Initial Audit Event definitions

Done:

• Initial audit event definitions based on TxMA spreadsheet
• Ordered Nav Bar to include audit events
• Generated JSON schemas
• Refactored build script to be more readable and modular
• Set pattern for event_name in each type
• Descriptions for each event
• Need to minimise slots in nav bar e.g. don't duplicate for each redefinition
• Investigate warnings for bad links
  • Fields which contain '-' are converted to '_'.
• Range / Type needs to be set on slots
• Examples & tests need to be created
  • Test for description being present
• Need to upload json_schemas somewhere
• Cross check with Splunk
• Need input from technical writers for definitions - Raised with Sabrina
• Metadata - Done an example Annotation
• Speak to TxMA about mispelling
