Plays (Field-Calendar)

This relationship models the temporal lifecycle of a Field in the NFT Game Cube solution. A Field defines a sports ground's static, spatial configuration (like a 12×8 football pitch), while Calendar entries dynamically represent individual matches, tournaments, or rounds on that Field.

Examples:

• PSG Champions League 2026

• New York Knicks 2026 NBA Season

Images The images sent using base64 encoding are saved into IPFS using the BWS IPFS Solution. When getting object details, the IPFS URL is returned.
