The MDG DOORS was developed and tested for DOORS 7.x and 8.x.
But we have seen several customers successfully using it with DOORS 9.x.
DOORS NG is currently not supported.
LieberLieber’s Connector solution to work with DOORS is to use Rif or ReqIf Export/Import capabilities with DOORS. We build a specific addin for Enterprise Architect to read and write those files.
You can see a sample Video on Youtube
Those solutions are tailor made for each customer with our toolbox.
For DOORS NG we can build a bespoke Addin that will consume the OSLC data from the IBM backend.
