LINKODER is a tool to analyse coded segments and their linkographs of design protocols. It's based on FBS design ontology and FBS protocol coding scheme. This coding scheme is a principled ontological method that is applicable to design protocols independent of their domains and subjects. The universality of FBS coding scheme made it possible to develop  LINKODER as a standardised tool which is usable in different research scenarios.

In the field of design cognition, different measurement methods have been developed to analyse a coded design protocol. Dynamic entropy, first and second order Markov models, first passage time and dynamic models of issues and processes are among these analysis methods. LINKODER carries out these measurements and generates the responding models for each of them. The interactive nature of this tool makes the time consuming task of analysing design protocols easier and adds an explorative side into quantitative analysis of design protocols.
