[geomoose-psc] Layer Events and Editing

[Dan Little]

Hey Folks!

Some of you may follow the shenanigans of the development team on GitHub
but I know not everyone does! We've been working through a lot of great
improvements in the last two months and as that work has evolved I've been
thinking about the state of editing.

1. Unlike GeoMoose 2.X, 3.X did not include any out of the box editing
capability. GM2.X used a subset of WFS-T in combination with either TinyOWS
or GeoServer. The each had their quirks but it did, for the most part, work.
2. There's not been a priority put on editing in GM3. That's been for a few
reasons:
  A. There hasn't been a lot of dedicated funding for such. The bulk of
GeoMoose development is done under two situations: volunteer and sponsored.
There hasn't been a sponsored version of the development and none of the
develoeprs uses GeoMoose for editing.
  B. The state of current servers isn't great. GeoServer is actively
developed but it's a lot to install and manage to simply be the WFS-T
server. You could use GeoServer to serve all the WMS services as well but
it's not an ask we've been willing to put on users. TinyOWS has not had a
commit or a dedicated maintainer in a very long time. It's hard to
recommend something that does not have a known amount of support.
 C. "Rolling our own" has always been an idea but that's fraught with
potential maintenance disasters as well. Other services have their own
API's for editing but targeting a single API as the basis for editing
support in GeoMoose breaks our goal of being flexible and standards
compliant.
  D. WFS-T, the actual standard, can be cumbersome. Like many standards
WFS-T is pretty feature-complete. It handles all geometry-types, honours
property data-types, all the fun of editing state, projections, and the
rest of the nitty-gritty. But all of that is usually overkill when you just
want to share a layer between a few GeoMoose users.

I'm interested in hearing feedback. Who really had done what? What are the
actual needs?
