Nutch Plugin Development

[Timo Schmidt <ti...@gmx.net>]

Hello together,
 
first of thanks for the development on nutch. I've installed nutch 2.1 with hbase and gora on my development system and
started to dive into nutch.

Currently i am working on a plugin to improve the scoring. To start simple, i've implemented a plugin that
is collection facebook like data and attaches it to the document meta data. During this the following question came up:
 
1. What is the proposed way of implementation. By reading existing code i guess:
a) Fetch the like count etc. and attach it to the document meta section and maybe change the score directly
b) Copy the score to a certain field during indexing and use this field for querytime boosting
 
2. What is the best way to make plugins available:
* There are a lot plugins in the core. But how do i provide a third party plugin in the best way regarding compiling dependencies etc?
An example that i found is: https://github.com/ATLANTBH/nutch-plugins/tree/master/nutch-plugins
 Are there other possiblities/examples?
