Well Documented Parts
In the ten year history of the iGEM competition, iGEMers and users of the Registry have created over 20,000 parts.
In the beginning of iGEM, it was difficult to get experiments to work as expected. As the competition matured and labs became more used to making and testing BioBricks, more things worked, but not much documentation was contributed. Finally, we required iGEMers to submit highly-documented parts to be eligible for medals. This may not seem like a big change for a single team, but makes a big difference with over 200 iGEM teams.
The job or every iGEMer and contributor to the Registry is to make their part as awesome as possible to inspire students to use it in following years. We encourage everybody who contributes to the Registry to complete as much information as possible and to perform as much characterization as possible before sending us a sample. We also encourage teams to add parameters and categories to their parts. We use these metrics to create part tables that are automatically updated when you add categories.
