**(For experts only)**

An OSM [wikitr:/Help/Dialog/LayerList data layer] can be set to block any modification and implying the states [wikitr:/Help/Action/EncourageDiscourageUpload upload='never'] and [wikitr:/Help/Action/BlockDownload download='never'].

== States ==

||= '''icon ''' =||= '''state''' =||= '''osm element attribute''' =||= '''behaviour''' =||= '''how to set in GUI''' =||
|| [[JOSMImage(layer/osmdata_small)]] || (no change) || (optional: `locked='false'`) || no special behaviour || the default state  ||
|| [[JOSMImage(lock,13px)]] || locked || `locked='true'` || modification of the data in this layer is not possible and uploads and downloads are blocked ||  not possible ||

== Code Example ==

Edit a .osm file in a text editor and use instead of the usual \\
`<osm version='0.6' generator='JOSM'>` \\
use \\
`<osm version='0.6' generator='JOSM' locked='true'>` \\
