Building Definition Language

A Cartridge is a bounded, identifiable, replaceable engineering Assembly that performs one or more functions through standardized Interfaces.

Every Cartridge shall define:

Cartridge Type and Instance IDs;

Cartridge classification;

host-side Interfaces;

service-side Interfaces;

internal functional elements;

controlled geometry;

mass and center of gravity;

capabilities;

requirements;

dependencies;

connection protocol;

lifecycle state;

Digital Passport;

inspection and maintenance requirements;

safe-disconnection requirements.

Example:

cartridge EndCartridge_EC01 : TimberStructuralEndCartridge {

id: "s05:cartridge:ec01";

classification: structural_end_cartridge;

member: @Beam_B01;

layers {

member_integration: @EC01_Timber_Integration;

transition_protection: @EC01_Transition_Layer;

universal_interface: @EC01_Node_Interface;

}

host_side_interface: @EC01_Node_Interface;

service_side_interface: @EC01_Member_Interface;

passport: @EC01_Digital_Passport;

}

The Cartridge Model shall distinguish:

external controlled geometry;

manufacturer-controlled internal geometry;

structural load-transfer zone;

utility-transfer zone;

sensing and control zone;

protective shell;

service and inspection zones.

A Functional Cartridge may combine several domains:

}

Removal or replacement shall be represented as a lifecycle and configuration change, not as deletion of the Cartridge’s historical identity.
