= Context Menu > OSM Data Layer =

A Data layer contains map data objects downloaded from OpenStreetMap or created and edited by users, usually meant to upload them back to OSM. Special [#Layerstate layer states] may block this.


=== Context menu ===#Contextmenu
OSM data layers have following context menu:

=== Layer State ===#Layerstate
By default all actions are possible with the OSM data in a layer.
But the three switches Upload, Download and Locked can change this:

||||= Switch =||= Upload =||= Download =||= Locked =||= Behaviour =||\
||
||||= key name=||= `upload` =||= `download` =||= `locked` =||= =||\
||
|| [[Image(source:trunk/images/layer/osmdata_small.png,link=)]] ||\
|| Default || || || ||\
|| No special behavior. ||\
||
|| [[Image(Help/Menu/OSMLayer:noupload.png,link=)]] ||\
|| Upload discouraged || `false` || || ||\
|| A warning before the upload appears. ||\
||
|| [[Image(Help/Menu/OSMLayer:noupload.png,link=)]] ||\
|| Upload blocked || `never` || || ||\
|| Uploading is not possible, the upload button is greyed out. ||\
||
|| [[Image(Help/Menu/OSMLayer:nodownload.png,link=)]] ||\
|| Download blocked || || `never` || ||\
|| The downloaded data goes into another layer which doesn't block downloads if available. Otherwise a new layer is created. ||\
||
|| [[Image(Help/Menu/OSMLayer:nodownloadnoupload.png,top,link=)]] ||\
|| Upload and download blocked || `never` || `never` || ||\
|| The combination of the two states above. ||\
||
|| [[Image(Help/Dialog/LayerList:lock-16px.svg,13,link=)]] ||\
|| Locked || || || `true` ||\
|| This includes `download=never` and `upload=never` and additionally blocks any editing of the data. ||\
||

The Upload switch can be toggled to `false` with [wikitr:/Help/Action/EncourageDiscourageUpload Discourage upload] in the context menu mentioned above. 
For all other states the switches must be edited in the .osm-file with a text editor.
The switches are optional parts of the osm key in the second line.
