Hi everyone in the discussion,

Thanks for this.
Yes, interesting to begin to look at the Data as a Service (DAAS) capabilities of the DHIS. Would be really useful to be able to have different clients handling data off DHIS, esp with this current 'enterprise architecture' craze.

But Lars, how does your expoze webservice fit into this?

Ime

Required note: As long as we don't call it REST :) REST imples a hypermedia-driven application, so let's stick to calling it what it would probably be: a simple web api.

 Hey be a bit more visionary:) I think this is a great thought. We are getting more and more requests from people who want to use their own presentation layer (Ifakara folks in Tanzania will "make a web-based query tool on top of dhis2", Uganda folks are integrating dhis2 with a CMS etc). I'm envisioning methods for:

- getting all data elements/indicators with (a bit extended) DXF and HTML format responses with embedded links to URLs pointing to a method giving you the full details for each as HTML or PDF.
- getting all indicators with DXF/HTML responses with links to URLs pointing to a PNG chart giving the aggregated vales for the 12 last months.- getting all report tables as DXF/HTML with links to URLs pointing to SDMX-HD/HTML/PDF/Excel representations of the table.
- getting all orgunits for a given parent as DXF/HTML with links to URLs pointing to GIS PNG images, and so on...
There you have your hypermedia-driven application that moves from one state to the next by examining and choosing from among the alternative state transitions in the current set of representations.

This kind of stuff will give potential users an elegant way of integrating dhis2 data into whatever tool they prefer and avoid hacking into the database or fumbling with the source code. If don't want your users to leave, make it easy for them to do so:)
