive, PSD2, and Electricity Directive. It outlines their objectives, intended beneficiaries, and standards for data portability. These regimes aim to promote the internal market, consumer protection, and competition through standardized access to personal and sector-specific data. However, their impact depends on how actively users invoke these rights. The document also references the proposed Digital Markets Act and forthcoming Data Act as developing EU initiatives in this area.
