| 28 | | Changesets exists for every of your "edit". They simply group data creations, modifications and deletions - with additional properties {{{comment}}}, {{{created_by}}}, {{{imagery_used}}} [osmwiki:Proposed_features/changeset_tags and several others] (this information stored as simple tags). Similar to other wiki software, one changeset can affect one object (a single character edit in the text), but may contain big changes (removals of paragraphs, partial or complete rewrite of the text) with the only difference that geo information is edited instead of text. Investigating history of one character is equally hard to comparing text at given point in time. Since [osmwiki:Planet.osm complete "text" in OSM is 30-600GB big] therefore users speak of history within several changesets and not about complete history every time. |
