Entities that use, include or otherwise republish City of Austin open data, require a license that provides the legal basis for that use. They often include the license in the product or service they publish. The license is included either explicitly or referenced via a URL or other mechanism. This document provides the definitions, context and summary of the license to be used with City of Austin open data. It also provides a reference to the license itself.
Definition: Information versus Data
The Open Data Portal and the GIS/Map Downloads page of the City of Austin (COA) make a distinction between data and information. This document covers licensing of data. The licensing of information is more complex and is covered in a separate document. Here are some definitions:
Data: Data is in its basic form "raw" and hasn't been analyzed or processed to provide context or specific meaning.
3rd-Party Data: 3rd-party data, in the case of COA, are data that were generated or provided by a non-COA entity like a vendor or non-city government agency. If COA data contain 3rd-party data, then addtional licensing contraints are possibly required.
Information: Information is data that is processed, organized, structured or presented in a given context and consists of things like reports, charts and other human readable documents. It can contain intellectual property (IP) and/or be copyrighted. Information can include video and audio files when presented and consumed in their visual or audible forms rather than processed bit-by-digital-bit by algorithms or computer programs.
Influential Existing Work
Our thinking on licensing and open data has been influenced by excellent prior work done by other entities. We list some of those entities here:
COA uses the Public Domain Dedication License (PDDL) from the Open Data Commons project of the Open Knowledge Foundation.
