 ===== Open Food DNA =====
-The basic idea is to create an open dataset of DNA information about food and beverages.
+The basic idea is to carry out a citizen science project to compile an open dataset of DNA information about food and beverages.
-Take beer. The assumption is that the DNA content (genetic or genomic information about every single living organism that was present during the brewing) may correlate with the type and taste of the brew.
+Many more details about the project on the dedicated wiki [[http://wiki.hackuarium.ch/index.php?title=Open-Food-DNA|here]].
-We want to build a data workflow from sampling to visualisation to communicate this idea to the public.

 Somebody else (at a [[http://www.whitelabs.com|Yeast provider]] in California) seems to be working on this, too. The american press (including the [[http://www.nytimes.com/2014/05/27/science/craft-beer-at-the-genetic-level.html?_r=0|NYT]]) did cover his project, but there is no data or report available so far.

 ===== Data =====
+Since we do not have data yet, we generated a random dataset using this Octave/Matlab code:
+(generates a random data table and calculate the euclidian distance matrix)
+#!/usr/bin/octave
+% lines : beer samble
+li = 10;
+% columns : species and sub species
+co = 30;
+M = round(rand(li,co))
+O = zeros(li);
+for i = 1:li
+  for j = 1:i
+    O(i,j) = norm( M(:,i)-M(:,j) , 2  ); % euclidian norm
+  endfor
+endfor

+We searched for metadata to add to the data generated and making it look more real. Few of our findings:
