revive Pydap project

[jhamman]

Pydap is "a Python library implementing the Data Access Protocol (DAP, aka OPeNDAP or DODS)." It facilities the streaming of datasets over a network using DAP. Its development and maintenance has slowed over the past few years, despite its continued use (and support in xarray).

This proposal would do the following:

• provide a proof on concept for a pydap server backed by xarray and dask
• provide some much needed developer maintenance to the pydap project and the pydap-xarray backend (not sexy work but absolutely needed)

NumFOCUS project: Xarray
ESIP member institution: NCAR

While I'm definitely a 👍 here I wonder what is the plan to address the second bullet point:

provide some much needed developer maintenance to the pydap project and the pydap-xarray
backend (not sexy work but absolutely needed)

There is an active community around pydap, people are sending PRs, reviewing them, posting issues, etc. I guess that the main blocker would be recruiting more people with the dev privilegies, to get the issues sorted out and the PRs merged. Is someone in touch with a pydap dev?

[shoyer]

OK, maybe pydap is in better shape than I thought :). It's a been a while I followed the project closely.

I did not say exactly that 😄

At the moment there are 13 pending PRs (most from 2017!) and 31 open issues.
Unfortunately the devs are unresponsive and there are some talks about forking it.
That is why I asked the plan for the second item there. I would prefer to avoid forking it but we need a larger dev base to address the PRs and open issues.

Ping @tomkralidis here who may be interested in reviving pydap.

Ping @laliberte @jameshiebert

[tomkralidis]

Thanks @ocefpaf. As a dev I'm definitely motivated to bring Pydap back to life (see https://groups.google.com/forum/#!topic/pydap/p1xKzsaBaHg). Probably talking with the Pydap maintainters would be a good first step. Count me in!

[jameshiebert]

Thanks for the ping @shoyer I wholeheartedly agree that pydap needs some revival and that the devs (coughmecough) have been pretty unresponsive. Sorry, I haven't had a lot of extra bandwidth over the last year. Where should we organize ourselves?

[rsignell-usgs]

I think this is a great idea, but is it a good fit for this funding opportunity (e.g. where $6K will help)?
IMHO we need to know this before we can vote it up for potential ESIP funding.

[tomkralidis]

@jameshiebert can open a Gitter channel for Pydap? Seems like a good start.

[jhamman]

pinging this issue again. @tomkralidis and @jameshiebert - do you have any thoughts on if/how a small ballast of funding could help get things moving on the pydap front again?

[tomkralidis]

@jhamman perhaps it can facilitate a code sprint of some sort, providing dedicated time to bring Pydap back to life.

@jhamman perhaps it can facilitate a code sprint of some sort, providing dedicated time to bring Pydap back to life.

In conda-forge our plans are to facilitate code sprints by supporting the core devs, that do not have funds already, to attend conferences like SciPy and sprint there. The main advantage is that we can recruit more people than the grant alone would allow.

I can open a Pydap Gitter channel from the geopython space, however I would think it's better being opened by the Pydap project itself.

Anything that requires involvement of the original pydap devs seems unlikely to happen right now. That's why we are having this conversation in the first place. Does anyone on this thread have admin rights on the pydap organization?

[tomkralidis]

I do not, but would gladly take on the role to move Pydap forward.
