    2424=== Nodes (also an OSM data primitive) === #Nodes
    25 [[Image(source:trunk/images/data/node.svg,20,bottom,margin-right=15,nolink)]] A **node** is an individual point with a defined position. ''With respective tags'' it can be used to indicate shops, benches, individual trees or points of drinking water.

    2727Only nodes have [wikitr:/Help/Concepts/Coordinates Coordinates] in the OSM data model. Ways and relations simply refer to nodes.

    3535=== Ways (also an OSM data primitive) === #Ways
    36 [[Image(source:trunk/images/data/way.svg,20,middle,margin-right=15,margin-bottom=5,nolink)]] A **way** is a sequence of nodes ([https://en.wikipedia.org/wiki/Polygonal_chain a "polygonal chain" from ordinary geometry]). OSM **way** used to represent linear objects, ''with respective tags'' it can used to describe: a river bank, tree row, kerbs in the streets (among other uses).

    4848==== Areas ==== #ClosedWays
    49 [[Image(source:trunk/images/data/closedway.svg,20,middle,margin-right=15,margin-bottom=5,nolink)]] If a **way** is closed, i.e. if the last node is the same as  the first node, it is also called an **area**. Old term for this is ''Closed Ways'' (it is still present at wiki, used in software and by some mappers; other part uses "geometry" when talking just about shape of the objects, without tags).

    5151Sometimes single area is not enough to represent an object (for example, a lake with an island in it), then you have to use a [wikitr:/Help/Concepts/Object#typemultipolygon multi-polygon]

    6060==== Simple explanation ====
    61 [[Image(source:trunk/images/data/relation.png,20,middle,margin-right=15,margin-bottom=5,nolink)]]  A **relation**:
     61[[JOSMImage(data/relation,20,middle,margin-right=15,margin-bottom=5,nolink)]]  A **relation**:
    6262* is a sequence of other objects (nodes, ways and relations)
    6363* as other objects (node, way) - every relation can have their own "tags"
     
    113113Assigned to a way, this set of **tags** indicate, that the way represents a road in a residential area with name ''Main road'' (the German name be ''Hauptstraße'', the English name, which in this example equals to name, is ''Main road''). Speed is limited to 30km/h and heavy goods vehicles (hgv) are not allowed. Furthermore, it's a one way street.
    114114
    115 In the [[Image(source:trunk/images/dialogs/propertiesdialog.svg,18,middle)]] [wikitr:/Help/Dialog/TagsMembership Tags/Membership window] you can assign tags to an object, remove tags from an object, or edit assigned tags.
     115In the [[JOSMImage(dialogs/propertiesdialog,18,middle)]] [wikitr:/Help/Dialog/TagsMembership Tags/Membership window] you can assign tags to an object, remove tags from an object, or edit assigned tags.

    121121
    122122In JOSM, a new object doesn't have an ID (its ID is 0) until it is uploaded the first time to the OSM server.
    123 * Under **''[[Image(source:trunk/images/preference.png,20,middle)]] [Action/Preferences Preferences]''** (or **''`F12`''**) -> [[Image(source:trunk/images/preferences/display.png,20,middle)]] **''[wikitr:/Help/Preferences/Display Display Settings] -> Look and Feel''** it is possible to en- or disable the display of objects ids in the windows.
    124 * With **''File -> [[Image(source:trunk/images/downloadprimitive.png,20,bottom)]] [wikitr:/Help/Action/DownloadObject Download object ...]''** it is possible to download **objects** by Ids.
     123* Under **''[[JOSMImage(preference,20,middle)]] [Action/Preferences Preferences]''** (or **''`F12`''**) -> [[JOSMImage(preferences/display,20,middle)]] **''[wikitr:/Help/Preferences/Display Display Settings] -> Look and Feel''** it is possible to en- or disable the display of objects ids in the windows.
     124* With **''File -> [[JOSMImage(downloadprimitive,20,bottom)]] [wikitr:/Help/Action/DownloadObject Download object ...]''** it is possible to download **objects** by Ids.
    125125
    126126**Note**: The display of object ids in the [wikitr:/Help/Dialog/SelectionList Selection List] can be set in Display Preferences under [wikitr:/Help/Preferences/Display#LookAndFeel Look and Feel].

    140140==== Information about latest version ====
    141 * **''View -> [[Image(source:trunk/images/info.png,18,bottom)]] [wikitr:/Help/Action/InfoAboutElements Advanced info]''** (or Keyboard shortcut:**''`Ctrl+I`''**) opens separated windows with informations about selected objects in text format.
    142 * **''View -> [[Image(source:trunk/images/info.png,18,bottom)]] [wikitr:/Help/Action/InfoAboutElementsWeb Advanced info (web)]''**  (or Keyboard shortcut:**''`Ctrl+Shift+I`''**) opens the **objects pages** of selected objects on the [osmwww: OSM website] in your web browser.
     141* **''View -> [[JOSMImage(info,18,bottom)]] [wikitr:/Help/Action/InfoAboutElements Advanced info]''** (or Keyboard shortcut:**''`Ctrl+I`''**) opens separated windows with informations about selected objects in text format.
     142* **''View -> [[JOSMImage(info,18,bottom)]] [wikitr:/Help/Action/InfoAboutElementsWeb Advanced info (web)]''**  (or Keyboard shortcut:**''`Ctrl+Shift+I`''**) opens the **objects pages** of selected objects on the [osmwww: OSM website] in your web browser.
    143143
    144144Alternatively, you can browse the objects directly by entering following address in your web browser:
     
    152152Each object has a **version**. The **version** is incremented whenever the object is uploaded to the server and the OSM server not only stores the most recent version of an object, but its complete **history**.
    153153
    154 * **''View -> [[Image(source:trunk/images/dialogs/history.png,18,bottom)]] [wikitr:/Help/Action/ObjectHistory History]''** (or Keyboard shortcut:**''`Ctrl+H`''**) opens the History Browser. The History Browser will show you the **versions** of a particular object.
    155 * Alternatively, **''View -> [[Image(source:trunk/images/dialogs/history.png,18,bottom)]] [wikitr:/Help/Action/ObjectHistoryWeb History (web)]''** (or Keyboard shortcut:**''`Ctrl+Shift+H`''**) opens a page on the [osmwww: OSM website] in your web browser which displays the object history, too.
     154* **''View -> [[JOSMImage(dialogs/history,18,bottom)]] [wikitr:/Help/Action/ObjectHistory History]''** (or Keyboard shortcut:**''`Ctrl+H`''**) opens the History Browser. The History Browser will show you the **versions** of a particular object.
     155* Alternatively, **''View -> [[JOSMImage(dialogs/history,18,bottom)]] [wikitr:/Help/Action/ObjectHistoryWeb History (web)]''** (or Keyboard shortcut:**''`Ctrl+Shift+H`''**) opens a page on the [osmwww: OSM website] in your web browser which displays the object history, too.
