12. Successfull Git Branching Model
http://nvie.com/posts/a-successful-git-branching-model/

13. Simple Workflow
geogig init ltmhh
cd ltmhh/
geogig shp import ../hh_stolpersteine.shp #shapefile that has points
geogig add hh_stolpersteine #add it to version control
geogig commit -m "initial stolpersteine" #commit into repository
<modify features>
#apply changes to repository
#show history and work with a specified version
Demo ...

14. OSM Workflow
geogig osm download --bbox 53.4 8.4 54.0 10.4
geogig osm download --update

15. OSM Workflow
{"rules":[
{
"name":"power",
"filter":{
"power":[]
},
"fields":{
"the_geom":{"name":"the_geom", "type":"POINT"},
"power":{"name":"powertype", "type":"STRING"}
}
}
]}
geogig osm export-shp ./power.shp --mapping ./power.json
