 ====== Metadata  ======
-===== Map Metadata Template=====
+Map metadata files are generated by [[Save Map]] functors when the corresponding metadata option is enabled by marking the apropriate checkbox on the Metadata tab of the functor editor.
-^ Metadata Keyword  ^ Description  ^ Editable Input  ^ Expansion Example  ^
+Once the metadata generation is enabled for a [[Save Map]], each map written by that functor will have an associated metadata file.
-| %TITLE%  | Title of the map  |
-| %DESCRIPTION%  | Description of the map  |
+The metadata file content is created replacing predefined tags or keywords on a template map with input supplied by the user or by the map itself. The metadata file name is created replacing the map file extension with the metadata file extension.
-| %SOURCE%  | Source or project originating the map  |
-| %ORIGINAL_SCALE%  | Original scale of the data from where the map was produced  |
+===== Map Metadata Template Keywords (Tags) =====
-| %PUBLISHERS%  | Publisher of the map |
-| %NUMBER_OF_COLUMNS%  | Number of rows of the map  |
+^ Metadata Keyword  ^ Description  ^ Input Source  ^
-| %NUMBER_OF_LINES%  | Number of lines of the map  |
+| **%TITLE%**  | Title of the map.  | Supplied by the user.  |

-| %NUMBER_OF_LAYERS%  | Number of layers/bands of the map.  |
+| **%ADDITIONAL_CATEGORY_INFORMATION%**  | Additional information about the categories. Used typically to describe the null value.  | Supplied by the user.  |
-| %NULL_VALUE%  | Value representing the null value (no data) of the map.  |
