= Context Menu > OSM Data Layer =

Data layers contain 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 ===
OSM data layers have following context menu:

|| [[Image(source:trunk/images/dialogs/activate.svg)]] ||\
|| [wikitr:/Help/Dialog/LayerList#ActivateLayer Activate] ||\
|| **`Shift+A`⤳`[0–9]`** ||\

=== Layer State ===
By default all actions are possible with the OSM data in a layer. But the three switches upload, download and locked can change this:

||||= Layer state =||=  upload =||=  download =||=  locked =||\
||=   Behaviour  =||\
||
|| [[Image(source:trunk/images/layer/osmdata_small.png,link=)]] ||\
|| Default || || || ||\
||
|| [[Image(noupload.png,link=)]] ||\
|| Rework || `false` || || ||\
|| Warn before upload ||\
||
|| [[Image(noupload.png,link=)]] ||\
|| Test/Blocked   || `never` || || ||\
|| Download and edit ||\
||
|| [[Image(nodownloadnoupload.png,top,link=)]] ||\
|| Private   || `never` || `never` || ||\
|| Only editing ||\
||
|| [[Image(wiki:Help/Dialog/LayerList:lock-16px.svg,13,link=)]] ||\
|| Locked   || || ||  `true`  ||\
|| No action possible ||\
||

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

{{{#!xml
# Default file header 
# Implying upload='true', download='never' and locked='false'
<osm version='0.6' generator='JOSM'>

# To warn before uploading: 
# Same switch as 'Upload' in the Layer list context menu
<osm version='0.6' generator='JOSM' upload='false'>

# To block uploads:
<osm version='0.6' generator='JOSM' upload='never'>

# To block downloads:
<osm version='0.6' generator='JOSM' download='never'>

# To lock a file: 
# This implies download='never' and upload='never'
<osm version='0.6' generator='JOSM' locked='true'>
}}}
