Fluidware: A Concept for Adaptive Knowledge - Action Systems

This paper introduces Fluidware as a conceptual and architectural class of digital systems that transcends the traditional separation between software, infrastructure, and human cognition. Fluidware systems operate across varying structural states - stability, flexibility, and transience - while preserving coherence of meaning, agency, and context. Rather than functioning as static tools, Fluidware environments enable a continuous coupling between digital structure and real-world action, allowing knowledge, interaction, and intention to co-evolve.In contrast to conventional knowledge graphs or tool-centric platforms, Fluidware emphasizes situated meaning, human-governed structural evolution, and context-preserving modularity. The paper positions Fluidware as a unifying framing for adaptive socio-technical systems and outlines its relevance for the design of future knowledge infrastructures and human-agentic environments.
