The GeoBlacklight Community is excited to announce the release of our next major version: GeoBlacklight 4.0. This version features official support for OGM Aardvark, and we have enriched the documentation for GeoBlacklight and OpenGeoMetadata.

Baby Aardvark Walking

1. Official support for the latest OpenGeoMetadata schema, OGM Aardvark.

OGM Aardvark is a geospatial metadata schema that was collaboratively developed by geospatial metadata specialists and librarians from twelve university libraries. Launched in 2021, it replaces the GeoBlacklight metadata schema version 1.0 (GBL 1.0). Compared to GBL 1.0, OGM Aardvark features syntactical updates to improve interoperability and incorporates additional fields for better descriptions of a wider range of resources. It is now the recommended schema for all institutions adopting GeoBlacklight.

By default, GeoBlacklight 4.0 displays all human-readable OGM Aardvark metadata values on the item view page, including the new fields for:

  • specifying rights and licenses (see figure 1)
  • categorizing records by class and type (see figure 2)
  • interactive widgets connecting records via seven different types of relationships
