MISMO Engineering Guidelines (MEG) 45

MEG 0045 Representing MISMO Data Structures as Objects in an API Environment has been updated to include the following modifications: 

  • Addition of directions for enclosing enumeration values in double quotes
  • Updated the metadata values to correct data types that are invalid in Open API 3.0
  • Minor edits for clarity  

    MEG 0045 creates a representation of the MISMO data objects and structures in a format that is easily consumed by API tools. Use of these representations will allow API developers to utilize the MISMO data standard more readily and will also facilitate the use of the MISMO data standard in JSON messages.
