Frequently Asked
General Questions
Q: Who holds a Juno Cassandra licence? A: Licences are purchased and held by infrastructure-owning organisations — councils, toll agencies, or national governments. Individual analysts cannot hold their own licences.
Q: What is an “element” in a licence? A: It depends on the type of infrastructure:
- Road networks → number of road segments
- Water networks → number of pipe elements
- Bridge networks → number of structural components (e.g. trusses, piers)
Q: How is pricing determined? A: Primarily on the maximum number of elements allowed in the licence. How many people need access, and what they need to do, is agreed alongside that and may affect the cost. Contact Lonrix for a quotation.
Q: What do we need to install? A: Nothing. Juno Cassandra runs in a web browser and the models run on our servers. There is no software to deploy, no runtime to install, and no version to keep up to date.
For Client Organisations
Q: How do we get a licence? A: Contact Lonrix for a quotation. We will need to know roughly how large the network is that you intend to model, and how you plan to use the software.
Q: How many people can we nominate? A: That is agreed with us when your licence is set up, based on your needs, and it can be revisited later. It may affect the licence cost, so tell us early what you have in mind.
Q: Can we give someone view-only access? A: Yes. A stakeholder account can see the project and its results but cannot change files or start a run. It suits asset managers and executives who want the outputs without the controls.
Q: How do we add or remove people? A: Notify Lonrix of the change and we will action it. Removal is immediate and complete — because everything lives on our servers, nothing is left behind on the person’s computer.
Q: Can we build our own model rather than using the standard one? A: Yes, and it is included in your licence. See For Modelling Analysts and Training.
For Modelling Analysts
Q: How do I get access to a client’s project? A: The licence-holding organisation contacts Lonrix to confirm your nomination and says which access level you need. We then create your account and grant it access.
Q: Do I need to send you my computer ID? A: No. That was a requirement of the earlier desktop version and no longer applies. Your access is not tied to a particular machine.
Q: Can I work for more than one client? A: Yes. One account can hold access to several client projects, and you choose which one you are working in when you sign in. Each of those clients must have authorised you separately.
Q: Can I use one client’s licence for another client’s work? A: No. A client’s licence covers that client’s network only. This is what the audit process exists to enforce.
Q: What happens when I sign in? A: Your credentials and two-factor code are validated, you choose the client project you are working in, and the element limit for that client is checked when you start a run.
Q: Do I need to buy anything myself? A: Only if you intend to build or maintain a domain model. That work is done alongside an AI coding assistant running in Visual Studio Code, and that subscription is yours to hold. Everything else is covered by the client’s licence.
Compliance & Auditing
Q: How does Lonrix ensure licences are not misused? A: Every user signs in individually with two-factor authentication, element limits are enforced on every run, and usage is recorded. We also conduct audits, either randomly or when anomalies are detected.
Q: What kind of usage information is collected? A: Sign-in times, which client licence you work under, and the work you run — enough to confirm compliance.
Q: What if an audit is required? A: Lonrix may contact the licence-holding organisation to confirm that nominated analysts are legitimately working under its licence. All audits are carried out professionally and discreetly.
