Linkback

This module provides multiple Linkback implementations for Drupal 8.

A linkback is a method for Web authors to obtain notifications when other authors link to one of their documents. This enables authors to keep track of who is linking to, or referring to, their articles. The four methods (Refback, Trackback, Pingback and Webmention) differ in how they accomplish this task.

This module defines a flexible Linkback entity (with storage backend API) which can use multiple handlers enabled at the same time. Implemented Linkback handlers are Webmention and Pingback so far in modules within this project. See Developer.md for a list of files, classes and functions in the main linkback module.
