This page is a translation of GlyphWiki:よくある質問@12.
In GlyphWiki, the term glyph is used to indicate an individual kanji character's specific shape. The term font, when used in the context of GlyphWiki, refers to a group of characters (such as the collection of the 7000-odd characters specified in the JIS kanji set) or its TrueType font file. In GlyphWiki, data are managed on a per-glyph basis. If the group namespace is used, a font file containing all the glyphs in that group can be automatically generated.
GlyphWiki is built on the notion that “everybody owns the data”, so in principle it is not possible to simply delete contributions, even your own. Of course, previously submitted data can be examined or recovered by looking up the history of each glyph (for example, if someone were to replace the data of a submitted glyph with “0:0:0:0”, resulting in a blank page). For more information, please consult the GlyphWiki:DeletionPolicy article.
