Roughly speaking, Halalan Initiative is a group of people aiming for educated elections by developing software and holding online campaigns that can help people further evaluate candidates/politicians before, during, and after elections. The actual definition is not yet finished but the idea revolves around that.
There are two ongoing projects as of now. First is PolCat which stands for (The) Politician Catalog. The goal is to provide a platform to record information about politicians. The second is Halalan which is a long-standing project of UnPLUG.
