Three one-shot Python scripts that build the MELI Fraud As-Is /
To-Be .drawio pair by cloning an Oracle Architecture Center chassis
and overlaying MELI-specific labels, region renames, and workload
pills. Useful as worked examples of the chassis-then-overlay
transform pattern (drawio_template_transform.DrawioTemplate) that
the diagram procedure recommends:
• build_meli_fraud_from_adbsplusadbd.py — clones the locally
accepted ATP-S/ATP-D side-by-side reference and partitions cells
into AS-IS / TO-BE panels by x-coordinate.
• build_meli_fraud_from_crossregion.py — uses Oracle's
exadata-dedicated-cross-region-dataguard ref-arch (two regions
with DRG + RPC + Data Guard already drawn) as chassis and only
overlays MELI-specific pills.
• build_meli_fraud_from_templates.py — combines the in-region and
cross-region Exadata ref-archs and clones the in-region
topology to the right for the Montreal DR.
All three honour the standing rule: do not edit text inside Oracle
SVG stencil shapes — overlay new mxCells in whitespace instead.

"""
|
|
Build MELI Fraud As-Is and To-Be .drawio files by cloning and editing
|
|
examples/output-meli-fraud-adbd-migration/adbsplusadbd.drawio — the ADB
|
|
(ATP-S / ATP-D) reference Diego already accepted visually.
|
|
|
|
Strategy:
|
|
1. Load the source file.
|
|
2. Partition cells into AS-IS (x < 4630) and TO-BE (x >= 4630) panels;
|
|
edges are assigned to a panel based on their source/target cell.
|
|
3. For each output, delete the panel we don't need.
|
|
4. Relabel the title banner, notes, and trade-offs text for MELI.
|
|
5. Clone the ATP-S / ATP-D icon cells (single-cell stencils) to add a
|
|
second workload row (Transactional) and a Clone column (As-Is only).
|
|
6. Add a Montreal DR region panel to the right.
|
|
7. Save.
|
|
|
|
Constraint: interior labels like "OCI Ashburn" / "AD 3" / "AD 2" / "R/W Pool"
|
|
are plain mxCell values we CAN edit — so we rename AD 3 → AD-X, AD 2 → AD-Y,
|
|
adjust R/W Pool label, etc.
