Shape file import sounds like an ideal task for an external developer, as
it could transform the shapefile content and pipe it into the GML importer
and hence does not require lots of DHIS 2 knowledge.
Lars
Of course shp2gml tools already exist - they could be described as a
bit geeky using the command line. Though there is need for some of
those geeky options for dealing with projection systems and the like.
I think someone with some python know how could write a neat little
QGis plugin to export to dhis2 format which *might* make it easier for
users.

shp2gml is taken care of by ogr2ogr, as described in our manual.
Yes, someone could write a QGis plugin, but why should they, since we are now working on a web app to do this. Granted, it does not (yet) include reprojection, but it does include the other crucial step of generalisation using http://www.mapshaper.org/.

Much better use of developer time would be to include http://proj4js.org/ in Sushil’s app, so that everything needed comes in one sweet package.

That is a handy enough library for dealing with projection all right.
But doesn't really help in reading the shapefile, which *might* be a
bit of a heavy lift for an app dealing with dbf and shp files. I'm
not convinced this would be a really good use of developer time.
QGis already does all the grunt work of reading in the shapefile and
dealing with the various oddnesses. Getting it to dump its output as
dhis orgunits seems like a relatively straightforward proposition.
But you can't assume everyone would want to use qgis.
Maybe another approach would be to create a simple less geeky ui on
top of ogr2ogr. dunno really. I'm not seeing a silver bullet here.

My point is that mapshaper already reads the shapefile, and Sushil’s app built around it already exists.
You are right that some shapefiles are really heavy (thus the need for mapshaper).

DHIS2 currently has no use for GML other than as one of several possible routes for importing shapefiles, so we don’t really care about shp2gml if we can bypass it completely. It is probably nice to have the GML endpoint for external developers who want to pipe geometries into DHIS2 from external systems (remains to be seen if anyone will wish to do so).

Ah, didn't know about mapshaper .... so we already have the library to
read the shapefiles. In which case you are right. Do it all in the
app.
