Entities
Every thing in the estate is an entity with an identifier: a store, a meter, a camera, a truck.
Working with us · interoperable
Open by design: FIWARE NGSI-LD.
OpsTwin fully adopts the FIWARE architecture. Data moves in and out through an open, standard API, so each project does not need its own custom integration.
The standard
What NGSI-LD is
NGSI-LD is an open API and information model for context information, standardised by ETSI and used across the FIWARE ecosystem.
Properties
What an entity reports or knows: a reading, a status, a location, with the time it was observed.
Relationships
How entities connect: this meter belongs to that store, this truck is on that route.
An example
One meter, described in NGSI-LD
Encoded as JSON-LD, so other systems can read it without a custom adapter.

Why it matters to you
What this means for partners
One model
Every site described the same way
Devices and systems from different vendors land in one information model, so the next site reuses the work of the last.
Fewer bridges
Connect to other FIWARE systems
Systems that speak NGSI-LD exchange data with OpsTwin through the standard API, without a bespoke bridge per bid.
Subscriptions
Changes pushed where they are needed
NGSI-LD lets a system subscribe to changes in context, so the platforms your customer runs can be told when something happens.
No lock-in
Data in an open format
Your customer’s operational data stays in a standard, documented form they can take to other tools.
Where it sits
From devices to decisions
Devices and systems → NGSI-LD context → OpsTwin Live → OpsTwin Pro → Your customer’s platforms
Check the fit
Bring your customer’s systems list. We will walk through how each one connects.
