The OCFA treegraph API is a more advanced API for the [[Open Computer Forensics Architecture]]. The basic [[OcfaLib API]] allows for the fast and simple creation of simple dissector and extractor modules for OCFA, but has some limitations.
 
To overcome these limitations, the 2.2 version of OCFA re-vectored and promoted an API that was previously used internally by th OCFA library to an API available to module builders.
 
The OCFA treegraph API defines an interface that a loadable library must implement in order to be usable as an advanced dissector module bu the Open Computer Forensics Architecture.
 
Basically it defines an interface  'TreeGraphNode' that a treegraph module will need to derive one or many classes from. A TreeGraphNode can contain data, meta-data and sub node's that are also TreeGraphNode implementations.
 
The data interface of the TreeGraphNode also allows treegraph modules that are [[CarvFs]] aware, to return a carvpath as so called soft linkable path'. Doing so allows OCFA to use substantially less storage resources.
 
  
An example of a treegraph module for OCFA is included in the 2.2 release of OCFA. This example is the OCFA mmls module.
 
The ocfa mmls module reproduces the functionality of the [[sleuthkit]] mmls tool. It does this using the OCFA treegraph library,
 
the [[LibCarvPath]] library, and the [[sleuthkit]] library.
