# Incubator PMC report for May 2020

The Apache Incubator is the entry path into the ASF for projects and 
codebases wishing to become part of the Foundation's efforts. This monthly 
report is in markdown so that it's easier to read. If you are not viewing 
this in that format, it can be seen here:
https://cwiki.apache.org/confluence/display/INCUBATOR/May2020

There are presently 44 podlings incubating. In April, podlings executed 9 
distinct releases. NLPCraft and Pagespeed releases are not yet in the
offical offical
release area. We added three new IPMC members and one retired.

There where no IP clearances in April. There are still four new podlings 
under discussion or VOTE; they are AgenisGraph (voted in but the name needs 
to change), BlueMarlin, HBlock and Liminal (was Rainbow). One project, 
ShardingSphere, graduated last month and one podling Tamaya retired. At 
least one podling is heading towards graduation in the next few months, the 
next one to graduate is likely to be Hudi. This month we were missing 
reports from Pinot, S2Graph, SDAP and ToreeSDAP. All podlings were contact and 
no response so we will need to check if the PPMCs are active. PageSpeed 
didn't get mentor sign off in time. All will be asked to report next month. 

Last month Gobblin complained that they didn't get sign off from their 
mentors and that the IPMC or board should do something about this. The 
pollingpodling and mentors were reminded.  The podling has been asked to check 
with their mentors if this happens again. Without changing policy not to 
require mentor sign off on reports,  I'm not sure what more could be done. 
We have reports missing sign off a couple of times a year.

There was a couple of discussions about the incubator disclaimer notice, 
time limits to incubation and most on list traffic was around releases and 
new podlings.

Three podlings MXNet, SDAP and Spot still need to sort out their roster and 
private mailing list subscriptions.

## DataSketches

DataSketches is an open source, high-performance library of stochastic
streaming algorithms commonly called "sketches" in the data sciences.
Sketches are small, stateful programs that process massive data as a 
stream and can provide approximate answers, with mathematical 
guarantees, to computationally difficult queries orders-of-magnitude 
faster than traditional, exact methods.

DataSketches has been incubating since 2019-03-30.

### Three most important unfinished issues to address before graduating:

  1. Clearly, the most important issue for us is to add more committers.  
     From the Clutch and Podling Website reports, this is the last 
     major issue for us.  

     We have tried to encourage folks that ask questions or raise issues 
     to get more involved, and we have one or two folks that have 
     expressed interest in submitting PRs or even a new sketch. But, 
     alas, none have followed through, yet.  

     Developing sketch code is very tricky and understanding how these 
     algorithms work, and the math and statistics behind them, is a hurdle
     for most people. Yet, we have been very clear that we are prepared to
     train someone to become a committer.  All we ask is that the 
     candidate be open to learning about these fascinating algorithms and
     committed to work with us. We could use some active help from our
     Mentors or from the Board to help us find someone that would find 
     this work interesting.  

     I am convinced that there are folks in the greater Apache community
     that would really enjoy working on this library, we just need to
     discover who they are!  

  2. Referring to last month's report, we have made progress in setting up 
     TODO lists on our major sites: Java and C++. And we keep working 
     away at these lists.  We have also improved our Downloads page and 
     brought it up to Apache standards. I don't feel these should be 
     issues for graduation.  

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

  The issue mentioned above. We could use some help in finding someone
  who would find working in the sketching algorithms area really
  interesting and would want to work with us to become a committer.  

### How has the community developed since the last report?  

  We have been accepted to present at two conferences this Summer, the
  USPTO technology conference and the Spark & AI conference.  

  We also have interest from Apache Flink and Apache Impala to 
  integrate sketches into their systems. There has also been interest
  from Apache Beam, but so far no action.  

### How has the project developed since the last report?  

  We have done a lot of work making the C++ code more robust and will 
  likely have a major new release of the C++ library before this 
  report is read by the Board.  We also in the voting process for a
  new Java release that cleans up some licensing glitches and fixes
  a bug found by Druid.  

  Our activity on Slack has increased quite a bit with 
  interesting queries from all over.  

  We also have done a lot of work on the website, adding content and
  improving navigation. The Community and Downloads pages are all new.
  Please have a look! 

  We continue to improve our release process with more guided scripts
  and fix issues as we discover them.

## ECharts

ECharts is a charting and data visualization library written in JavaScript.

ECharts has been incubating since 2018-01-18.

### Three most important unfinished issues to address before graduating:

  1. Redirecting echartsjs.com to echarts.apache.org. See reason in the 
  next question.
  2.
  3.

### Are there any issues that the IPMC or ASF Board need to be aware of?
  https://echarts.apache.org/ recently changed to a different CDN as a work 
  around for HTTPS CA expiration problem. (See 


  https://issues.apache.org/jira/browse/INFRA-20185?page=com.atlassian.jira.pl
  ugin.system.issuetabpanels%3Aall-tabpanel )
  The CDN change makes the website slow, at least in China as we tested.
  Our next step is to use echarts.apache.org as domain name and use 
  echarts.cdn.apache.org as resource server.
  After fixing this problem, we will redirect echartsjs.com to 
  echarts.apache.org so that the website redirection problem can be finally 
  solved.

