The goal of single-window metadata search has been common across polar science and research communities for decades. Given the diversity of nations, institutions, and scientific communities that collect data in the polar regions. At the moment, there are more than 50 data catalogues of significant interest to polar researchers. This fragmentation makes it difficult for potential data users to find the most relevant data to address a particular question. Federated search allows users to search multiple metadata catalogues simultaneously, while avoiding many of the technical challenges associated with duplicating and translating metadata records between different standards. These challenges include mismatches between vocabularies, and the difficulty in keeping translated metadata records up-to-date when the original record is amended.

Current Progress

The objective of this activity is to develop recommendations on a common set of metadata elements relevant across Polar sciences, to facilitate interoperability and sharing between Polar data repositories and online portals. To start, this effort will focus on identifying Polar data centres or initiatives that have established a metadata template/schema/profile etc.. Initially, a limited set of disciplines or focus areas will be identified to make the scope manageable. Wherever possible and practical, the effort will build on and/or contribute to other related initiatives.

With the help from the POLDER Working group -- POLDER is a collaboration between the Southern Ocean Observing System, Arctic Data Committee, and Standing Committee on Antarctic Data Management. After extensive exploration, POLDER has settled on schema.org as a lightweight interchangeable format for metadata, as it can be easily implemented by source catalogues to broker their metadata standards to a common framework that can be easily indexed by a central search tool. Anyone can explore this tooling and learn more at https://search.polder.info

The Arctic Data Committee also supports similar initatives such as:

• Polar Observing Assets Working Group (POAwg) - RoPON Network
  • About: Portal indexing Observing assets in both Arctic and Antarctic spaces
• SAON Data Portal - https://data.arcticobserving.org 
  • About: Portal indexing Arctic Data

Background

The Polar Federated Data Search Working Group investigated options for developing the tools that underpin federated search for our community, while building on global initiatives and existing tools like GEOSS and the Arctic Data Explorer. The Working Group reports to the Arctic Data Committee (ADC), Standing Committee on Antarctic Data Management (SCADM), and Southern Ocean Observing System (SOOS). As well as exploring the available tools and platforms, the Working Group will seek funding and resources to develop federated search tools.
