OGC seeks public comment on GeoPackage Related Tables Extension

Extension will enable features in a GeoPackage data store to reference
related content, such as photos or other multimedia content.

22 August 2018: The Open Geospatial Consortium (OGC) seeks public comment
on the GeoPackage Related Tables Extension.

The GeoPackage Related Tables Extension (RTE) defines the rules and
requirements for creating relationships in a GeoPackage data store between
geospatial or attributes data tables and other tables that contain or
reference related content, such as attributes or media. One use case for
this extension is to associate features with related multimedia content
such as photographs, audio or video files, and/or PDFs.

There are many examples of where the RTE can be used, including relating
parcel (land lot) features to pictures of that parcel, or linking census
boundaries to the related demographic census data.
This extension, like all GeoPackage extensions, is intended to be
transparent and to not interfere with GPKG compliant, but non-supporting,
software packages. The OGC GeoPackage (GPKG) Related Tables Extension
Interoperability Experiment
verified that the extension is correctly designed to meet the design goals
and to be transparent in this manner. The goal of the IE was achieved by
building GeoPackages containing embedded multimedia content and sharing
those GeoPackages with other software products. This IE produced an OGC
Engineering Report
(published soon) that discusses whether the extension is fit for use and
adoption by the OGC.

The candidate GeoPackage Related Tables Extension draft standard
is now available for review and comment. Comments are due by 21st
September, 2018 and should be submitted via the method outlined on the
GeoPackage Related Tables Extension GitHub Issue Tracker
