Metrolane Guide

How do you build a synthetic enterprise that behaves like a real one?

Metrolane is more than a set of sample records.

It is a synthetic company built across independent business systems, with its own customers, employees, products, orders, documents, integrations, enterprise identities, history and intentional inconsistencies.

This Guide explains how those pieces fit together — from source systems and canonical data, through documents and retrieval, to Day-0, business time, simulation, EKA and future enterprise agents.

The Journey

  1. 01–03
    Build the company

    Start with one company operating through many independent systems.

    See why business actions, IDs and cross-system handoffs remain source-native.

    DAY-0
  2. 04–05
    Turn data into enterprise knowledge

    Follow source data through extraction, mapping, entity resolution and lineage.

    Then add documents, knowledge and governed retrieval.

    DAY-0
  3. 06–07
    Freeze it and prove it

    Understand Day-0 and why provenance, access, validation and reproducibility matter.

    DAY-0
  4. 08–10
    Make the enterprise move

    Create a runtime estate, give it its own business clock, and let real business processes progress through time.

    PHASE 10
  5. 11–12
    Put AI on top

    See how EKA can reason over structured enterprise facts and retrieved knowledge — and how future agents could eventually act through controlled enterprise interfaces.

DAY-0
Part of the frozen, inspectable reference enterprise.
PHASE 10
Runtime architecture for making Metrolane progress through simulated business time.
FUTURE DIRECTION
Planned direction whose detailed implementation contract is not yet frozen.
EKA V1.1 DIRECTION
EKA is an established V1.1 product direction built on the existing Day-0 enterprise and retrieval foundations. Its final orchestration/tool contract is still a separate design activity.
