Incubator PMC report for February 2021

The Apache Incubator is the entry path into the ASF for projects and codebases wishing to become part of the Foundation's efforts. There are presently 39 podlings incubating. In January, podlings executed 4 distinct releases. We added no new IPMC members, and none retired. There was one IP clearance in January, and there were no new projects. Goblin graduated last month, and Ratis is up for graduation this month. There was discussion about accepting EventMesh.

This month we were missing reports from BRPC, Doris, Livy, NLPCraft, PageSpeed, PonyMail, Toree, Wayang and Weex. BRPC, Livy, PonyMail and Weex have missed more than one report in a row. It not known why so many podlings failed to report, but I would guess step time of year and world events.

BRPC did not report for the 3rd time, and the IPMC is waiting on the results of a roll call. Roll calls have been sent for Livy and PonyMail. Weex has been asked to consider retirement (again) as they have failed to report several times in a row.

BlueMarlin has been asked to move communication to the dev list or be retired from the IPMC.

S2Graph has been retired.

Weex has again been asked to consider retirement, as they have missed several board reports in a row.

SAMOA did not respond to an email to consider retirement, and the Incubator PMC will discuss retiring the project.

MXNet still has several trademark and branding issues that need to be resolved. The releases containing Category X code still have been finally removed. MXNet brought a release vote to the IPMC general list without the required number of PPMC votes.

Most discussions on the mailing list were around releases and graduations and finding new mentors. There were graduation discussions around Daffodil, DolphinScheduler, Flagon, Goblin, and Ratis.

Are there any issues that the IPMC or ASF Board need to be aware of?

The Training Project has opened up the commit permissions to all the committers of Apache project to make is easy for experts in each area contribute to Apache Training presentations. This was announced in the last week of September 2020. This will open up the project for contributions from other Apache projects.
