This tutorial teaches FIWARE users how to architect and design a system based on **linked data** and to alter linked

data context programmatically. The tutorial extends the knowledge gained from the equivalent

[NGSI-v2 tutorial](https://github.com/FIWARE/tutorials.Accessing-Context/) and enables a user understand how to write

code in an [NGSI-LD](https://www.etsi.org/deliver/etsi_gs/CIM/001_099/009/01.08.01_60/gs_cim009v010801p.pdf) capable

[Node.js](https://nodejs.org/) [Express](https://expressjs.com/) application in order to retrieve and alter context

data. This removes the need to use the command-line to invoke cUrl commands.

The tutorial is mainly concerned with discussing code written in Node.js, however some of the results can be checked by

making [cUrl](https://ec.haxx.se/) commands.

[Postman documentation](https://www.postman.com/downloads/) for the same commands is also

available.
