Create "Register van Algoritmen" endpoint

[robbertbos]

For the Digilab Fieldlab, we need to create a (mock) endpoint for a register of algorithms. It is fine to start with a single datablob that represents a single algorithm.

This algorithm should be a ruleset from regels.overheid.nl

The blob could look like this but should contain an ACTUAL ruleset from regels.overheid.nl:
(NOTE: this is an example made up, just to give an impression, dataModel and ruleModel will likely change based on discussions with regels.overheid.nl).

          }
        ]
      }
    ]
  }
}

The url of the blob should be communicated to Digilab (through Anne).

There should be data to fill the top part of this screen:

implementation notes

• a new repository with a single file (and possibly a schema) is enough for this ticket
• we would communicate the raw url to this file
• note: dataModel and ruleModel are likely to change from the example above, based on discussions with regels.overheid.nl
• the format is json
• onnx models out of scope for now, but important to choose a format that could support it
