Developer Certificate Of Origin In November 2015, the HAT development community decided to standardize on a requirement to adhere to a Developer Certificate of Origin (DCO) for contributions to the HAT open source stacks. The full text of the DCO version 1.0 (the current version as of 2016) is: Developer's Certificate of Origin 1.0

(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license

(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution

personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
