The opmlProjectEditor explainer needed a light edit. It should make a lot more sense now if you’re a newcomer. Perhaps the most important thing is that it now includes an example that you can open in Drummer to see how it works in an outline editor. OPML has become a really important format for apps that use RSS, but it’s far more broadly adaptable. It’s a good package for a whole app, and you can teach your tools to use the common structure to make it easier to share it with others, to keep a repo current, and to deploy the resulting code. #
