• Catalogue Interoperability Protocol (CIP)

4
Background

• Committee for Earth Observation Satellites (CEOS)
  
• Established in 1984
• Co-ordinates EO data exchange, policies, systems
  and standards
• CEOS Access Task Teams
• IDN (International Directory Network)
• WWW, Network and Browse
• CINTEX
• Protocol

5
Background

• CEOS Inventory INTeroperability EXperiment
  (CINTEX)
• Established in 1994
• Uses IMS VO (Information Management System
  Version 0) protocol
• Provides a level of Inventory and Browse
  Interoperability
• CEOS Protocol Task Team (PTT)
• Established in 1995
• Builds on CINTEX Lessons learnt
• Co-ordinates the Catalogue Interoperability
  Protocol (CIP)definition
• Co-ordinates CIP developments (prototyping)

Background

• Traditional EO catalogues
• Agency specific
• Mission specific
• Product specific
• Isolated
• Separate Guide, Inventory, Directory, Browse
  systems
• Problems
• Increase of data volume and types
• Increase of number of users
• Many disparate tools and systems
• Too specialised
• Lack of common entry point

Drivers

• Service providers objectives
• Service interoperability and reusability
• Easy maintenance and flexibility
• Shared vision and costs
• Larger user group
• International acceptance
• User requirements
• No a-priori knowledge of systems and data
  location
• One-stop shop of EO data and related
  information
• Increased functionality
• Distributed searching, retrieving, ordering

10
Vision

• Assumptions
• Accesses heritage systems (no changes)
• Functions
• Includes standard set of retrieval terms and
  formats
• Is flexible and extendible
• Updates clients dynamically to reflect server
  evolution
• Reports status, error conditions and hits
• Supports anonymous/registered users
• Supports security/authentication
• Supports ordering (ultimate objective)

11
Development

• Release A (March 1996)
• CIP User Requirements Document (CIP URD)
• CIP URD versus Z39.50 Version 3.0 comparison
• CIP-A Specification
• Release B (March 1997)
• Interoperable Catalogue System (ICS) URD
• CIP-B Specification
• ICS System Design Document
• Release B Consolidation (Planned March 1998)

Implementations

• CEO CIP/Z39.50 Prototype (DBV)
• CEO CIP-A Demonstrator
• NASA CIP-B Retrieval Manager Prototype
• ESA CIP/MMBS Gateway
• ESA CIP Client
• CEO Enabling Services

14
Summary

• Evolutionary definition
• Public available software
• International enthusiasm / involvement
• Z39.50 basis for CIP
• International network being established
• Interoperability vision being realised
