Mapping the Metadata Landscape of Energy Data Repositories

A Multi-Repository Assessment of Conformance to OEMetadata

Abstract

This paper empirically assesses how well energy‑relevant repositories supply the dataset‑ and column‑level metadata required by OEMetadata Schema. Records from ten catalogs are harvested, crosswalked to OEMetadata v2, normalized, and analyzed to compute dataset‑ and resource‑level coverage. Coverage is weak and uneven: provenance and contributor data appear mainly in OEP/OPSD; licenses are absent in half the portals; temporal/spatial metadata are sparse; access URLs are often missing; and column‑level data dictionaries are largely absent. We release crosswalks and a reproducible harvesting workflow, establishing a baseline for measuring and comparing interoperability across repositories.
