V5 For a list of metatags, see [[tag_group:metatags]].

Metatags are tags that describe metadata. Metadata is data that conveys information about other data.

So in other words, metatags are tags that convey extra information about an image or video file [b]but not the content of the image or video itself.[/b]

This includes things like year of production, provenance (was it a commission, drawthread request, gift art, etc.?), file size, modifications, edits, translations, source, compression, etc.

[b]Example differences between general tags and metadata tags[/b]
In each example, notice how the metadata tags are describing something about the general content tags.

[b]Content:[/b] [[text]], [[dialogue]], [[english_text]], [[japanese_text]], [[spanish_text]]
[b]Metadata:[/b] [[translated]], [[hard_translated]], [[alternate_language]]

[b]Content:[/b] [[censored]], [[censor_bar]], [[mosaic_censor]], [[novelty_censor]]
[b]Metadata:[/b] [[decensored]]

[b]Content:[/b] [[color]], [[pastel_colors]], [[muted_color]], [[colorful]], [[monochrome]], [[greyscale]]
[b]Metadata:[/b] [[colorized]]

[b]General tags often mistaken for Metadata[/b]
*_background
[[signature]] / [[artist_name]]
[[dated]]
[[watermark]]
[[censor_bar]]

The basic rule of thumb is that anything you can see in an image is probably not be metadata because if you can see it, then it is probably part of the content. Here are some examples of metadata that still has a visual component.

Image artifacts like [[jpeg_artifacts]] or [[scan_artifacts]] are visible, but they are still metadata because they are not intentional parts of the composition or content, they are byproducts of compression algorithms or scanning methods. Tags like [[animated]], [[slideshow]], [[animatic]], [[music_video]], [[looping_animation]] are describing how a sequence of images is perceived, so they are also metadata.

V4 Metatags are tags that convey information about an image or video file [b]but not the content of the image or video.[/b]

The classic rule of thumb is that anything that is visible in the image is not metadata, but this does not apply to visual artifacts since they are not an intentional part of the content, but rather the result of compression algorithms applied to a finished image.

That rule of thumb also does not apply to modifications / [[third-party_edit]]s. These tags are describing how an original composition was modified to look the way it does now e.g., an image containing [[english_text]] is not necessarily [[hard_translated]], and a fully [[color]]ed image was not necessarily [[colorized]].
