Geospatial discussions at Hydra Connect 2016

October 19, 2016

During Hydra Connect 2016 in Boston this October, we had several discussions around geospatial repository services. There was a half-day workshop and presentation on GeoConcerns -- part of the Hydra Geospatial Data Modeling Working Group chaired by Eliot Jordan; a panel discussion on sharing geospatial metadata; and a meeting of the Hydra Geospatial Interest Group.

Encoding place names using linked data authorities

We discussed drafting a charter for a working group that might be a joint venture with the Hydra Metadata Interest Group on how to encode place names using Linked Data authorities. This approach is a common problem for both geospatial resources and resources with geospatial metadata like place names.

Curation tools for quality control

We discussed the use cases for quality control on federated metadata now that harvesting tools are more available. Blindly harvesting content to federate causes problems for curation and we need approaches and tools for maintaining quality results.

Sharing collection-level metadata and resources

OpenGeoMetadata provides for sharing layer-level metadata, but we do not currently have a way to explicitly share collection-level metadata.

Index maps

We discussed index maps a lot. Many institutions have use cases for discovery via index maps, but we do not have data models nor discovery interfaces that implement effective index map navigation.

For navigation, GeoBlacklight v1.0 provides for simple index map navigation but it does not support many discovery use cases for which index maps are used.

For data modeling, the current GeoConcerns data model, for example, does not provide for a "collection" entity that has with it an index map used as a finding aid or navigation. Geospatial works only have data and metadata, not discovery assets.

Carrying forward discussions at Geo4LibCamp

We're looking forward to discussing these issues further at the next Geo4LibCamp in January 2017. In fact, we hope to make substantive progress on these issues. Fertile ground may be drafting a standard for index map schemas, for example.
