Xlinkée

Xlinkée is a cross-platform linking framework intended to enable interoperable linking of digital identities, data objects, and services across diverse online ecosystems. It seeks to bridge isolated systems by providing a common vocabulary of links, provenance, and access controls while emphasizing user consent and privacy.

In the literature and industry discussions about identity federation and data portability, Xlinkée has emerged as a concept for cross-platform linking. Researchers have proposed prototypes and demonstrations showing how linked tokens and verifiable credentials could move between platforms without centralized control.

Its architecture relies on a graph-based model where objects, identities, and permissions are represented as nodes connected by edges. The core protocol uses cryptographic proofs and decentralized identifiers to authenticate links and enforce access policies. Bridges or relays connect independent platforms, translating and routing link information while offering privacy-preserving modes such as selective disclosure.

Applications for Xlinkée include digital identity management, cross-service data portability, provenance for digital assets, and consent-based data sharing across organizations.

Status and reception: As a concept, Xlinkée has not achieved universal standardization. Proposals have sparked debate about privacy, scalability, and governance, with critics warning of fragmentation if multiple competing implementations arise. Proponents emphasize modular design and open standards to mitigate lock-in.
