Service Requirements

CESSDA requires its tools and services to be of sufficient quality for sustainable operation.

The quality and acceptability criteria for CESSDA tools and services are defined by the CESSDA Software Maturity Levels and the EOSC Technology Readiness Levels (TRL).

• All applicable Software Maturity Level CAs must reach “Expected”
• The quality gate is relaxed to 50% Code Test Coverage and 10% Duplicated Code Lines

For a software system to be considered as a candidate for future integration, i.e. to form the basis for developing a service, the following criteria must be met:

• All applicable Software Maturity Level CAs must reach “Minimum”
• The quality gate is relaxed to 50% Code Test Coverage and 10% Duplicated Code Lines
