We are considering to officially provide an attestation of your contributions to SDM.

Before launching it officially we have created a drafted document for those contributors with a valid mail and name (there are people who do not want to disclose their contribution).

Accordingly, if you browse the database of contributors you will see a new column with the heading attestation and a download draft link.

By clicking on that link you can download the draft version of an attestation of your contribution.

We’ll be glad to receive your feedback on this initiative and the format and content of the attestation in the info@smartdatamodels.org address.

You can see an example below

attestation_alberto.abella@fiware.org_dataModel.Agrifood_2022

Now you can see in the right widget a new entry with the link for our channel on discord #smart-data-models, you can also send your question there. (But only once you have joined by using this invitation )

If you need help on discord channel you can browse this link.

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

Although this is pretty straight forward, being coded in PHP allows you to integrate with, in example, in a WordPress site.

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

– create_broker_entity.php

– remove_broker_entity.php

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).

Some examples of queries:

• • List most of the data entities
  • Broker version
  • List RoadAccident example
  • List the value of attribute status in a data model
  • Create an entity.{“id”: “urn:ngsi-ld:aojo:1234”, “type”: “test”, “humidity”: 3, “otherAttribute”: “check”}.
  • List the recently created entity (if you click previous link)
  • Remove an entity (this case )
