Input Data Requirements

A circular-solution blueprint combines a value-chain description with actors, facilities, resources and their relationships. Supporting information includes assessment data, risks, regulations, tracked metrics and business context. Provider and role information governs contribution and access. Search and comparison draw on this structured content, so a blueprint needs sufficient implementation context to help another stakeholder understand its relevance.

Implemented Functions

The first Marketplace and Knowledge Core integration cycle is complete, enabling exchange and visualisation of stored circular-solution blueprints. Interfaces are being aligned with the revised graph schema. The CSSBoost Marketplace supports the publication, discovery and exchange of knowledge about Circular Systemic Solutions. A central object is the value-chain blueprint: a structured description of a circular solution that brings together actors, facilities, resources, activities, assessment information and implementation context. The service connects a user-facing marketplace with the Knowledge Core, which stores the blueprint structure and relationships. Users can explore solutions through search and filtering, while provider and role-management functions support the organisation of contributions. The wider development includes ratings, licensing and transaction-related mechanisms for the exchange of circular-solution knowledge.

Complete updated KC integration, blockchain transaction functions and communication with APT and TEB; collect pilot feedback.
