What is Open Data?
Open data is non-confidential, public data provided for unrestricted use. The Open Data Handbook at www.opendatahandbook.org is suggested for a detailed discussion. In summary, there are three key characteristics of open data:
- Open data must permit reuse and redistribution. Members of the public can download, reuse, and redistribute open data and as often as desired.
- Open data must be available with no discrimination against fields of endeavor. For example, there are no restrictions against commercial use; members of the public can use open data to create for-profit goods and services.
- Open data must be available in convenient and modifiable form. This means published online, in an open and ‘machine-readable’ format, so that members of the public can use any standard software to import, analyze, and otherwise use the data. For example, a customized Microsoft Excel spreadsheet with data would not be considered ‘open’, but a data file that can be imported into any spreadsheet program could be.
What is an Open Data Portal?
An Open Data Portal (ODP) is a web presence established to serve as the single point of access for open data. Most ODPs include a framework for requiring ‘metadata’ (information about each data set, including who collected it, when it was collected, and when it will be updated). In addition, ODPs provide a set of basic tools to create charts, graphs, and other ‘visualizations’, so that visitors who do not want to download the data can explore it in place.
