Modules for Backdrop CMS

Provide structured metadata, aka "meta tags", for pages on your site.

Allows you to block IP addresses.
This module restores the lost functionality from the Drupal core.
It also comes with a number of improvements.

Options available:

Video.js is a HTML5-based video player. This means that videos can be played on nearly all devices and
operating systems, provided the right codecs are used.

Elysia Cron extends Backdrop CMS standard cron, allowing a fine grain control over each task and several ways to add custom cron jobs to your site.

Provides IP-based blacklisting through http:BL and allows linking to a honeypot by using Project Honeypot (http://www.projecthoneypot.org/).

A standardized solution for building API's so that external clients can
communicate with Backdrop.

Goals

The diff module is used to show differences between content revisions.
It replaces the normal Revisions tab seen when administering nodes.

The Image Effects module provides a suite of additional image effects that
can be added to image styles. Image styles let you create derivations of images
by applying (a series of) effect(s) to it. Think of resizing, desaturating,
masking, etc.

Status: This project is no longer needed as of Backdrop 1.12 since the
functionality has been added in core.
