I am genuinely puzzled why SDAP has not started talking about graduation on the dev list. Graduation in the ASF basically consists of a discussion followed by a vote on the dev list, and a discussion followed by a vote on the Incubator list. There are some housekeeping tasks in the middle, and there is a vote by the Apache board at the end, but the email threads drive the process.
I thought it might be useful to see how another project that I mentored, Hop, went through the process. You could use their emails as a template for your process. Can someone (Nga, Stepheny, Riley, ...?) start a discussion thread? 0. 2020-09-26 Hop starts incubation https://lists.apache.org/thread/74r29h49n54705fpfgnv84rbsnkgsbvv 1. 2021-08-11 Discussion on dev@hop https://lists.apache.org/thread/470xwxw8x8qmm4fp82ckqys5zmrq9416 2. 2021-09-10 Second discussion on dev@hop https://lists.apache.org/thread/lx1yhd7qocgczzm5tg88xz49mrbnt2c8 3. 2021-10-15 Discussion on general@incubator https://lists.apache.org/thread/jj46blkwrhf0l31srtzo5j5dcv7zsqz3 4. 2021-11-21 Vote on dev@hop https://lists.apache.org/thread/s8vg1nh1g707s4hhcxjtg1zdccjpjh2k 5. 2021-11-24 Result of vote on dev@hop https://lists.apache.org/thread/sqyps8crdsjpckks37336psz5wvj4q70 6. 2021-11-25 Second discussion on general@incubator https://lists.apache.org/thread/mrx8g5w1xfzx80wtg9l3mrm3q1lkh6ss 7. 2021-12-02 Vote on general@incubator https://lists.apache.org/thread/l1ttdddl5hl2s4b726q1w3obj1kb7j3g 8. 2021-21-08 Result of vote on general@incubator https://lists.apache.org/thread/x4yrl2n2w5wyym6xmlf7obwydj9b5h72 9. 2021-12-15 Minutes of board meeting voting to establish Hop https://www.apache.org/foundation/records/minutes/2021/board_minutes_2021_12_15.txt Julian
