<h1 id={'intro'}>Introduction</h1>
<p>
Hivemind is a free tool that lets you create mind maps in your
browser. It supports time-travel (through the change history of the
mind map), tagging specific time points (
<Badge color="secondary">Planned</Badge>) and collaborative editing (
<Badge color="secondary">Planned</Badge>).
</p>
<h1 id={'at-a-glance'}>At a Glance</h1>
<p>
Each mind map is modelled as a tree, ie. it has a single root node,
and all other nodes are descendants of this root node through a single
hierarchy. There are no cases of multiple parents, cycles, loops
(self-joining edges), parallel edges or orphaned nodes.
</p>

<CardTitle tag="h5">An example mind map</CardTitle>
<CardSubtitle tag="h6" className="mb-2 text-muted">
Tree structure with a single root node.
</CardSubtitle>
<CardText>
This tree is 3 levels deep. Each node can have one or more
children, but exactly one parent (except the root node, which
has none). The timeline at the bottom shows at what points this
mind map was modified.
</CardText>
</CardBody>
</Card>
</CollapsibleExample>
<p>
Each node in the mindmap is a container for information. There is a
title, a summary and a content field. This node is connected to
exactly one parent by an edge (except when it is the root node), and
can optionally have one or mode child nodes. The edges themselves do
not carry any information at present, other than which nodes they
connect.

</CollapsibleExample>
<h2 id={'key-points'}>Key Points</h2>
<p>
Every write operation that is performed on a node
(create/update/delete) is recorded permanently in a time-travelling
database, allowing for point-in-time lookups of any historic version
of a single node or the graph as a whole.
</p>
<ol>
<li>
The root node is special - it cannot be deleted, and is the only
node without a parent.
</li>
<li className={'text-danger'}>
Whenever a node is deleted, the entire subtree under it is also
deleted in order to ensure there are no orphaned nodes.
</li>
<li>
Only users with edit or admin access can perform write operations on
the tree.
</li>
<li>
<Badge color="secondary">Planned</Badge> A user with admin access
can additionally share the mindmap with other users (by
granting/revoking read/write/admin access) or make it publicly
(in)visible (read-only).
</li>
<li>
<Badge color="secondary">Planned</Badge> Only an admin user can
delete a mind map.
</li>
<li className={'text-danger'}>
Access control is <strong>NOT</strong> modelled temporally, ie. if
your access to a mind map is revoked, you lose access to ALL its
history, not just from the time of revocation. Conversely, if you
are granted access to a mind map, you gain access to its{' '}
<strong>ENTIRE</strong> history, not just from now onwards.

<h2 id={'create-child-node'}>Creating a (child) node</h2>
<p>
Each node (except the root node) is a child of exactly one other node.
While the root node is automatically created for you when you create
the mind map, every other node must be created as a descendant of the
root node by accessing a context menu within the mind map canvas (the
black area). This context menu is available on all nodes, but its
contents could vary depending on a number of factors. The ‘create
child’ option is available, provided:
</p>
<ol>
<li>The user has ‘admin’ or ‘write’ access to the mind map, and</li>
<li>
The mind map is being viewed in ‘write’ mode (i.e., not in ‘lookback
mode’ - to be discussed later).

