Simple but useful programs to interact with a broker in PHP

We have released two very simple programs to create an entity in a context broker and for removing an entity based on its id.

In fact these programs are working in the test Orion-LD broker option, located here at home -> tools -> test Orion-LD broker

The source code is available at the utils directory and the  data-models umbrella repository



Test an Orion-LD broker populated with the SDM examples

In the tools menu there is a new option “Test Orion-LD broker“.
In this address https://smartdatamodels:1026 there is an Orion-LD Broker installed open for testing purposes. You can check

It is wiped out every hour, on minute 27, and then repopulated with some hundreds of examples (most of the current examples in data models).