### How has the community developed since the last report?
  The community has been more active on the mailing list and pull requests.
  We have been working on encouraging the community to contribute in varied 
  forms and it seems to take effect. We received 23 pull requests from 
  non-committers since last report.

### How has the project developed since the last report?
  We release a new version since last report and is discussing and working 
  on the next big version.

### Is the PPMC managing the podling's brand / trademarks?

  https://github.com/echarts-maps This GitHub user is creating ECharts 
  related projects. We asked him to add notations stating that these are 
  not official Apache ECharts (incubating) project. It has this
  description now:
  "All projects are NOT associated with official Apache ECharts 
  (incubating)
  project and are independently maintained by chfw.". 
  We also asked the author to add this notice to the readme of each 
  projects but he has not finished this yet because there are many projects
  need to change. We are under communication with him about this.

### Have your mentors been helpful and responsive?

  Yes. 

### Is the PPMC managing the podling's brand / trademarks?

  - As far as we know the brand is respected by third parties. We-Amp 
  mirrors the incubator site over at modpagespeed.com - but will work
  on transferring the domain name to the ASF this quarter.
  - It's not known if the VP, brand has explicitly approved, so that is 
  something we need to make sure about and resolve.

     Comments:  I mostly agree with the assessment that Toree is near
                graduation, but is not very active. The community has
                demonstrated it is capable of making releases, adding
                new committers & PPMC members, and welcoming new
                members. My only criticism is how much discussion is
                taking place on gitter rather than the dev list. That
                makes it difficult to keep up, but I think it is
                important to let this community hold discussions in
                the forum that makes sense for it instead of trying
                to make it fit the mold.

### IPMC/Shepherd notes:

## Training

The Training project aims to develop resources which can be used for
training purposes in various media formats, languages and for various Apache
and non-Apache target projects.

Training has been incubating since 2019-02-21.

### Three most important unfinished issues to address before graduating:

  1. Promote the information about Apache Training Project with increased 
     participation from community
  2. Create a tutorial on how the tools provided by this project can be 
     used to create own content
  3. Review current policies around contribution review and releases to 
     find a pragmatic compromise 

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

  Unfortunately, not much has happened since the last report in February.
  We did add one new committer but other than that there has been hardly 
  any activity.
  While we'd like to blame the current situation in the world for this it
  wouldn't be a fair assessment as we had the same problem in the previous 
  period.

  We still believe the idea of the Training project is a good one
  and E-Mails are being responded to so the project is not dead.
  It's a lack of time and dedicated resources that is at least partly
  to blame for this situation.
  We hope that development will pick up again in the future.

### How has the community developed since the last report?
  Activity on the dev list has declined even more since the last report with
  a total number of posts of 34 (most of which are automatted reminders).

### How has the project developed since the last report?

  n/a

### How would you assess the podling's maturity?
  There are currently some issues with this podling that we are working to 
  address, we believe that the issues are not yet critical and can be turned
  around from within the community but want to make the board aware of this
  early on.

  Mentors have been responsive and helpful when reached out to.

### Is the PPMC managing the podling's brand / trademarks?
  The name search process has not yet been started, as there is still time 
  to do that if and when graduation draws nearer. The PPMC is actively 
  monitoring usage of the Podlings current name on other sites. 
  The Podling is not directly affiliating with any sponsors donating 
  content and presenting an independent image on the webpage.

## Tuweni

Tuweni is a set of libraries and other tools to aid development of
blockchain and other decentralized software in Java and other JVM languages.

Tuweni has been incubating since 2019-03-25.

### Three most important unfinished issues to address before graduating:

  1. Finish export notice for cryptographic elements
  2. Vote in a few more committers
  3. Keep release pace and adoption

### Are there any issues that the IPMC or ASF Board need to be aware of?
  No issues to report at this time.

### How has the community developed since the last report?
  We are seeing a few contributions in the bug reports and pull
  requests offered on the repository. The project is starting to
  gain good traction.

  We have seen adoption of the project downstream and a couple
  of fixes contributed as direct result.

### How has the project developed since the last report?

  The project reached 1.0.0, which was a big milestone.
  The roadmap is on Github and more accessible.
  The project is also using Github actions
  to help kick faster CI for pull requests.

### Have your mentors been helpful and responsive?
  1.0.0 took a long time to release, and it's mostly to blame on
  the difficulty to check the release bits.
  We will need to do better there.

### Is the PPMC managing the podling's brand / trademarks?
  Yes. At present, there are no issues nor concerns with the Tuweni mark.
  We do not anticipate any issues with the mark regarding graduation.
