- | ===== 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.
