Tags aid in searching and browsing images.
Tags are being introduced to replace the current fledgling Category (Primary Geographical Category) system. They also introduce a very simple categorization system in the form of "Geographical Context" tags.
- The number of categories available during the submission process will be reduced to around 45.
- There is no 'Other' category, you must choose one (or more) from the list.
- The aim of the Geographical Context section is to provide high level categorization to tags/images.
- Add further Tags by simply typing as required in the 'Tagging box'.
- Tags are free-form, but intelligent suggestions will be provided to speed up the process.
- It is not compulsory to add any Tags.
- Please add as many Tags as you need. Tags will help other people find your photo.

A new submission requires at least one Geographical Context tag, and we well be endeavouring to automatically add the tag(s) to a bulk of the photo back catalogue.
- only a basic browsing interface)
- categories have not been batch converted yet
- the auto suggestions for adding new tags is very basic, more to be added
- process to be streamlined, so don't have to go to edit page etc to add tags
- moderators have no special privileges to add, and in particular remove, tags from images from everyone's images
- tags are not tracked in the suggestion system (undecided if they should be yet...)
- Can use any normal characters (a-z A-Z 0-9 etc), brackets "(" ")", and the minus/dash "-" sign.
- Spaces/underscores are used as word separators.
- Do not use colon ":", semicolon ";", comma "," and pipe "|" - they will be removed.
- Can currently use other characters, but their use is not recommended.
Only the photo contributor can add a public tag to their images. But if multiple people define the same private tag for a photo its eligible to be promoted to a public tag. [the exact details to be worked out]
Private tags, are a useful way to mark images so you can find them again in the future. For example could have a 'favourite' tag (call it what you like!), to find your favourite images.

Note: The terms and cluster databases are built using a bulk offline process (using resources donated by geograph members) - so the most recent images don't likely have any terms/clusters yet. Now we have a more high profile use for these databases it should give us an incentive to keep them more current.
name-space for tags. In many places tags may be shown WITHOUT the prefix.
Anyone can create a prefix, but there are certain known prefixes that have special meanings.
The format is prefix:tag, (ie a colon separates the prefix and tag) for example bucket:transport is a tag 'transport' in the 'bucket' name-space.
There are the following reserved prefixes...
- top: A tag added from the 'Geographical Context' list, (the prefix top is used because we have called them Top Level Categories) ***
- bucket: to be used used for the special bucket project [more details to be added] ***
- category: automatically used on tags created from the image category
- cluster: automatically used on tags created from automatic clusters
- term: automatically used on tags created by term extraction
- geographical feature: being used to build a collection of geographical galleries, more info ***
Can also use prefixes to annotate what you tagging, examples
- lake:Llyn Celyn
- mountain:Ben Nevis
Or classify tags by type
- man made:Reservoir
[more details to be added - this is still open to discussion]
*** Note: tags using these special prefixes may be made Public - even for tags marked Private.
Can enter tags in the keywords box. Eg [train] to search for images tagged with 'train'. Also works with Prefixes, eg [place:London] and spaces [River Themes].
If just want to search 'in' the tags on the image, use tags: format. tags:London - looks for London anywhere in tags - so matches "London Bridge", and "London Eye" for example.
Add a new tag, by entering a tag in the box, and click Add. (can also just press enter)
* Can enter multiple tags at once, separated by , or ; (comma or semicolon).
On your own images can choose between making the tag Public (green) or Private (red), click the tag itself to toggle the colour.
Can remove a tag by clicking the X against a tag. General (yellow) tags are public tags added by the image owner and cannot be removed by other people.
In many cases suggestions for tags will be displayed below the Add box, simply click a 'Use' to enable the tag.
Note: the changes you make are saved to the server immediately. Changes are not tracked in Suggestions/Tickets.
