The @context, located on the root of the github repository, of the initiative is now updated automatically.

The long URLs are now completely significative because either they point to the original URL of the property or they point to the terms.jsonld file where the definitions based on the existing data models are present.

We’ve submitted into the utils directory a short script for installing and running an instance of NGSI v2 and to create your first entity and to list it. It is not a complete guide which is available at FIWARE mains page in this link.

# 1.- if your are coming from a clean installation
sudo docker pull mongo:3.6
sudo docker pull fiware/orion
sudo docker network create fiware_default
sudo docker run -d –name=mongo-db –network=fiware_default –expose=27017 mongo:3.6 –bind_ip_all –smallfiles
sudo docker run -d –name fiware-orion -h orion –network=fiware_default -p 1026:1026 fiware/orion -dbhost mongo-db

# 2.- In case you already had a installation it is better to run these instructions
docker stop fiware-orion
docker rm fiware-orion
docker stop mongo-db
docker rm mongo-db
docker network rm fiware_default

# 3.- Check that your installation is up and running
curl -X GET ‘http://localhost:1026/version’

# 4.- Create your first entity
curl -iX POST ‘http://localhost:1026/v2/entities’ -H ‘Content-Type: application/json’ -d ‘

# 5.- List the entity you have created
curl -G -X GET ‘http://localhost:1026/v2/entities’ -d ‘options=keyValues’

We are in the way of creating a service for testing purposes for getting payloads according to a data model.

The service is under debugging, so it cannot be trusted for production purposes. Let us know issues here

In order to access it has to access this URL (https://smartdatamodels.org/extra/payload_generator.php) with these two parameters token and dataModel

I.e. with a weather observation in the link below:

https://smartdatamodels.org/extra/payload_generator.php?token=sSdme8954c9&dataModel=%22WeatherObserved (reload page several times for generation)

In the production stage, there will be necessary a token in order to, if necessary, to limit the access for a single user. Additionally, it should be available the options of normalized and keyvalues and for the NGSI v2 and LD.

Comments are welcomed

Whenever there is measurement it could be necessary to use the unitCode for setting the units for the value.

Now the guidelines for the data model’s creation include the place to find out these unit codes. See section units.

The list of UN/CEFACT Common Code (3 characters) can be download from this page. Or the list directly from here.
