drag and drop images and files (duplicates are avoided transparently).
all revisions are stored.
a link to any revision can be used as an immutable version, including a MD5 signature that covers images and files.
Documents are browsable (headers are links, and return partial documents)
Documents can be represented as data, and that data is browsable
A paged media preview is available.
Math can be included (Latex as per Mathjax)
Items can be either objects, actions, events or documents. The reason for this classification is that each item class has a slightly different handling. The structure of an action is a gantt chart, while the structure of an object is a component hierarchy.
Items can have components
Actions can have duration and order. Actions can be marked as 'done', 'change', 'test'.
Items can have events. Events in KF are of one class: failures (actual or potential).
Failures can have causes and effects. This structure creates an event tree.
Failures can have associated actions.
Failures can have an associated risk (severity and probability, plus detection and controllability that are specific for automotive).
Actions can have an associated risk (normally a risk mitigation effect on the associated failure)
A failure analysis is a report of an item and its components, its failures and risks, and their associated actions, in a 4 column format. The full event trees are represented in this format.
Each item has an associated (possibly empty) failure tree.
Items can have multiple types (not classes). An item inherits failures and actions of all its types
Wiki document structure comparison. An item that is a type of another item is checked againts the structure of it (all headers are required to be present).
A checklist of an item is defined as those actions associated with a type of an item
The following special formats are integrated into the 4-column failure report: FMEA, FMECA, DRBFM and DRBTR. FMEA and FMECA are the same thing, the failure analysis of an item and its components. A DRBFM is the failure analysis of a change. A DRBTR is a failure analysis of a test.
