How do I use it?
-Get the data
-Download the licenses, either all in one, individually (see below) or in specific groups (see above).
-For example, here's how to use curl to access an individual license:
-curl https://licenses.opendefinition.org/licenses/odc-by.json
And here's how to use curl to access the CKAN license group:
-curl https://licenses.opendefinition.org/licenses/groups/ckan.json
Git Access
-You can also get the material as a git repo:
-git clone https://github.com/okfn/licenses
Javascript Access (JSONP)
-We also provide a simple way to get direct access from javascript in the browser using JSONP, by providing versions of the all of the data in the jsonp subdirectory wrapped in a callback function named license_callback.
Thus, the JSONP version of a file named: -
xyz.json
whether it is a license group or an individual license, will be located at:
-licenses/jsonp/xyz.json
-$.ajax({
- url:'https://licenses.opendefinition.org/groups/jsonp/ODC-BY-1.0.js',
- dataType: 'jsonp',
- // you *must* set the callback function to be license_callback
- jsonpCallback: 'license_callback',
- success: function(data) {
- alert('License title is ' + data.title);
- }
-});
-
- license_callback.
