EUROPEAN OPEN STANDARD

The European Standard for Workplace Orchestration

Unifying open source workplace apps into a true platform alternative to Microsoft 365

THE PROBLEM

The Workplace Tech Paradox

Europe now has serious open source workplace tools — email, docs, project management, video, chat. They're mature, deployable, and increasingly adopted. Yet dependency on dominant suites keeps growing.

Why? Not because the alternatives are bad — but because Microsoft and Google have something more: the platform effect.

  • It's not "a software" — it's an interlocked ecosystem designed to work as one
  • Leaving feels like a risk, not a project: cost, complexity, habits, continuity
  • SSO across apps isn't enough — a shared login only produces an app catalog, not a platform

What's missing isn't better apps — it's the orchestration layer between them.

The Platform Effect Gap

Open source apps work — individually. But dominant suites win because they feel like one product: shared context, seamless workflows, unified experience. Individual excellence doesn't beat ecosystem cohesion.

SSO Is Not a Platform

A single login across multiple tools sounds like progress — but it only produces an app catalog behind one door. What's missing is the orchestration layer: identity, rights, notifications, documents and workflows circulating between services.

Strategic Dependency

The lock-in isn't just budgetary — it's political. Roadmaps, integrations, and platform orientations are decided outside Europe, durably structuring organizations that have no seat at the table. Sovereignty requires infrastructure, not just intentions.

THE VISION

From Fragmentation to Unity

Open Buro orchestrates existing apps into a cohesive platform—no vendor lock-in, no rip-and-replace.

Universal Packaging

Standard app format. One registry. Any publisher can contribute.

Shared Navigation

Common home, unified app grid, global search. Users never lost.

Cross-App Data

Business objects flow between apps. Semantic graph connects knowledge.

Collective Identity

Organization-wide groups, permissions, presence. Manage once, apply everywhere.

Open Buro doesn't replace your apps. It makes them work together.

TWO PILLARS

Standard + Alliance

Technical orchestration meets ecosystem coordination

The Standard

Unified SSO with OIDC flow, standard app packaging format, centralized registry for discovery, common settings API for consistent UX. Publishers integrate once, users authenticate once.

Shared home screen, unified navigation bars, global app grid with search, cross-app command palette, integrated support system. Users navigate the platform, not individual apps.

Business object definitions (contacts, documents, tasks), cross-app event streaming, semantic knowledge graph, unified RAG/search APIs. Data flows between apps with context preserved.

Cross-service workspaces, threaded comments on any object, notification center aggregating all apps, shared presence and status. Collaboration transcends app boundaries.

Capability/intent casting (apps expose functions to platform), unified video conferencing, shared file picker, integrated image editing. Apps compose into workflows, AI agents orchestrate across tools.

Platform-level end-to-end encryption vault, granular permission models, audit logging, secure secret storage. Security is orchestrated, not fragmented across apps.

Flagship mobile app (iOS/Android) with embedded webviews, dedicated native apps for core tools, desktop client (Electron/Tauri), augmented browser extension. One platform, all devices.

The Alliance

A Manifesto

Open Buro exists to prevent European workplace fragmentation. Open source without orchestration creates chaos. We establish founding principles before code.

Open Governance

Neutral foundation structure modeled on Linux Foundation, CNCF. No single vendor controls the standard. Transparent decision-making, public roadmap.

Adoption Actions

Implementation support for publishers: reference architectures, migration guides, certification program. Alliance members don't just endorse—they implement.

International Visibility

European-scale promotion: conferences, government outreach, media relations. Make Open Buro the default assumption for workplace tech procurement.

Funding

Resource mobilization through member contributions, public grants (EU innovation funds), commercial services. Sustainable funding model ensures long-term viability.

"Code is Law... but Architecture is Politics"
