We had an exciting and productive discussion, but we all came away with the feeling that we have a lot more work still to do on it.</span></div><br><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap;"></span><div style="line-height: 1.15; margin-top: 0pt; margin-bottom: 0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap;">The process has made it clear is that getting a new open source license right is hard - especially one with novel concepts such as the Tidepool License. We need to spend more time carefully considering all of the use cases. Different communities (academics, medical researchers, device manufacturers, patients, etc.) have different requirements, and it’s a challenge to balance all of those needs.</span></div><br><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap;"></span><div style="line-height: 1.15; margin-top: 0pt; margin-bottom: 0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap;">We had been hoping that the process would happen relatively quickly, and we have been waiting until the license was ready before opening up our code publicly. But not developing our code in the open is slowing us down. Tidepool’s vision for an open data platform depends critically on having many eyes on it -- user interface design, API design, testing, and development will all benefit from community commentary and contributions. We have had several people who have offered to contribute, but it’s been challenging to effectively integrate them into our process when our development is happening in private repositories.</span></div><br><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap;"></span><div style="line-height: 1.15; margin-top: 0pt; margin-bottom: 0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap;">We’ve decided we can’t wait any longer.
