v99 v100 13 13 Tags provide meaning to the objects. Without them, any other object would be useless and meaningless. Each of ''three other data primitives'' '''can have multiple tags'''. 14 14 15 [=#presets Often tags used in combinations; '''usually these combinations can be found] in [wiki :Presets presets]'''. But it may be true that tags you need to use are not in presets and you need to know them first.15 [=#presets Often tags used in combinations; '''usually these combinations can be found] in [wikitr:/Presets presets]'''. But it may be true that tags you need to use are not in presets and you need to know them first. 16 16 17 17 Simplest example is [osmwiki:Key:drinking_water drinking_water=yes] - it is present globally and can be applied to every object that provides water. Other example is [osmwiki:Key:leaf_cycle leaf_cycle]=* of trees, it will have less coverage globally (as trees do not grow just everywhere). … … 24 24 [[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. 25 25 26 Only nodes have [ [Coordinates]] in the OSM data model. Ways and relations simply refer to nodes.26 Only nodes have [wikitr:/Help/Concepts/Coordinates Coordinates] in the OSM data model.

Multiple ways can refer to a single node (common node). 31 31 32 A practical meaning of this is demonstrated at the [ [Help/Action/Draw#Commonnodes Draw Nodes]]page. The [Help/Action/MergeNodes Merge Nodes] tool can be used to create common nodes.32 A practical meaning of this is demonstrated at the [wikitr:/Help/Action/Draw#Commonnodes Draw Nodes] page.

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). 47 47 48 Sometimes single area is not enough to represent an object (for example, a lake with an island in it), then you have to use a [wiki :Help/Concepts/Object#typemultipolygon multi-polygon]48 Sometimes 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] 49 49 50 50 === Relations (also an OSM data primitive) === #Relations … … 65 65 Additionally, each object participating in a **relation** can be assigned a **role**, for instance "via" node and "from", "to" ways in type=restriction relation. 66 66 67 [wiki :Help/Relations Help/Relations] covers the most basic tools to create relations in JOSM ([wiki:Help/Dialog/RelationList Relations window], [wiki:Help/Dialog/SelectionList Selection], [wiki:Help/Dialog/RelationEditor Relation editor])67 [wikitr:/Help/Relations Help/Relations] covers the most basic tools to create relations in JOSM ([wikitr:/Help/Dialog/RelationList Relations window], [wikitr:/Help/Dialog/SelectionList Selection], [wikitr:/Help/Dialog/RelationEditor Relation editor]) 68 68 69 69 ==== Most popular types ==== … … 80 80 81 81 Multi-polygon specific tools: 82 * [wiki :Help/Action/CreateMultipolygon create a multipolygon]83 * [wiki :Help/Action/UpdateMultipolygon update existing multipolygon]82 * [wikitr:/Help/Action/CreateMultipolygon create a multipolygon] 83 * [wikitr:/Help/Action/UpdateMultipolygon update existing multipolygon] 84 84 85 85 ===== type=route ===== … … 120 120 121 121 In JOSM, a new object doesn't have an ID (its ID is 0) until it is uploaded the first time to the OSM server. 122 * Under **''[[Image(source:trunk/images/preference.png,20,middle)]] [Action/Preferences Preferences] (F12) -> [[Image(source:trunk/images/preferences/display.png,20,middle)]][Preferences/Display Display Settings] -> Look and Feel''** it is possible to en- or disable the display of objects ids in the windows.123 * With **''File -> [[Image(source:trunk/images/downloadprimitive.png,20,bottom)]] [Action/DownloadObject Download object ...]''** it is possible to download **objects** by Ids. 122 * 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. 123 * With **''File -> [[Image(source:trunk/images/downloadprimitive.png,20,bottom)]] [wikitr:/Help/Action/DownloadObject Download object ...]''** it is possible to download **objects** by Ids. 124 124 125 125 === Object versions and history === … … 134 134 135 135 ==== Information about latest version ==== 136 * **''View -> [[Image(source:trunk/images/info.png,18,bottom)]] [Action/InfoAboutElements Advanced info]''** opens separated windows with informations about selected objects in text format. 137 * **''View -> [[Image(source:trunk/images/info.png,18,bottom)]] [Action/InfoAboutElementsWeb Advanced info (web)]''** opens the **objects 'pages** of selected objects on the [osmwww: OSM website] in your web browser.136 * **''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. 137 * **''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. 138 138 139 139 Alternatively, you can browse the objects directly by entering following address in your web browser: … … 147 147 Each object has a **version**.
