  This paper introduces the concept of Distributed Intelligent integrated
Sensing and Communications (DISAC), which expands the capabilities of
Integrated Sensing and Communications (ISAC) towards distributed architectures.
Additionally, the DISAC framework integrates novel waveform design with new
semantic and goal-oriented communication paradigms, enabling ISAC technologies
to transition from traditional data fusion to the semantic composition of
diverse sensed and shared information. This progress facilitates large-scale,
energy-efficient support for high-precision spatial-temporal processing,
optimizing ISAC resource utilization, and enabling effective multi-modal
sensing performance. Addressing key challenges such as efficient data
management and connect-compute resource utilization, 6G- DISAC stands to
revolutionize applications in diverse sectors including transportation,
healthcare, and industrial automation. Our study encapsulates the project
vision, methodologies, and potential impact, marking a significant stride
towards a more connected and intelligent world.
