For Client Organisations
Licensing Overview
Juno Cassandra licences are purchased and held by the infrastructure-owning organisation — for example a town council, toll agency, or national government agency. The commercial relationship is between Lonrix Ltd and that organisation.
Please contact Lonrix for a quotation. A licence is quoted for your organisation based on the size of the network you intend to model and how you intend to use the software.
What Your Organisation Needs to Provide
Very little. Juno Cassandra runs in a web browser, so there is no software for your IT department to install, approve or maintain, and no per-machine setup for the people who use it.
What we do need from you is the list of people who should have access, and what each of them should be able to do.
How Analysts Use Your Licence
A modelling analyst — your own staff member or an external consultant — must be formally nominated by your organisation before we give them access to your project.
How many people you authorise, and at what access level, is agreed with us when the licence is set up and can be revisited as your needs change. It may affect the licence cost, so it is worth telling us early what you have in mind.
Each person gets their own account, secured with a password and two-factor authentication. Accounts are never shared between people, which is what makes the audit record meaningful.
Two Levels of Access
When you nominate someone, tell us which of these they should have:
| Access level | Can do |
|---|---|
| Modeller | Upload and change input files, tune the setup, run models, publish results |
| Stakeholder | View the project and its results — read-only. Cannot change files or start a run |
Stakeholder access is worth using. It lets asset managers, engineers and executives see forecasts and budget scenarios as they are produced, without any risk of a setup being changed by someone who did not intend to.
Adding and Removing People
Notify Lonrix of the change and we will action it. Adding people beyond what was agreed may affect your licence, so ask us first if you are unsure. Removing someone’s access is immediate and complete — because access lives on our servers rather than on their machine, there is no copy of the software or of your data left behind on a laptop when a consultant’s engagement ends.
Licence Limits
Each licence includes a limit on the number of elements in the network model. This may mean:
- Road segments (for road networks)
- Pipe elements (for water networks)
- Structural elements such as trusses or piers (for bridge networks)
The limit is checked when a model run starts. If an input set exceeds it, the run does not proceed.
Your Own Domain Model
Your licence includes the right to build and publish your own domain model — the engineering logic behind the forecasts, as distinct from the software that runs it. If your network, your treatments or your deterioration behaviour differ from the standard model, one of your engineers can own that logic rather than asking us to change it for you.
The tooling that makes this practical is free and public. See Training for how we help people get there.
Protection Against Misuse
To protect your licence, Lonrix:
- Requires each user to sign in individually, with two-factor authentication
- Ensures input sets stay within your licensed element limits
- Records usage — sign-ins, the client worked under, and runs performed
- Audits licence use, randomly or when anomalies are detected
- May confirm with your organisation that nominated analysts are legitimately working for you
These protections safeguard both licence holders and honest analysts.
