EarthCube’s GeoCODES’ Gleaner Used by United Nations Project to Index Oceanographic Data

The Ocean InfoHub (OIH),  a project implemented by  the International Oceanographic Data and Information Exchange (IODE) of UNESCO's Intergovernmental Oceanographic Commission (IOC), has recently started utilizing GeoCODES’ Gleaner.


“One of our project’s goals is to link digital resources - from major infrastructures to simple websites - across very different operational realities and regional contexts  ,” said Pier Luigi Buttigieg, the project's technology lead. “Gleaner helps us accomplish this by efficiently indexing the rapidly growing volumes of metadata our partners share, as we build a global Ocean Data and Information System .”


A three-year project funded by the Government of Flanders, Kingdom of Belgium and implemented by the IOC/UNESCO, the OIH is demonstrating how regional and thematic partners can co-create and co-maintain systems to find each other's digital assets and build a global commons. OIH's outcomes will be instrumental in the launch of the OceanData2030 Programme of the UN Decade of Ocean Science for Sustainable Development, and its interfaces with other Programmes and Projects as they arise.    


“We were excited that OIH could use our tool,” said Doug Fils with the EarthCube-funded GeoCODES project. “Gleaner has allowed OIH to create a sustainable portal that provides users with a way to find the data they need and we look forward to continuing to support their efforts.” 


GeoCODES is an Earthcube program effort to better enable cross-domain discovery of and access to geoscience data and research tools. GeoCODES is made up of three components respectively.


UNESCO is a specialized agency of the United Nations aimed at promoting world peace and security through international cooperation in education, arts, sciences and culture. The IOC of UNESCO is the United Nations body responsible for supporting global ocean science and services.


Gleaner is a GeoCODES tool that uses a list of sites to index and then the user can access and retrieve pages based on the sitemap.xml of the domain(s). Gleaner can then check for well-formed and valid structure in documents. The product of Gleaner runs can be used to form knowledge graphs, full-text indexes, and other products to drive discovery and use.

About EarthCube

EarthCube is a community-driven activity sponsored by the National Science Foundation to transform research in the academic geosciences community. EarthCube aims to create a well-connected environment to share data and knowledge in an open, transparent, and inclusive manner, thus accelerating our ability to better understand and predict the Earth’s systems. EarthCube membership is free and open to anyone in the Geosciences, as well as those building platforms to serve the Earth Sciences. The EarthCube Office is led by the San Diego Supercomputer Center (SDSC) on the UC San Diego campus.
