SOVEREIGNTY
NO LOCK-IN, IN WRITING
yOUR DATA, YOUR MODELS, AND YOUR HISTORY BELONG TO YOU. YOU EXPORT THEM ON ANY DAY, IN OPEN FORMATS, AT NO COST. LEAVING VELA IS FREE.

We build on the ETSI NGSI-LD standard and publish our tools as open source, so the exit is not a promise. You verify each part of this page yourself, starting with the repositories below.
WHAT YOU OWN
Every Vela contract includes the export clause and an IP annex listing who owns each deliverable.
YOU HOLD:
- Every entity, exportable as NGSI-LD (JSON-LD)
- Your full history, exportable as Parquet or CSV
- Your context files and data models (Smart Data Models, public by definition)
- Your open-data catalogue (DCAT-AP)
- An NGSI-LD context broker of your choice: Scorpio, Orion, Orion-LD, or Stellio, all open-source projects anyone installs
- Everything we built specifically for you: scripts, flows, dashboards, and applications, each marked as yours in the IP annex
The export clause works on any day, not only at termination. Test the export in month one. We encourage this.
SCOPE
This page describes the Vela Context Data Hub platform. Vela Cloud Services (Vela Pulse, Vela Tide, Vela Transit, Vela Care, and others) are subscriptions: every report and data export you pull from them during the term is yours to keep, the services themselves stay in the cloud.
OPEN-SOURCE EDITIONS
Vela tools ship in two editions. The FOSS edition carries the core function under EUPL 1.2, free forever. The Pro edition adds clustering, SSO, audit trails, multi-tenancy, and premium connectors. Each repository README carries the exact feature matrix. A released FOSS feature never moves to Pro. Vela Tools.
FOUR WAYS TO RUN VELA context data hub
You choose how much independence you want, on day one or later. You move between these models in either direction, whenever your strategy changes.
1.
MANAGED PLATFORM
We run everything on SandBoxOS, our operations layer. You get a product, not a project.
2.
HYBRID
Your infrastructure, our Pro tools, our SLA. Your team holds the keys, we hold the pager.
3.
SOVEREIGN FOSS
Your servers, FOSS editions, your jurisdiction, your team. Support contracts optional.
4.
INDEPENDENT
Everything in-house. We remain available for custom development on demand.
AN HONEST LIST
Moving between models takes work, and you deserve the full picture before you start, not after.
WHAT MOVES WITH YOU
- Everything in "What you own" above
- The custom work we delivered for you: scripts, Node-RED flows, Grafana dashboards, and applications marked as yours in the IP annex
- The FOSS editions of the Vela tools and their public documentation
WHAT YOU SET UP ON THE NEW TARGET
- Ingestion mappings from your sources
- Gateway access policies
- Replacements for the Vela platform library: reusable flows, script templates, and default dashboards, which stay with the platform
- The wiring between broker and archive
- Day-two operations: updates, monitoring, backups, on-call

The IP annex in your contract lists every deliverable under one of these tags, so nothing on this page is a surprise at the end. Request the sample IP annex →
Your team handles the setup with the public documentation. Many teams do.
WE DO THE MOVE FOR YOU (OPTIONAL)
If you would rather not carry the boxes yourself, we offer the migration as a fixed-scope service: server build on your infrastructure, broker and data migration verified against export checksums, FOSS edition installation, a handover runbook, and optional training for your team.
Fixed scope, fixed quote, available on request at any point, including before you sign anything. Entirely optional. The do-it-yourself path above costs nothing.
FOR PROCUREMENT
REVERSIBILITY, ON THE RECORD
EU public-sector frameworks require exit and reversibility clauses. GIBIT (NL) and EVB-IT (DE) both score reversibility in evaluation. This page is our standing answer, and every claim on this page appears in the contract, including the IP annex with per-deliverable ownership.
Feel free to attach this page to your evaluation file.
