Architecture

Architecture of an Inuk node

Main features include :

• Architecture
  
  
  • Peer-to-peer
    
    
    • Better scalability and robustness
    • Easier deployment
      
      
  • Modular
    
    
    • Software Bus + Java Bean Components
    • Easy to extend
      
      
  • Portable
    
    
    • 100% Java
    • Web Application (servlet/JSP)
    • UTF-8 support
    • Plain HTTP 1.1 (Multipart-Body) POST
      
      
• Database : RDF Data Model
  
  
  • W3C standard (2004)
  • Universal, flexible and scalable representation
  • Describe data & meta-data (RDF Schemas)
  • Multiple sources and datasets
  • Version control
  • Merge branches with tip automatically
    
    
• Shell - Forth-like interpreter /compiler
  
  
  • Server-side scripts
  • Fully featured stack-based language with variables, conditionals, loops...
  • More than 50 built-in functions
    
    
• Broker
  
  
  • Simple generic messaging system
  • Manage channels and subscriptions
  • Broadcast messages: Subscribers can be notified of Inuk events such as database changes, geocoding, indexing.
    
    
• Intégration
  
  
  • All potentially long-lasting server processes run asynchronously
  • clients post data and spawn integration processes such as geocoding, or indexing
  • clients can get task execution time estimates and/or subscribe to task completion events
  • resources can be integrated manually (typically through a web interface) or automatically (typically by running batch scripts)
    
    
• Search engines :
  
  
  • Full-Text search
    
    
    • Generic and custom analyzers for specific grammars
    • Wildcard search
    • Proximity (Levenshtein distance) search
    • Range search (e.g. Dates)
    • Term Boost
    • Boolean & Grouping Operators
    • Ranked results
      
      
  • Phonetic search
    
    
    • Available encoders: Metaphone, Double Metaphone, Soundex, Refined Soundex, Phonex
    • Results sorted by match scores
      
      
  • Spatial search
    
    
    • Search n * nearest resources within specified distance
    • Results sorted by distance from origin point
      
      
  • Temporal search
    • Search resources based on temporal availability (e.g. Opening Hours)
      
      
• Geocoder
  
  
  • Geocode or Reverse-Geocode
  • Based on SGP4 Location Utility Service API (other APIs upon request)
    
    
• Support
  
  
  • Web-based console suitable for testing, development  and administration
  • Java SDK