<h2 id={'hide-node'}>Hiding a node</h2>
<p>
Each node (except the root node) has an option to be hidden from
display on the canvas. This can be useful to temporarily remove
clutter when a large number of nodes are on display. Upon hiding, the
entire sub-tree under the node is also hidden. To indicate that a node
was hidden, its parent is marked in a grey/black shaded background.
The hidden node (and all its descendants) can be revealed using a menu
option under its parent.
</p>
<CollapsibleExample>
<HideCarousel />
</CollapsibleExample>
<ul>
<li>Click on the node which you wish to hide.</li>
<li>
Select the ‘<EyeOff /> Hide’ option.
</li>
<li>
Hides the entire sub-tree under this node (as well as the node
itself).
</li>
<li>Shades the parent to indicate hidden children.</li>
</ul>
<h2 id={'reveal-node'}>Revealing (Un-hiding) a node (sub-tree)</h2>
<p>
A hidden node (and its descendants) is indicated by a shaded
background on its parent. To reveal its sub-tree and render them back
onto the canvas, a menu option is added to the parent (only for
parents with hidden children). Clicking on this reveals (un-hides) the{' '}
<strong>entire sub-tree under the parent</strong>.
</p>
<CollapsibleExample>
<RevealCarousel />
</CollapsibleExample>
<ul>
<li>Click on the (shaded) node whose children you wish to reveal.</li>
<li>
Select the ‘<Eye /><ArrowDownRight /> Reveal’ option.
</li>
<li>
Reveals the <strong>entire sub-tree under this node</strong>.
</li>
<li>Un-shades the node to indicate no hidden children.</li>
</ul>
<h2 id={'time-travel'}>Time travel</h2>
<p>
Hivemind can <strong>time-travel</strong>. What this means is, as you
keep changing the mindmap through create/edit/delete operations,
Hivemind keeps track of all these changes and retains a history of all
the revisions of the mind map as a whole. This gives users of Hivemind
the unique ability to rewind back to any point in time through the
history of the mind map, and view it as it was at that time. This is
achieved either by using the timeline component (below the canvas) or
the playback buttons (in the menu bar above the canvas). See the image
below.
</p>
<CollapsibleExample>
<Card className={'mb-4'}>
<CardImg
top
width="100%"
src="/img/help/Screenshot_2021-03-28-10 Hivemind.png"
alt="Time Travel Controls"
/>
<CardBody>
<CardTitle tag="h5">Time Travel</CardTitle>
<CardSubtitle tag="h6" className="mb-2 text-muted">
Use the playback buttons or the timeline.
</CardSubtitle>
<CardText>
Travel back/forth through the history of changes to the mind
map, and view it as it was at any point in time through its
lifecycle.
</CardText>
</CardBody>
</Card>
</CollapsibleExample>
<p>
Whenever the user travels through time to look back at a historical
version of the mind map, it is said to be in{' '}
<strong>‘lookback mode’</strong>, and all modifications are disabled
(since its history is treated as immutable). This is indicated in
three ways:
</p>
<ol>
<li>
A <code>timestamp</code> query parameter in the URL, which also
serves as a permalink to this point-in-time version of the mind map,
</li>
<li>
A button at the top right of the menu bar, which shows a{' '}
<span className={'text-secondary'}>
<Lock />
</span>{' '}
symbol (otherwise showing a{' '}
<span className={'text-danger'}>
<Unlock />
</span>{' '}
symbol when in ‘write mode’),
</li>
<li>
A grey border around the canvas (which is otherwise red in ‘write
mode’).
</li>
</ol>
<p>
<strong>
While the mind map is in ‘lookback mode’, it cannot be edited.
</strong>
</p>
<h3 id={'timeline'}>Using the Timeline</h3>
<p>
The timeline is the component displayed at the bottom of the mind map
canvas, that shows a time series of write events that took place on
the mind map, in chronological order. It has the following properties:
</p>
<ol>
<li>
The timeline can zoom in and out. This is manually achieved by
scrolling while the cursor is on the timeline (or using pinch zoom
on a touchscreen).
</li>
<li>
When fully zoomed out, the timeline fits all events of the mind map.
It cannot be zoomed out beyond the boundaries defined by the first
and the last events of the mind map.
</li>
<li>When fully zoomed in, it has a resolution of 1 minute.</li>
<li>
Events are color-coded to depict their type. A ‘create’ event is{' '}
<span className={'text-success'}>green</span>, an ‘update’ event is{' '}
<span className={'text-primary'}>blue</span> and a ‘delete’ event is{' '}
<span className={'text-danger'}>red</span>.
</li>
<li>
When two or more events get too close together on the timeline to be
clearly rendered (ie. they start overlapping), they are clubbed
together in a ‘cluster’, with a number showing the number of events
in that cluster.
</li>
<li>
A cluster can be expanded to fill the timeline by double-clicking on
it.
</li>
<li>
Double-clicking an empty portion of the timeline will cause it to
zoom out fully.
</li>
</ol>
<p>
Open the example below for a step-by-step guide how to use the
timeline.
</p>
<p>
<strong>
Any jump triggered on the timeline automatically puts the mind map
in ‘lookback mode’.
</strong>
It can be put back into ‘write mode’ by clicking on the{' '}
<Button outline color="secondary" size={'sm'}>
<Lock />
</Button>{' '}
button at the top right in the menu bar.

<h3 id={'playback'}>Using the Playback Buttons</h3>
<p>
The playback buttons at the top menu bar should be fairly easy to
understand and use. They look and work similar to an audio player -
only that in this case, the buttons are used to jump between events on
the timeline, rather than between items in a playlist.
</p>
<ol>
<li>
The{' '}
<Button outline color="secondary" size={'sm'}>
<SkipBack />
</Button>{' '}
button takes you directly to the first event of the timeline.
</li>
<li>
The{' '}
<Button outline color="secondary" size={'sm'}>
<Rewind />
</Button>{' '}
button takes you to the previous event from the current event on the
timeline. If you are currently in ‘write mode’ then this takes you
to the last event.
</li>
<li>
The{' '}
<Button outline color="secondary" size={'sm'}>
<FastForward />
</Button>{' '}
button takes you to the next event from the current event on the
timeline. If you are currently in ‘write mode’ then this takes you
to the last event.
</li>
<li>
The{' '}
<Button outline color="secondary" size={'sm'}>
<SkipForward />
</Button>{' '}
button takes you directly to the last event of the timeline.
</li>
</ol>
<p>
<strong>
Any action on the playback buttons automatically puts the mind map
in ‘lookback mode’.
</strong>
It can be put back into ‘write mode’ by clicking on the{' '}
<Button outline color="secondary" size={'sm'}>
<Lock />
</Button>{' '}
button at the top right in the menu bar.

</ul>
<h2 id={'rename'}>Renaming a mind map</h2>
<p>
The mind map can be renamed when in ‘write mode’. This is true when:
</p>
<ol>
<li>The user has ‘admin’ or ‘write’ access to the mind map, and</li>
<li>
The mind map is being viewed in ‘write’ mode (i.e., not in ‘lookback
mode’ - as discussed earlier).
</li>
</ol>

</li>
<li>This button can be found in the menu bar.</li>
<li>Modify the name as required and hit ⏎ (<Enter>).</li>
</ul>
<h2 id={'fit'}>Fit on canvas</h2>
<p>
If the mind map does not optimally fit in the canvas, either because
you played around with the canvas zoom or moved a few nodes around, or
just hid/revealed a bunch of nodes, you can force them to optimally
fit by clicking on the{' '}
<Button outline color="secondary" size={'sm'}>
<Maximize />
</Button>{' '}
button in the top menu bar.
</p>

</CollapsibleExample>
<h2 id={'show-all'}>Show All</h2>
<p>
If several sub-trees were hidden on the canvas, it can get tedious to
reveal them all by navigating to their parents one-by-one. For such
cases a quick shortcut is to click on the{' '}
<Button outline color="secondary" size={'sm'}>
<Eye />
</Button>{' '}
button in the top menu bar. This causes the canvas to immediately
reveal all hidden sub-trees and also re-run the layout if necessary.
