    78The **JOSM Validator** is a feature of JOSM which checks and fixes invalid data.

    911== Usage ==
     12* Click on the [[JOSMImage(dialogs/validator)]] ''Validation'' button at the bottom of the validator panel or press `Shift+V` to run the validation process:
     13 * If there are currently no [wikitr:/Help/Dialog/SelectionList selected objects], then it checks all objects in [wikitr:/Help/Dialog/LayerList#LayerButtons the current layer].
     14 * If there are selected objects, then it checks only selected objects.
     15* Most of the errors must be manually fixed, while some of them can be automatically fixed by selecting the error or errors and clicking the [[JOSMImage(dialogs/fix)]] ''Fix'' button. As Validator might not be always perfect, it is still the user's duty to check the result of the action.
     16 * The two tables, [wikitr:/Help/Preferences/Validator#TestsTable Tests] and [wikitr:/Help/Preferences/Validator#MapCssBasedTests MapCSS Tests] offer little more explanation about each the test.
     17* Use the right click menu to "Zoom to problem".
     18* Multiple objects with the same symptom are [wikitr:/Help/Validator/MapCSSTagChecker#Grouping grouped together].
    1019
    11 * Click on the new tick icon [[Image(source:/trunk/images/dialogs/validator.png)]] (''open the validation window'') in the vertical toolbar to show the validator panel on the right (or use the keyboard shortcut: {{{Alt+Shift+V}}}).
    12 * Select the data you want to validate (or deselect to validate everything)
    13 * Click on the ''Validate'' button [[Image(source:/trunk/images/dialogs/validator.png,15)]] at the bottom of the validator panel or press {{{Shift+V}}} to run the validation process
    14 * While some of the errors must be manually fixed, most of them can be automatically fixed. Just select the error or errors and click the ''Fix'' button [[Image(source:/trunk/images/dialogs/fix.png,15)]] to automatically fix them. You can select multiple errors, and all of them will be fixed.
     20The validator is an automatic test tool. It can show you errors in the data, but it is not perfect and may also tell you errors, which indeed aren't errors ("false positives"). Thus every by the validator marked object should be checked by the user before changing it.

    16 The validator is an automatic test tool. It can show you errors in the data, but it may also tell you errors, which aren't real.

    1723
    18 **Don't fix errors when you aren't sure something is really wrong.**
     24The validator will check the data and display all errors, categorized as [[JOSMImage(data/error)]] ''errors'', [[JOSMImage(data/warning)]] ''warnings'', and [[JOSMImage(data/other)]] ''other'', depending on the severity of the error as a list. Additionally a new [wikitr:/Help/Dialog/LayerList validation layer] is added, which shows you where the problem cases are located in the mapview (can be disabled in the preferences). By default only errors of level ''error'' and ''warning'' will be displayed. Warnings of level ''other'' can be enabled in the preferences but produce more false positives and thus need more care from the user.

    20 Validator will check the data and display all errors, categorized as ''errors'' [[Image(source:/trunk/images/data/error.png,15)]], ''warnings'' [[Image(source:/trunk/images/data/warning.png,15)]], and ''other'' [[Image(source:/trunk/images/data/other.png,15)]], depending on the severity of the error.
    21 By default only warnings of level error and warning will be displayed. Warnings of level ''other'' produce a lot more validation errors for valid data and thus need more care from the user.
     26[[Image(validator2.png,link=)]]

