IndonesianNODC Generate JSON LD Steps

Background

The following steps should be executed by the INA-NODC (BRIN) team. GeoNode currently does not generate JSON-LD for the catalogue layers, so these steps generate JSON-LD for each record the catalogue (https://geonode.nodc.id).

Requirements

• Python 3.x
  • install Python (3.9.12 is recommended)
• pip
  • install pip
• install necessary Python modules
  • python -m pip install json, pyld, owslib, ssl, pandas, kglab, logging

Step 1: Generate the JSON-LD for each layer

• use Python script named ina-nodc-harvest.py from here
• make sure you create a new folder named data-ina-nodc in the same directory as where you have the script
• execute the script: python ina-nodc-harvest.py
• when complete, you should see a message such as:

    ************************
    Parsed 48 records
      33 exported to JSON-LD
      15 were invalid records
    ************************
  

• verify that the folder data-ina-nodc contains several .json files

Step 2: Validate the generated JSON-LD

• use the schema.org validator and paste the contents of one of the generated .json files into the validator (click on 'Code Snippet` and paste there)
