status: Phase 1 — Island Falls (in progress)

# Alpha Attribute

**Alpha Attribute** is the product name for our Maine-focused municipal property intelligence and assessing roadmap. **Island Falls is the pilot.** The same platform pattern is intended to scale to **municipalities across Maine**.

## Current stack (this repo)

- **Backend:** PHP 8 + MySQL/MariaDB (`login/api/`, `gis/api/`)
- **GIS:** OpenLayers (`/gis/`), parcel GeoJSON + database fallback
- **Auth & admin:** Roles, activity logs, property admin, user management
- **Public site:** Opportunity Island Falls economic development narrative (`index.html`)

## Regulatory targets (assessing track)

Build these into data models and exports as features land:

- Assessment date **April 1** annually
- **MVR** — Maine Tax Portal Excel export
- Exemptions: Homestead ($25K), Veterans, BETE, Solar/Wind, Blind, Animal Waste
- Current use: Tree Growth, Farmland, Open Space, Working Waterfront
- Commitment books (RE / PP), public-facing summaries
- State lien / notice forms where applicable

## Phases

| Phase | Scope | Deliverables |
|-------|--------|----------------|
| **1** | Island Falls | Unified property card in GIS + DB; exemption flags; commitment workflow shell; MVR export MVP; citizen read-only views |
| **2** | Pilot hardening | Sketch (Konva or OL draw); parcel upload pipeline; select-board ratio / exemption dashboards |
| **3** | Multi-town | Personal property, abatement/transfer, TRIO-style import tooling |
| **4** | Maine scale | Multi-municipality tenancy, optional re-platform (e.g. PostGIS) if required |
