[Geoserver-devel] GSIP 200 Promote MapML to extension

Hi,

It was suggested that in order to get this module tested on a nightly basis, it might be worthwhile doing the work to promote it to an extension.

Now I’m willing to do the work, with a little bit of guidance, so I wrote up a GSIP about it over here: https://github.com/geoserver/geoserver/wiki/GSIP-200

We recently committed some tests and bug fixes, Javadoc formatting and viewer/preview improvements, which although they aren’t complete (73% coverage, 49% branch coverage), I intend to improve them as the functionality of the module improves.

Please consider this request and vote on it, if you think it ready for that, and send any feedback to me.

Thank you.

+1 That looks great, I especially like the documentation and that the module includes a layer preview showing the functionality.

I like the enthusiasm and I am sure there will be a follow up effort to maintain the extension.

I have doubts that the module itself is stable enough and has significant users so this is not a +1.
I was inclined to vote 0 because, because I am reluctant to lower the bar on the requirements above which I believe are as important as good code and an active maintainer; the risk is to go down the “because I need it” route.

However, we are not talking about adding anything to core so I am happy to see this going forward.

Thanks for this note.

Yes.

I have doubts that the module itself is stable enough and has significant users so this is not a +1.

Fair. I forgot to mention that the Canadian Forest Service who thought it would be a good idea to implement MapML in GeoServer. I believe they are a GeoServer user for production use, so the closer I can get this to production quality the more likely they are to use it. Probably true for others as well – a chicken and egg problem.

the risk is to go down the “because I need it” route.

The objective of the MapML / Maps for HTML initiative is to get map semantics implemented in HTML, so that a) better, longer-lived mapping applications can be developed on top of a standard base b) user accessibility of maps and map content is provided via a standard. The intention of this module is to lead and track the effort to attain this level of standardization. So right now, I probably don’t actually want too many users. We don’t want to “burn” people with changes to the API, and we would like them to be on board with driving what those changes might be, and to welcome them because they represent steps toward the overall project goal.

Success for the overall project will could almost be signified by removal of this module, although such removal would probably be implemented by integration of the module semantics into core, but anyway, at that time maps should be part of HTML and so on, and custom element or other JavaScript clients won’t be needed to view a map in a web browser.

All in all, I see your point, but still would like to do the work to make the code fitter and more functional, so that people who do use it don’t regret it.

Thank you,

Peter Rushforth

That’s an important point, at least to me. We try to preserve backwards compatibility as much as possible in GeoServer,
upgrades should be transparent (yes, not always possible, unintended side effects of other changes are possible and all that).

The documentation of the MapML module should clearly state that the standard is still ongoing evolution
and breaking changes might happen in the future. A warning block at the very beginning of the docs should do :smiley:

Hi Peter,
note that my +0 is equal to a go, so I am not going to block you.
I am just trying to make everybody remember that the “official extension” label shall be used for something that is:

  • quite stable
  • with a significant user base

Did we always enforce this? Definitely not.
Am I asking to enforce this now? No.

So I am happy to have you move on with this proposal :slight_smile:
