The WMO Information System (WIS) enables discovery of authoritative meteorological and hydrological data and supports the collection of data and its exchange between WMO Centres and their users. It is operated and governed according to rules (“technical regulations”) defined by WMO, published in the Manual on WIS (WMO-No. 1060).

The data and products available across WMO are described by metadata records published in the WIS Catalogue. WIS Tech Spec 1 ‘Uploading of metadata for data and products’ (WMO No. 1060 Part IV) requires that metadata records comply with the WMO Core Metadata Profile of ISO 19115, as specified in WMO-No. 1060 Part V.

Search within the WIS Catalogue is based on terms from SRU (ISO 23950:1998) using a combination of text, date/time and geographic location:

Text-based searches shall include: subject, abstract, title, author, keywords, format, identifier, type and coordination reference system Date/time-based searches shall include: creation date, modification date, publication date, beginning date and end date Geographic searches shall include a geographic bounding box. The WIS 2.0 vision recognises that weather, water and climate data and information must be made more easily discoverable and accessible to meet many of WMOs strategic objectives and enable WMO to effectively contribute to the UN global agendas.

While the functions of WIS are likely to remain largely unchanged within WIS 2.0, the move to WIS 2.0 embodies a fundamental shift in the approach used for data sharing: from data-oriented GTS distribution to service-oriented access via the Web.

With the move to the Web, a different approach is required to support discoverability of data and products – where prospective users can discover data and products via commercial search engines (Google, Bing, Yahoo, Yandex etc.).

The W3C Spatial Data on the Web Best Practice 2 ‘Make your spatial data indexable by search engines’ describes this approach in further detail. is a collaborative, W3C community activity with a mission to create, maintain, and promote schemas for structured data on the Internet, on web pages, in email messages, and beyond. has support from all the main search engine providers.

This investigation will examine how vocabularies can be used to create structured metadata that is indexable by search engines for weather, water and climate datasets and products published through WIS.

Furthermore, this investigation will review the commonly available mechanisms that enable users to discover weather, water and climate data using date/time and geographic searches.

This investigation should build on existing work commissioned by Geonovum via their GEO4WEB Testbed. Topic 4 of the Testbed examined how could contribute to effective publication of spatial data on the Web. The GEO4WEB Topic 4 report is found here.


This project will provide a report detailing the findings of the investigation.
