Lambda - JSON validator

[briri]

Build a Lambda function that validates incoming JSON

It should be able to handle the full DMP JSON as well as the versions for updating/adding funding and adding related_identifiers

• Build JSON schema docs for each
• Code the validation service
• Return a boolean to the caller
• Allow endpoint Lambdas to invoke this lambda
• Build tests
• Add Lambda to CloudFormation

Opted to make this one a gem since the code needs to be run synchronously from other Lambdas.

Code lives here: https://github.com/CDLUC3/dmphub-v2/tree/main/gems/dmp-json_validator

The gem offers 3 modes:

• 'author' will be used by the createDMP Lambda and updateDMP Lambda (if the caller is the system of provenance)
• 'amend' will be used by the updateDMP Lambda (if caller is NOT the system of provenance)
• 'delete' will be used by the deleteDMP Lambda

Gem includes a full suite of tests and documentation.

Verified that the postDMP is able to use the gem from RubyGems: https://rubygems.org/gems/dmp-json_validator
