Abstract
The goal of the OGC Testbed 20 GeoDataCube (GDC) Provenance Demonstrator was to
establish a standardized approach for exchanging metadata and provenance information in
geospatial workflows. By utilizing the GDC API Profiles, this Testbed task demonstrated how
transparency and reproducibility can be ensured, enabling users to access essential details
about data sources and processing methods. This is particularly beneficial for both open science
initiatives and restricted workflows, where traceability and accountability are crucial.
A primary objective of this Testbed 20 task was to enhance the draft GDC API Profiles
specification to enable seamless metadata and provenance exchange for GeoDataCubes. The
work focused on improving interoperability by aligning with established metadata standards and
enhancing the tracking of workflow identifiers, metadata definitions, and remote process chains.
Additionally, the task participants aimed to refine STAC metadata to improve transparency in
geospatial data processing. Supporting open science was another key objective, achieved through machine-readable
outputs. Through these efforts, the GDC Provenance Demonstrator enhances the reproducibility
of both scientific and restricted workflows while providing a reliable and standardized
framework for geospatial data management.
