= 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** =||= **Behavior** =||\
||
||||= **key name** =||= `upload` =||= `download` =||= `locked` =||= =||\
||
|| [[JOSMImage(layer/osmdata_small)]] ||\
|| Default || || || ||\
|| No special behavior. ||\
||
|| [[Image(Help/Menu/OSMLayer:noupload.svg,link=,middle)]] ||\
|| Upload discouraged ||  `false`  || || ||\
|| A warning before the upload appears. ||\
||
|| [[Image(Help/Menu/OSMLayer:noupload.svg,link=,middle)]] ||\
|| Upload blocked ||  `never`  || || ||\
|| Uploading is not possible, the upload button is greyed out. ||\
||
|| [[Image(Help/Menu/OSMLayer:nodownload.svg,link=,middle)]] ||\
|| 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.svg,top,link=,middle)]] ||\
|| Upload and download blocked ||  `never`  ||  `never`  || ||\
|| The combination of the two states above. ||\
||
|| [[JOSMImage(lock)]] ||\
|| 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.
