Re: [science-iwg] EclipseCon Unconference
Hi Jay,

that's funny to know. I didn't realized before that NetCDF is build on top of HDF5. The better for us :-).
Is it only NetCDF version 4 and higher or do the old libraries NetCDF 2.2.22 also rely on HDF5?


Cheers,
Philip

Philip,

Yes, NetCDF 4 is built on top of HDF5. The projects are contemporaries. NetCDF was started in 1989 at UCAR and HDF was started around the same time at NCSA.

I don't have any contacts on the NetCDF team, but Andrew might know someone. Andrew?

I agree that we should get people to make projects at and join the Foundation as well as the working group. However, in the science world very few people are going to do that without a tangible demonstration of the benefits and I think that in general the bigger the project the more time it will take for that to happen. So, while we are working on that lofty goal, we should look into getting these things into Orbit.

Hi Jay, hi Torkild, all,

yep, it would be great having more plugins available in the Eclipse Orbit universe :-). I gave a short overview at the last EclipseCon in France how to use/include 3rd party libraries (but most of the people know how to do this):
http://de.slideshare.net/PhilipWenig/eclipsecon-france-2014

From my opinion, we should find a way/strategy how to contact projects and how to convince them to join the Eclipse Foundation except of those who are already part of another Foundation, e.g. Apache Foundation.

@Jay
Are the NetCDF libraries build on top of HDF5? As far as I know, NetCDF is the predecessor of HDF. Anyhow, it was a good step that they switched to a MIT-style license:

The better it would be if they would join the Science Working Group and switch to EPL. Do you have contact to people from the NetCDF team?


Cheers,
Philip

Torkild,

I think it would be very cool for those to go into Eclipse Orbit.

More generally, and this is a technical discussion that made me think of getting a forum, we should think about a larger, cross-platform set of universal binary builds of common scientific libraries that we could get approved through Orbit. For example, in addition to HDF5 we probably need to pick up other I/O libraries like netcdf and exodus II. Both of these are built on top of HDF5 and have BSD licenses, so why not just make it very convenient and build them all together? Other libraries, like math libraries could be added too. An integrated software stack like this is a highly coveted thing in many M&S circles because it would greatly simplify deployment of M&S codes for commercial customers.

Of course this is a technically difficult thing to do and comes with legal questions, so an extended discussion would be best in a forum or bug ticket. But... it would be really cool to just pull down the org.eclipse.science.native bundle(s) from Orbit in a target!

Hi Philip,

This is a great idea! I'd like to contribute if I can. It's up to my client whether or not I can go to the unconference. I've not heard with them yet so I don't know.

One thing we've been working on that we would like to contribute, if we can - are neatly bundled HDF5 binaries for supported platforms. Maybe this can go into Eclipse Orbit. I suspect we're not alone in packaging HDF5 so it would be great to get some input on that. In any case I'll start the CQ process very soon, so maybe we can get a go-ahead before EclipseCon.

Best regards,
Torkild

We could then prepare and commit ideas/implementations until the unconference starts and go deeper in a face-to-face meeting.
