You may create publicly available URLs of PDF versions of the presentations in a Session or a Day Conference. To do this, click the Settings... button in the "Publish Presentations" section on the right.
Publishing creates public links to PDF versions of the uploaded PowerPoints (and PDF presentations). You can choose between downloading and hosting the PDFs on your own server, or use the links directly.
The published presentations URLs can be downloaded in text or JSON format, and comes in a structured document giving meta-data to each url, such as presenter name and presentation title.
The JSON formatted text is meant to be machine read by content management systems (CMS) and other web publishing tools. Feel free to reach out to firstname.lastname@example.org regarding integration towards your favoriote CMS or publishing system.
