import AgriFarm Smart Model Data into a FIWARE context broker

Your mission, should you choose to accept it, is to import AgriFarm Smart Model Data into a FIWARE context broker.

Walk through Youtube videos related to your task

These Youtube videos have been carefully prepared to help you with this data import task:

• POST and GET Smart Model Data with the Orion-LD Context Broker REST APIs for Smart Devices

More details about your task

• You can import live AgriFarm data if you can find it, or fake AgriFarm data that your team can come up with (see the Example payloads below).
• You could also reach out to existing AgriFarm adopters, who are organizations who already work with these models. You may find some AgriFarm adopters listed below.
• Work with your visualization specialist to decide what kind of data will produce useful visualizations in the project.
• You can import as much or as little AgriFarm data as you wish, but enough to help your visualization specialist create nice visualizations of the data.
• Work with your OpenShift deployment specialist to deploy the data to an Orion LD context broker, or [ follow the instructions to run FIWARE on your own OpenShift Local ] and deploy the AgriFarm data on your own laptop.
• Work with your documentation specialist to document some useful example data used in your project.
• If you are not sure where obtain AgriFarm data, you may want to use your imagination. Imagine if there was a AgriFarm sensor in your actual city, or a AgriFarm sensor in a small scale toy city that you could simulate. What kind of sensors could you use? How would you design such a simulation in an actual city or a toy city? How would you visualize AgriFarm data in an actual city or a toy city?
• With a working Context Broker, you should be able to deploy AgriFarm Smart Model Data as defined in this GitHub issue in the Example payloads section. Save an example JSON payload to a file like ~/Downloads/AgriFarm1.json. Then POST the Smart Model Data to the Context Broker with the curl command: curl -iX POST 'http://orion-ld-fiware.apps-crc.testing/v2/entities?options=keyValues' -H 'Content-Type: application/json' -d @$HOME/Downloads/AgriFarm1.json if using a NGSI-v2 key-values Example.
• Or curl -iX POST 'http://orion-ld-fiware.apps-crc.testing/v2/entities' -H 'Content-Type: application/json' -d @$HOME/Downloads/AgriFarm1.json if using a NGSI-v2 normalized Example.
• If you need to update a payload that was already POSTed to the Context Broker, you can update the values. Update the example JSON payload by removing the id and type fields in ~/Downloads/AgriFarm1.json, but keep track of the value of the id field, because you will need it for the next part. Then PUT the Smart Model Data to the Context Broker with the curl command, but replace ENTITY_ID with the id of the entity URL encoded: curl -iX PUT 'http://orion-ld-fiware.apps-crc.testing/v2/entities/ENTITIY_ID/attrs?options=keyValues' -H 'Content-Type: application/json' -d @$HOME/Downloads/AgriFarm1.json if using a NGSI-v2 key-values Example.
• Or curl -iX PUT 'http://orion-ld-fiware.apps-crc.testing/v2/entities/ENTITY_ID/attrs' -H 'Content-Type: application/json' -d @$HOME/Downloads/AgriFarm1.json if using a NGSI-v2 normalized Example.
• See this documentation for more examples of FIWARE Context Broker API CRUD Operations.

The day of the operation is Thursday February 2nd, 2023

You will have 4 hours to complete your mission.

Work with Smart Data Models and the FIWARE Context broker in Europe

At the end of the day

Should you, or any of your force be taken or compromised that day, you must report back as many changes as you have made, and any knowledge of your actions, by pull request or comments on the issue on the board.
