WIS 2.0

The WMO Information System 2.0 Strategy (WMO No. 1213) publication describes the overall vision, drivers, challenges, and strategic activities to evolve WIS to its next generation.  In 2020, INFCOM-1 EC-73[1]  endorsed an implementation plan, timeline, functional architecture, and the implementation of demonstration projects.

WIS 2.0 Principles

  1. Adopt Web technologies and leverages industry best practices and open standards
  2. Use Uniform Resource Locators (URL) to identify resources (i.e., Web pages, data, metadata, APIs)
  3. Prioritize the use of public telecommunications networks (i.e., Internet) when publishing digital resources
  4. Require provision of Web service(s) to access or interact with digital resources (e.g., data, information, products) published using WIS 
  5. Encourage NCs and DCPCs to provide 'data reduction' services via WIS that process 'big data' to create results or products that are small enough to be conveniently downloaded and used by those with minimal technical infrastructure
  6. Will add open standard messaging protocols that use the publish-subscribe message pattern to the list of data exchange mechanisms approved for use within WIS and GTS
  7. Will require all services that provide real-time distribution of messages (containing data or notifications about data availability) to cache/store the messages for a minimum of 24-hours and allow users to request cached messages for download
  8. Will adopt direct data-exchange between provider and consumer 
  9. Will phase out the use of routing tables and bulletin headers
  10. Will provide a catalogue containing metadata that describes both data and the service(s) provided to access that data
  11. Encourage data providers to publish metadata describing their data and Web services in a way that can be indexed by commercial search engines 

Demonstration Projects

Demonstration projects will be used to illustrate, evolve, validate and/or refine the concepts, solutions, and implementation approach of WIS 2.0. They may also demonstrate some of the key benefits that WIS 2.0 will bring to the WMO community. For more information on the demonstrated projections go to WIS 2.0 Demonstration Projects page.

GISC with the support of Regional Associations engage the transition of their Area of Responsibility toward WIS 2.0

 

WIS 2.0 training plans in place for all Regions

2024

 

 

 

Operational WIS 2.0 Catalogue and portal provided by GISCs Old WIS DAR Catalogue ‘frozen’.

WIS Centres begin to register services in WIS 2.0 Catalogue. Funding options identified to support WIS 2.0 adoption in LDCs and SIDS

MSS solutions implementing new message protocols available from industry

 

 

2026

 

 

 

Original WIS DAR Catalogue deprecated.

Rationalized set of data and services migrated from original WIS to WIS 2.0. 70% of GTS routing table configuration items migrated.

GISCs provide service(s) to support discovery of real-time data from WIS Centres in their AoR that are yet to migrate to new message protocols.

 

 

2030

 

 

 

Migration to use of new message protocols complete – all GTS routing table configuration items migrated and use of routing tables deprecated
