[[JOSMImage(dialogs/history)]] ''ショートカットキー:'' '''{{{Ctrl+H}}}'''

'''OSMのノードやウェイ、リレーションに関する履歴の情報を履歴ブラウザに表示します。''' [[BR]]
== Activation steps ==

* using a shortcut
* using control buttons in [[wikitr:/Help/Dialog/SelectionList#Controlbuttons|Selection window]]
* using [[wikitr:/Help/Menu/View|View menu]]

== Overview ==

* On the left a list of object versions is displayed. Two versions (A and B) are marked with a dot. You can manually place both dots or click on a date or user name to place two dots at once. You can also use the up and down arrows on your keyboard to move the dots up and down.

 * Bottom part is halved in two vertical panels and depending on active tab, items are marked using colours:
  * Green - for anything "new" (node) or "added" (tags)
  * Red - for anything "old" (node) or "removed" (tags)
  * Orange - node was replaced with other node (node) tag or value part was changed (tags)
  * Yellow - used to indicate that way was reversed (details below)

== Basic information about a version ==

The History Browser displays basic information about each object version:

  * the '''object id''', the unique number of the object (displayed in the window title bar)
  * the '''version id''', the unique version number the OSM server assigned to this object version (1, 2, 3,...)
  * the '''date of creation'''
  * the '''user''' who created this version. Click on the link to launch a browser with additional information about the user.
  * the '''changeset id''', i.e. the unique number of the changeset in which this object version was created. Click on the link to launch a browser with additional information about the changeset at osm.org. Click on the [[JOSMImage(dialogs/changeset/changesetmanager,16,middle)]] '''Changeset''' Button to open the [wikitr:/Help/Dialog/ChangesetManager Changeset Manager Dialog]. Click on the arrow on the right of the Changeset button to get a list of links to other external changeset viewers.
  * the '''number of comments''' of the changeset discussion (if availible) with this icon: [[JOSMImage(dialogs/notes/note_comment,16,middle)]]
  * the '''changeset comment''' (if availible)
  * the '''changeset source tag''' (if availible)
  * the '''changeset imagery_used tag''' (if availible)
  * the '''object tags'''

=== Context menu ===
Via a right click on one of the tags you get the following context menu:

== Second tab may change depending on selection ==
=== If a node was selected, coordinates tab ===
The '''Coordinates tab''' displays the longitude and the latitude of the node and the distance of the coordinates of the two selected versions. Additionally version A is highlighted as a red circle and version B as a green circle on the map below.

=== If a way was selected, nodes tab ===
The '''Nodes tab''' displays all nodes of the way with their id. 

The arrow down or arrow up in the heading of the table indicates if the nodes are displayed from first to last or vice versa. This helps to easier inspect reverted ways.

==== Not reversed way ====

Note that both arrows are down:

==== Reversed way ====

If you revert the direction of a way, not all the nodes are reordered in this view, but just the arrow switches and the nodes which are in reversed order get a yellow background. 

In the last change of this way (which is by the way not yet uploaded in this case) the way was reversed, one node removed and two nodes added:

=== If a relation was selected, members tab ===
The '''Members tab''' displays all members of the relation with their id, an icon of their object type and (if set) their role.
