Since its inception, OpenViking has established deep academic collaborations with top universities and research institutes worldwide to jointly explore context database design paradigms and best engineering practices for the AI era. This industry–academia collaboration ensures technological advancement while staying closely aligned with real application needs.
We sincerely thank the following scholars for their contributions and guidance in launching OpenViking:
- Associate Professor Sun Yahui, School of Information, Renmin University of China
- Professor Gao Yunjun, School of Software, Zhejiang University; Researchers Zhu Yifan and Ge Congcong
- Associate Professor Dai Guohao, School of Artificial Intelligence, Shanghai Jiao Tong University; Co‑founder and Chief Scientist of Wuwen Xinqiong
Our collaboration models include:
- Joint research projects: conduct frontier research in context engineering
- Technical workshops: organize regular academic exchanges and technical reviews
- Talent cultivation: provide practice platforms and research topics for graduate students
- Technology transfer: transform academic findings into engineering best practices
OpenViking is currently in its early development stage. We divide development into three key phases:
-
Phase 1: Foundation building Focus on constructing solid technical foundations after open-sourcing, including core protocols, interfaces, AI Agent facilities, and providing a reliable minimal implementation.
-
Phase 2: Ecosystem expansion Build a plugin ecosystem, support third-party feature extensions, drive deep integration with mainstream AI frameworks and tools, and extend enterprise-grade capabilities to meet large-scale deployment needs.
-
Phase 3: Industry adoption Establish industry technical standards and best practices, build certification systems and partner ecosystems, and promote broader real-world adoption of context engineering.
Based on the project’s long-term roadmap, we are establishing a layered governance structure:
OpenViking is guided by a professional governance committee responsible for overall strategic planning and technical decisions. The committee consists of core contributors and domain experts, with responsibilities including:
Strategic Planning
- Define the long-term technical roadmap and vision
- Set release plans and feature priorities
- Evaluate the long-term impact of technical decisions on the ecosystem
Technical Governance
- Establish and maintain code quality standards and engineering norms
- Review core architecture changes and major feature implementations
- Ensure sustainability and backward compatibility
Community Development
- Define community development strategy and contributor growth paths
- Organize technical exchange activities and developer conferences
- Build incentive mechanisms and recognition systems
Ecosystem Collaboration
- Establish technical cooperation with related open-source projects
- Promote integration and certification with commercial products
- Manage intellectual property and license compliance
Current core members of the governance committee: Haojie Qin, Jiahui Zhou, Linggang Wang, Maojia Sheng, Yaohui Sun
To ensure openness and diversity, we welcome eligible community contributors to join the committee through future nomination and election procedures.
