// set up data transfer manager
var dataTransferManager =
Windows.ApplicationModel.DataTransfer.DataTransferManager.getForCurrentView();

// create event listener to be called on to fill out data package

// fill in data package with what to share
var request = e.request;
request.data.properties.title = "Title for data";
