Trustable Software Framework#

Note

The copyright check ignores all files in trustable and its subdirectories. Modified BUILD file in process repository to be reverted after reuse implementation is implemented in tooling.

The Trustable Software Framework (TSF) approach is designed for consideration of software where factors such as safety, security, performance, availability and reliability are considered critical. Broadly it asserts that any consideration of trust must be based on evidence.

The tenets and assertions defined in the Trustable Software Framework can be used to measure an (OSS) project trust score. To calculate the score link evidences to the Trustable Assertions (TA).

This release of XYZ is Trustable. Trustability of the release is based on aggregation of the evidence from all of the Trustable Tenets and Trustable Assertions. The algorithm for aggregation may involve weighting of specific Tenets or Assertions based on project priorities or experience.
