What is Negroni

Negroni addresses the challenge of inconsistent data structures across independent applications in an organization. By providing a shared CDM modelling workspace, teams can define canonical data models once and reuse them — reducing custom integration work and keeping data representations consistent.

Core capabilities:

  • Define and manage CDM manifests and entities through a visual interface
  • Import schemas from databases, CDM files, OpenAPI/Swagger/Postman specs, and CDM libraries
  • Export CDM-compliant files, database schemas, data models, or Martini packages
  • Register and discover schemas in the Organizational CDM Registry when your plan includes it
  • Submit manifests through an approval workflow when publishing from the Project Navigator to the CDM Library
  • Manage access through Lonti Account and organization-level permissions
