GeoPackage Standard

==========

GeoPackage is an open, standards-based, platform-independent, portable, self-describing, compact format for transferring geospatial information. The GeoPackage standard describes a set of conventions for storing the following within an SQLite database:

These capabilities are built on a common base and an Extension Mechanism is described to provide implementors a way to include additional functionality in their GeoPackages.

This OGC® Encoding Standard defines the schema for a GeoPackage, including table definitions, integrity assertions, format limitations, and content constraints. The allowable content of a GeoPackage is entirely defined in this standard.

For more information about GeoPackage, including implementations and sample data, go to the public page at http://www.geopackage.org. An HTML version of the standard is available at http://www.geopackage.org/spec/. The asciidoc source for the standard is in the spec/core/ folder.

About

This GitHub repository was originally extracted from the Microsoft Word version of the Candidate GeoPackage Standard version 0.8 released for public comment on August 6, 2013. With this repository the OGC invites collaboration and comments directed at the development and enhancement of this candidate standard.

The repo tracks the latest version of the standard as it evolves. Pull requests for fixes are appreciated, and new functionality will still be considered even though version 1.0 has been adopted. The spec is done in asciidoc a format supported by GitHub, similar to markdown but with some features that make it better for specifications, like automatic section numbering.

Editing and commenting

The GeoPackage SWG is accepting public comments and suggested revisions to the standard via GitHub. This is the first time OGC has supported this mechanism for public comment and review. To suggest changes to the standard please fork the repository and submit a pull request with the desired changes. Please make one pull request per logical requested change and be sure to include a comment in the PR with any justification or reasoning on why the change is needed.

For more general comments (that don't include actual text changes to the spec) please create a GitHub issue for that topic.

Complex changes and feature requests must go through the change request process. The details entered in the change request form will help the SWG adjudicate and prioritize the request.

For more detailed guidance, or if you are new to GitHub, see the Process page for additional information on editing.
