StratML, or Strategy Markup Language, is the ISO standard for strategy plans and performance reports. See Wikipedia.
There are four ways of working with StratML in StratNavApp.com:
You can generate the StratML for your file on a one-off basis by selecting "Reports & StratML" at the bottom of the Strategy Board, then selecting your options and clicking "Generate StratML". This will generate a one-time StratML output, which you can copy and save if you want.
You can publish your plan as 'public' StratML by clicking "Edit this project" at the bottom of the Strategy Board and then ticking the "Make StratML public" box. Your project will not appear on the list of public StratML (see next point) and will be automatically updated every time you update your plan.
Finally, you can create a new project in StratNavApp.com by importing an existing StratML from the web. Click the 'hamburger menu' icon at the top left of the page, then select "Projects" from the drop-down menu. Finally, click the second round button: "Import".
