GbBib is a Ruby gem that search and fetch Chinese GB standards. The standards scraped form:

• GB standards - http://www.std.gov.cn/gb/search

• Social organization standards - http://www.ttbz.org.cn

• Sector standards - http://www.std.gov.cn/hb

Note	Unlike the ISO website, the GB websites require the year of publication to be included in the search. So a standard will not be found successfully through this gem unless the year is included in its document identifier: for example, not CN(GB/T 1.1), but CN(GB/T 1.1-2009).

Installation

Add this line to your application’s Gemfile:

gem 'gdbib'

And then execute:

$ bundle

Or install it yourself as:

$ gem install gdbib
