Introduction

Discovery in the WMO Information System (WIS) 1.0 is comprised of WMO Core Metadata Profile, as well as Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) for harvesting and Search/Retrieval via URL (SRU) for search.

To lower the barrier to the discovery of WIS resources, this project will test and evaluate current standards and mechanisms for metadata, search, and harvesting. Using principles of linked data, resource-oriented architecture, and Representational State Transfer (REST), this project will attempt to demonstrate the ease of use for WIS 2.0 stakeholders as well as mass-market integration (web search engines, etc.).

Project description

This project aims to experiment with implementing WMO discovery metadata using the OGC API - Records draft standard (see https://ogcapi.ogc.org/records/ ). This project will also experiment with actionable linkages with demonstration project 1 (AMQP/MQTT), search/access of collections of variables of NWP data, as well as enabling search capability against WIS 2.0 topics.
