Template:Geography parent category/doc
 | This is a documentation subpage for Template:Geography parent category. It may contain usage information, categories and other content that is not part of the original template page. |
This template formats an information box at the head of a geographical parent category, a category where all or most of the articles are held in sub-categories. It holds information such as notes on the content, Wikimedia Commons category, main article and "see also" links, and may link to a map from OpenStreetMap showing the coordinates of child pages. For a diffused parent category, it may provide a link to a canned PetScan query that gives a consolidated list of pages in the child categories. For a non-diffused category, it may provide links to PetScan queries on articles in child categories but not in the parent and articles in the parent but not in any child category. The PetScan links and the map should be useful in maintenance.
This template may replace {{All included}} for non-diffused geographical categories, and may also replace {{Cat main}}, {{See also}}, {{Category see also}} and {{GeoGroup}}, presenting the same information in a less cluttered and more consistent format.

Parameter names and descriptions

Parent information: rendered only if |metacategory= or |sample_child= are specified
| |
| child_level | Administrative level of child categories, e.g. county, canton, department. Optional. |
| metacategory | Category that holds all the child categories. e.g. Category:Rivers of England by county. Optional. Use |metacategory2= for a second metacategory
|
| sample_child | Name of a sample child category (without "category:" prefix). Ignored if metacategory is provided. |
| exception | Qualifier to the statement "should hold all entries in the child categories", e.g. exception=apart from seasonal creeks. Optional. |
| type | empty if the parent category is diffused, so not expected to be populated. Optional: defaults to populated. |
| child_scan | PetScan identifier (e.g. 21263054) of a scan that lists all pages in child categories. Used for diffused categories. Optional. |
| child_no_parent | PetScan identifier of a scan that lists pages in child categories that are not in the parent. Used for non-diffused categories. Optional. |
| parent_no_child | PetScan identifier of a scan that lists pages in the parent category that are not in any child category. Used for non-diffused categories. Optional |
| General information | |
| geogroup | If non-blank, includes a {{GeoGroup}} box that lists all coordinates in child pages. Optional. |
| title | Not expected if |metacategory= or |sample_child= is specified. Otherwise default Portal:Geography. Optional
|
| notes | (or |other=) Information about the category such as types of page included. Optional.
|
| main | Name of the main article for this category. Optional. |
| commonscat | Name of the corresponding Wikimedia Commons category. For a second category, use |commoncat2=. Optional.
|
| seealso | Name of a related article. For more than one article, use |seealso2= ... |seealso4=. Optional.
|
| catseealso | Name of a related category. For more than one category, use |catseealso2= ... |catseealso6=. Optional.
|
| footer | Text to be placed below the infobox. May be a template such as {{Census-designated places in the United States}}. Optional. |
| TOC | Enter |TOC=y to place an alphabet table of contents below the infobox if the category holds more than 200 entries. Optional.

PetScan queries
[edit]PetScan is a useful maintenance tool held at petscan.wmflabs.org. Sample queries:
| Purpose | Depth | Categories | Combination | Negative categories | Example |
|---|---|---|---|---|---|
| All articles in child categories | 1 | Metacategory holding all child categories | [1] | ||
| Articles in child but not parent | 1 | Metacategory holding all child categories | Union | Parent category|0 | [2] |
| Articles in parent but not in child | 1 | Parent category|0 | Union | Metacategory holding all child categories | [3] |
The vertical bar and 0 after the parent category name overrides Depth=1 and tells PetScan to only list articles in the parent category, and not articles in categories below the parent.
If there is no metacategory holding all child categories, you may have to list the child categories in the query – or create a metacategory and add the child categories to it.
Before and after example
[edit]Before: multiple lines of text and templates
[edit]
 | For convenience, all unincorporated communities in Alabama should be included in this category. This includes all the unincorporated communities that can also be found in the subcategories. |
This category is for named unincorporated communities in the U.S. state of Alabama that lack political existence, whether census-designated places or neighborhoods.
After: integrated template with PetScan links
[edit] | This is a non-diffused parent category for categories in Category:Unincorporated communities in Alabama by county. It should hold all the pages in the county-level categories, and may hold other pages such as lists.
