Data to Action: Increasing the Use and Value of Earth Science Data and InformationFor 20 years, ESIP meetings have brought together the most innovative thinkers and leaders around Earth observation data, thus forming a community dedicated to making Earth observations more discoverable, accessible and useful to researchers, practitioners, policymakers, and the public.

The ESIP Summer Meeting has already taken place, but check out the ESIP Summer Meeting Highlights Webinar: https://youtu.be/vbA8CuQz9Rk.

LTER-core-metabase is a relational database model based on the GCE LTER Metabase, with adaptations by MCR, SBC, and BLE LTER sites.  The project provides a database schema for metadata about ecological data packages. The design is influenced heavily by the Ecological Metadata Language (EML).  There is also an associated R package, MetaEgress, that produces EML for a data package, enabling the information manager to quickly generate metadata for package archiving. The schema and R package are available on GitHub, with the schema represented as a set of SQL scripts to facilitate diffs.  

The Environmental Data Initiative (EDI) is defining a constrained profile of EML to streamline scripts and software for the broader community, but which is not tied to any specific back end storage system. EML was designed to be extensible, but we have observed EML creators converging on a set of elements. De facto then, a profile is emerging, and that profile for EML can define the specs of a common interface, which facilitates writing shared tools against different backend metadata storage systems. For example, LTER-Core-Metabase (a back-end), maps to the EML profile through views that decouple the outward-facing appearance from the back-end implementation. This session will share the current state of LTER-core-metabase and discuss advancing the project and its ties to EDI's profile for EML to improve data management system sustainability.

Information Manager, Moorea Coral Reef Long Term Ecological Research
I curate datasets for an LTER site for reuse in future and current use by other research groups. I am interested in optimizing data usability and making the curation process more efficient. My favorite part of this work is the collegial spirit among LTER site information managers... Read More →
