# Summary of S4-260122: License Proposal for DaCAS-2 Test Script

## 1. Introduction and Background

This contribution from Beijing Xiaomi Mobile Software Co., Ltd. addresses the licensing framework for the DaCAS-2 test script. The proposal builds upon the previous DaCAS-2 test script [S4-251827] and discussions from SA4#134 meeting. The document proposes standardized license text to be used by all contributors to the DaCAS-2 test script.

## 2. Main Technical Contributions

### 2.1 Proposed License Text

The document proposes a restrictive copyright and license framework with the following key characteristics:

- **Copyright holder**: Xiaomi Corporation (2026)
- **Scope of permitted use**: Exclusively limited to development and testing of DaCAS within 3GPP SA WG4
- **Restrictions**: 
  - All other uses strictly prohibited
  - No patent license granted
  - No license granted under any other intellectual property rights
- **Liability disclaimer**: Software provided "AS IS" with no warranties (express or implied) regarding accuracy, completeness, or sufficiency
- **Limitation of liability**: No liability for damages arising from software use

### 2.2 Multi-Contributor Framework

The document provides a template for updating the license when additional contributors join:

- **Copyright expansion**: Allows addition of multiple copyright holders (e.g., "Xiaomi Corporation and [XXX company]")
- **Parallel updates**: Contributor list to be updated in parallel with code changes
- **Consistent terms**: Same restrictive terms and liability disclaimers apply to all contributors collectively

## 3. Conclusion

The contribution seeks feedback from SA4 participants on the preliminary licensing terms outlined in Section 2.1. The proposed framework establishes a mechanism for maintaining an updated contributor list that evolves alongside code modifications as specified in Clause 2.2.
