Federated Wiki lets you fork the story and journal of a remote site by hitting the "Flag" button in the journal at the end of a page, and now you have a copy in your local wiki. What if you want to update more selectively to keep your local copy up to date with its source, without losing local changes?
"Drag and Drop Journal" is one approach.
Federated Wiki's web client supports pulling the updates from a remote page via dragging its journal widget on the journal widget of a local page to create a proposed merger as a ghost page.
Can you drag and drop individual items from one page's story to another to bring changes into your local copy of a twin page? This is a way you might refactor a single page or a number of local pages. But you can't drag and drop items from two pages that share the same title.
This is disallowed because there are cases where dragging a paragraph/item from one page to another which has the same title can be accidentally destructive.
You can work around the disallowed move using an intermediary page with a different title for dragging items in, then out.
Or you can drag and drop the journal and see if you like the results, recovering any lost items if needed.
Delight and Outrage is a sample twin page between sites on Ward's farm "dojo.fed.wiki", in this case jeff.dojo.fed.wiki, and Viki's farm "ubu.wiki", in that case failbetter.ubu.wiki, and now this wiki, recurse.pixiereport.com .
