I'm currently making my first steps in OpenLayers, trying to build a page showing a map where people can add data, which is then saved back in our database.
(Background: Mapping of the distribution of indigenous vegetables. We have some data, but the "crowd" should be able to add their information, too). Similar to this example (but in my case polygons should get added): http://ediblecities.org/
Is this possible with OpenLayers?
And this is maybe a too open question, but how? (a reference to a simple example would already be helpful). It does not seem possible to somehow use the tools offered in the toolbar (OpenLayers.Control.EditingToolbar(vlayer)) for this.
Thanks for taking the time!
