The History Plugin

The History Plugin is accessed via the "Plugins" menu. It looks like this:

The main panel displays a hierarchy of the available history information. Usually, there will only be one history list visible: "Current session". Some data adapters may be able to show history lists from past saves, but none of the built-in OBO-Edit adapters can do this at present.

Each history list may contain a number of history items. The "Current session" history list will contain the list of edits that have been made since the current ontology was loaded. To see the edits under a history list, click the expansion control to the left of the history list:

Each item directly under the history list represents a user-initiated edit. Note that each edit above ends with the text "(macro)". This means that these user-initiated edits are complex "macro" edits composed of a number of simpler edits. A "macro" edit can be expanded to show the simple edits of which it is composed:

To see details on any edit, left-click the edit to select it. A text box will appear below containing detailed information about the edit:

Sometimes the detailed information panel will contain a term id displayed as an underlined hyperlink. Click the hyperlink to select the term with that id.

Special details are visible when the history list node is selected:

The top of the detail panel shows who created this initial history list and when it was created (this information usually comes from the "saved-by" and "date" tags in an OBO file header).

The center of the panel shows any ontology comments that were loaded with the current ontology. These comments can be modified and saved by clicking the "Save History" button.
