BlockOwn

Concept

1. The owner of every block that is placed on your server is saved.
2. Players can protect their blocks and entities against other players.
   1. Protection is based on materials. For example all of an owner's stone blocks or all redstone torches can be protected against other players
3. Owners can add friends, who can access their protected blocks.
4. Owners can lock materials, so not even friends can access them (e.g. chests).

What are Materials?
This plugin identifies the type of owned things by "Materials" which can either be on of these, any type id (I guess you are familiar with them) or one of these.
That means you can own normal blocks AND entities (like item frames or animals) with BlockOwn.

Translations
BlockOwn is on crowdin! If you want to translate BlockOwn to your language, you can easily help with it now! Just visit the BlockOwn project page on crowdin
The translations are not provided within the BlockOwn.jar at the moment, so if you want to use one of them, you can <a href="https://drive.google.com/open?id=0ByrehF-VA20bfndzSGt1XzNodmpITTJQelRtM3YxU05NZE5HVFhDM3Y2MEFCVHV1elZuR2s&amp;authuser=0" target="_blank" class="externalLink" rel="nofollow">download it here.
You'll probably want to start the server JVM with the "-Dfile.encoding=UTF-8" argument if the translation contains special characters (ä, ö, ü or so).
