-## 📖 About GIFIS
+<details>
+  <summary><b>🌐 <span style="color:#005fcb">1. Core Schema</span></b></summary>
 
-The **Generalized Immersive Flood Information System (GIFIS) Specification** defines a structured and extensible data model for representing, validating, and publishing hydrologic and geospatial datasets in immersive environments (VR/AR/MR).
+  Defines the **base structure** all GIFIS objects inherit from.  
 
-It provides JSON Schema–based profiles for core entities such as **locations**, **events**, **alerts**, and **flood maps**.
+  **Key Fields:**  
+  - `id` → Unique identifier (`loc-123`, `evt-456`)  
+  - `specVersion` → Namespace + version (`gifis-core@1.0`)  
+  - `schemaRef` → Canonical schema URL  
+  - `metadata` → Creator, license, provenance  
+  - `updatedAt` → Timestamp  
+
+  📄 File: [`core.schema.json`](spec/gifis-core/1.0/core.schema.json)  
+
+</details>
+
+---
+
+<details>
+  <summary><b>📍 <span style="color:#005fcb">2. Location Schema</span></b></summary>
+
+  Represents **geographic locations** where hydrologic or meteorological events occur.  
+
+  **Includes:**  
+  - `geometry` → GeoJSON / 3D Tiles reference  
+  - `properties` → Name, type, region, etc.  
+  - Extends **Core Schema**  
+
+  📄 File: [`location.schema.json`](spec/gifis-core/1.0/location/location.schema.json)  
+
+</details>
+
+---
+
+<details>
+  <summary><b>📅 <span style="color:#005fcb">3. Event Schema</span></b></summary>
+
+  Describes **flood-related events** such as rainfall, discharge, or inundation.  
+
+  **Includes:**  
+  - `eventType` → (rainfall, flood, storm surge…)  
+  - `timeRange` → Start / End time  
+  - `locationRef` → Link to Location object  
+  - Extends **Core Schema**  
+
+  📄 File: [`event.schema.json`](spec/gifis-core/1.0/events/event.schema.json)  
+

-## 🔑 Core Features
+<details>
+  <summary><b>🚨 <span style="color:#005fcb">4. Alert Schema</span></b></summary>
+
+  Represents **hazard alerts** tied to floods or hydrologic events.  
 
-- ✅ JSON Schema–driven validation for consistency and interoperability  
-- 🌍 Support for geospatial formats (GeoJSON, 3D Tiles, glTF)  
-- 🧾 Standardized metadata for hydrologic, meteorological, and sensor data  
-- 🚨 Integration with alerting systems and flood forecast models  
-- 🕶️ Designed for real-time immersive visualization (VR/AR/MR)  
+  **Includes:**  
+  - `alertType` → Flood Watch / Flood Warning / Advisory  
+  - `severity` → Minor / Moderate / Major  
+  - `area` → Linked Location(s) or bounding geometry  
+  - `issuedAt` & `expiresAt` → Validity window  
+
+  📄 File: [`alert.schema.json`](spec/gifis-core/1.0/alerts/alert.schema.json)  
+

-## 🚀 Getting Started
+<details>
+  <summary><b>🗺️ <span style="color:#005fcb">5. Flood Map Schema</span></b></summary>
+
+  Defines **geospatial flood map overlays** for immersive visualization.  
+
+  **Includes:**  
+  - `geometry` → Polygon / Raster reference (GeoJSON, TIFF)  
+  - `properties` → Depth, extent, classification  
+  - `timestamp` → When the map applies  
+  - Extends **Core Schema**  
+
+  📄 File: [`floodmap.schema.json`](spec/gifis-core/1.0/floodmap/floodmap.schema.json)