     28There are six buttons in the validator panel:
     29||= **Icon** =||= **Name** =||= **Shortcut** =||= **Description** =||
     30||  [[JOSMImage(dialogs/select)]]  || Select || || Select the objects of the selected error. ||
     31||  [[JOSMImage(dialogs/search)]]  || Lookup || || Looks up the selected objects in the error list. ||
     32||  [[JOSMImage(dialogs/validator)]]  || Validation ||  `shift+V`  || Start validation process for current selection or all objects (when nothing selected). ||
     33||  [[JOSMImage(dialogs/fix)]]  || Fix || || Fix an error (only when automatically fixable). ||
     34||  [[JOSMImage(dialogs/fix)]]  || Ignore || || Ignore an error or a group of errors in future tests. Does not work with new objects (`id:0`). ||
     35||  [[JOSMImage(dialogs/fix)]]  || Manage Ignore || || Shows a dialog to change the list of previously ignored errors. ||
    2436
    25 This dialog allows to start a verification process of the data.
     37=== Context Menu ===
     38A right click on listed objects offers following menu:
     39||= **Icon** =||= **Name** =||= **Shortcut** =||= **Description** =||
     40||  [[JOSMImage(dialogs/autoscale/problem)]]  || [wikitr:/Help/Action/ZoomToProblem Zoom to problem] ||  `6`  || Zoom the view to the problem. ||
     41||  [[JOSMImage(dialogs/edit)]]  || Edit ||  || Opens a [wikitr:/Help/Dialog/RelationEditor relation editor] for each [[JOSMImage(data/relation)]] [wikitr:/Help/Concepts/Object#Relations relation]. ||
     42||  [[JOSMImage(dialogs/delete,28,link=,middle)]]  || Ignore for now ||  || Delete the specific entry from the list. This just removes the entry from the list but does not add it to the ignore list ||
    2643
    27 You have 4 buttons in this:
    28 * [[Image(source:/trunk/images/dialogs/select.png)]] Select - Select the objects of the selected error.
    29 * [[Image(source:/trunk/images/dialogs/validator.png)]] Validation - Start validation process for current selection or all objects (when nothing selected).
    30 * [[Image(source:/trunk/images/dialogs/fix.png)]] Fix - Fix an error (only when automatically fixable).
    31 * [[Image(source:/trunk/images/dialogs/delete.png)]] Ignore - Ignore an error or a group of errors in future tests.
     44== Ignore List Management ==
     45[[Image(ValidatorIgnoreListManagement.png,link=)]]
    3246
    33 When a validation process has been finished all results will appear in the list. Also a new validation layer is added, which shows you where problem cases lie in the map.
     47This dialog allows to remove items from the ignore list. You can use the delete key or the right mouse button to remove items. **If you see only numbers and no descriptive texts the list was migrated from older JOSM versions. In this case it is recommended to remove all items and ignore them again to get the descriptive texts shown above.**
     48
     49**Note:** in the context menu of an error in the list there is the entry [[JOSMImage(dialogs/delete,24,middle,link=))]] ''Ignore for now''. This just removes the entry from the list but does not add it to the ignore list. Therefore it will appear again on the next validation run.

    3554== Validation on upload ==
     55If not disabled the validation process is also started on each upload to the server. For uploads only the modified elements are tested. If you abort the upload, the validator panel displays the result of the validation.
    3656
    37 When not disabled the validation process is also started on each upload to the server. For uploads only the modified elements are tested. If you abort the upload, The validator panel opens, if not already open, and the validation results
    38 are copied in the validation dialog, so they can be checked and fixed.
    3957
    40 == Validation layer ==
     58== Validation result can depend on the downloaded area ==
     59Some validator tests include a check whether the tested object is in or out of the downloaded area to avoid false positives. The not downloaded area is displayed with a yellow hatching. Downloaded ways can end in the not downloaded area. If e.g. a waterway ends in the downloaded area then the validator warns that it should be connected to another waterway. If the waterway ends out of the downloaded area then the validator will not warn because it doesn't know if there is really an error because the possible connected waterway was not downloaded. The validator will also not warn if there was never an area download in this data layer (there is no yellow hatching in this layer). Such a layer exists when you e.g. create a [wikitr:/Help/Action/NewLayer new empty layer] or when you download single objects via [wikitr:/Help/Action/Download#DownloadfromOverpassAPI Overpass]. In both cases the data is assumed as incomplete and handled like out of the downloaded area to avoid false positives and a lot unnecessary warnings.

    42 If not disabled through preferences a validator run will open a validator layer.
     61Some validator rules are limited to defined areas (e.g. countries), see [wikitr:/Help/Styles/MapCSSImplementation#Territoryselector Territoryselectors].
