HRxx

HRxx is a hypothetical open standard intended to enable interoperability among human resources information systems (HRIS), payroll, benefits administration, and related HR applications. It aims to provide a modular data model, consistent APIs, and privacy-conscious workflows to reduce data silos and integration effort.

Origin and scope. The term HRxx originated in industry discussions and educational material to illustrate data interoperability in HR tech. It is not tied to a single vendor or product, but describes a set of conventions for data schemas, API design, and governance.

Core components. The HRxx specification envisions a core data model covering employee identity, employment status, compensation, benefits, training, performance, and time management. It supports JSON and XML representations, versioning, and an event-driven API set for CRUD operations and workflows.

Architecture and data governance. Key elements include a modular core, an API gateway, a security and consent layer, a data mapping port for system compatibility, and a policy framework for consent, retention, and role-based access control.

Implementation and impact. In practice, organizations explore HRxx-compatible interfaces or adapters rather than a sole software package. Pilot efforts focus on cross-system employee records and payroll data exchange, aiming to reduce manual reconciliation and improve data accuracy.

Reception. Supporters cite improved portability and vendor neutrality, while critics warn of complexity and the need for ongoing governance to maintain interoperability and privacy compliance.
