Key Features
1

Graph-based repository for CSS blueprint data and metadata.

2

Storage of CSS solutions, facilities, risks, actors and other blueprint entities.

3

CRUD capabilities through the KC REST API.

4

Search among CSS value chains and extraction of best practices.

5

Agreement-based contracts regarding data use by third-party consumers.

6

Integration with the Marketplace for blueprint publishing, discovery, purchase and reuse.

7

Integration with DAMS Connector for harmonised and semantically annotated data exposure.

Input Data Requirements

The Knowledge Core receives structured blueprint entities and relationships, including supply-chain actors, facilities, transport, resources and circular-solution metadata. Assessment information, risks, regulations, ratings and tracked metrics enrich that structure. Interfaces exchange this information with the Marketplace and other services. Consistency of the entity relationships is important for finding similar solutions and exploring reusable knowledge across cases.

Implemented Functions

A graph-based CSS Blueprint schema connects typed entities and relationships. Initial pilot blueprints are stored, and the first integration cycle with the Marketplace and DAMS Connector is complete. A language-model-based knowledge-extraction layer supports the use of project information. The Knowledge Core stores and organises the structured knowledge behind the CSSBoost Open Circularity EcoSphere. It represents Circular Systemic Solutions through value-chain blueprints, connecting information about stakeholders, facilities, transport, resources and supply-chain relationships with assessment and business information. The blueprint structure also includes risks, regulations, tracked metrics, ratings and metadata. A graph-based model preserves relationships between these entities, allowing users and connected services to explore more than a flat list of solutions. REST interfaces support the creation, retrieval and exchange of blueprint information with the Marketplace and other services.

Planned Functions

Complete integration with the updated schema and continue adding and refining pilot knowledge.

Inputs

Structured CSS blueprint entities, relationships, supporting evidence and versioned pilot data.

Outputs

Structured value-chain knowledge and extracted patterns, with expert review supporting the interpretation of automated recommendations.

Interfaces / APIs

Knowledge Core API, Marketplace connection and DAMS Connector. Updated-schema integration is ongoing.
