H5P enables the creation, sharing and reusing of interactive HTML5 content in your browser. New in Tiki17, this feature has the ability to display H5P objects, as well as an editor to create or modify them.
For more information, see this for the time being:
Tiki17 the file galleries can be configured to detect and process H5P files when they are uploaded, and then they can be embedded in wiki pages using the new H5P Plugin.
To do this go to the File Gallery Control Panel Enchancements tab and enable the feature (you will need to select “advanced” in the filter at the top of the page first), and you can pick a default gallery for them if you like. Then go to a file gallery and upload an h5p file and it will be processed and will be available for use in the plugin.
Note: So far (in Tiki 17.0) you need to add H5P content types by uploading H5P project files before you can create new ones. You can download the types you need from here.
