= 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 [#Layerstates layer states] may block this.


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

||[[Image(source:trunk/images/dialogs/activate.svg)]]|| [wiki:Help/Dialog/LayerList#ActivateLayer Activate] ||`Shift+A+[0-9]`||
||[[Image(source:trunk/images/dialogs/showhide.png)]]|| [wiki:Help/Dialog/LayerList#VisibilityLayer Show/Hide] ||`Shift+S+[0-9]`||

=== Layer States ===
Normally all actions are possible with the data in a layer. But three switches can change this:

||||= Layer State =||= Upload =||= Download =||= Block =||\
||=   Behaviour  =||\
||
|| [[Image(source:trunk/images/layer/osmdata_small.png,link=)]] ||\
|| Default || . || . || . ||\
||
|| [[Image(source:trunk/images/warning-small.png,8,right,bottom,link=)]] ||\
|| Rework || `false` || . || . ||\
|| Warn before upload ||\
||
|| [[Image(source:trunk/images/warning-small.png,8,link=)]] ||\
|| Test/Blocked   || `never` || . || . ||\
|| Download and edit ||\
||
|| [[Image(source:trunk/images/warning-small.png,8,right,top,link=)]] ||\
|| Private   || `never` || `never` || . ||\
|| Only editing ||\
||
||   ||\
|| Locked   || . || . || `true` ||\
|| No action possible ||\
||

The Upload switch can be toggled to `false` with [wikitr:/Help/Action/EncourageDiscourageUpload Upload] the context menu mentioned above. For all other switches the .osm-file must be edited with a text editor:

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

# To warn before uploading. Same as Upload='checked' in 
# the Layer list context menu for the OSM data layer
<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'
<osm version='0.6' generator='JOSM' locked='true'>
}}}

Do we need separate HelpTopics like this while having no GUI? 
[wiki:Help/Action/BlockDownload] and
[wiki:/Help/Action/LockedLayer]
