HoloSphere

HoloSphere is a decentralized geospatial data management system that combines hierarchical hexagonal tiling (H3) with distributed data storage (GunDB) and AI-powered processing of information.

Features

• Hierarchical Spatial Data: Uses Uber's H3 spatial indexing system for efficient geospatial data organization
• Decentralized Storage: Built on GunDB for peer-to-peer data storage and synchronization
• Schema Validation: JSON Schema validation for data integrity
• AI Processing: Extensible AI-powered content analysis and summarization across hexagonal regions
• Voting System: Built-in delegation and voting mechanisms for collaborative decision-making
• Multi-scale Operations: Automatic content propagation across different spatial resolutions

Dependencies

Core Dependencies

• h3-js: Uber's H3 geospatial indexing system
• gun: Decentralized graph database
• ajv: JSON Schema validation
• lodash: Utility functions

Getting Started

npm install holosphere

Basic Usage

import { HoloSphere } from 'holosphere';

// Initialize HoloSphere with your configuration
const holo = new HoloSphere({
  peers: ['http://localhost:8765/gun'],
  aiProvider: 'local' // or 'openai', 'azure', etc.
});

// Create or access a hexagonal region
const hex = await holo.getHex('8928308280fffff');

// Store data in the region
await hex.put({
  type: 'observation',
  data: {
    temperature: 22.5,
    timestamp: Date.now()
  }
});

// Subscribe to changes
hex.subscribe(data => {
  console.log('New data:', data);
});

Advanced Features

Spatial Queries

// Find all hexagons within a radius
const hexagons = await holo.findWithin({
  lat: 37.7749,
  lng: -122.4194,
  radius: 5000 // meters
});

// Query data across multiple resolutions
const aggregatedData = await holo.aggregate({
  hexIds: hexagons,
  resolution: 7,
  method: 'average'
});

AI Processing

// Process content with AI
const summary = await hex.processContent({
  processor: 'summarize',
  options: {
    maxLength: 100
  }
});

// Analyze trends across regions
const analysis = await holo.analyzeRegion({
  hexIds: hexagons,
  timeRange: '7d',
  metrics: ['sentiment', 'topics']
});

Voting and Governance

// Create a proposal
const proposal = await hex.createProposal({
  title: 'Update Data Schema',
  description: 'Add new fields for environmental metrics',
  changes: {
    schema: newSchemaDefinition
  }
});

// Cast a vote
await proposal.vote({
  support: true,
  weight: 1.0
});

Configuration

HoloSphere can be configured with various options:

const config = {
  // Network configuration
  peers: ['https://peer1.example.com/gun', 'https://peer2.example.com/gun'],
  
  // Storage options
  storage: {
    type: 'indexeddb',
    namespace: 'my-app'
  },
  
  // AI processing configuration
  ai: {
    provider: 'local',
    model: 'gpt-3.5-turbo',
    apiKey: process.env.AI_API_KEY
  },
  
  // Schema validation
  schema: {
    strict: true,
    customValidators: {}
  }
};

const holo = new HoloSphere(config);
