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 )

In the context.jsonld of every subject there are long IRI for every first-level attribute and for the names of the entities. See this example.

formerly the link of the attributes took you to an existing web page while the links of the entities take you nowhere. Strictly there is not need to take anywhere, however, it would be useful to create such pages with basic information. Now there are also links to the entities’ pages, where a new page is being created. See this example.

Now all of them have their own page with these sections

• Definition
• Version
• Original Schema
• Contributors of the Subject
• Adopters of the data model
• Examples of the data model
• Attributes of the entity
• Required Attributes

See here the example for the data model Anomaly.
