Micropub - IndieWeb
— Micropub is an open API standard (W3C Recommendation) that is used to create, update, and delete posts on one's own domain using third-party clients, and supersedes both MetaWeblog and AtomPub. Web apps and native apps (e.g. iPhone, Android) can use Micropub to post and edit articles, short notes, comments, likes, photos, events, or other kinds of posts to your own site.
