Yes. Spec-TRACER includes integration to IBM Rational DOORS. This integration allows users to export and import requirements from and to DOORS along with their blocks, attributes, traces, etc. to a neutral format - XRI (an XML format for requirements interchange). The integration also includes a complete change management mechanism that allows detecting changes when importing the requirements into Spec-TRACER or DOORS. This ensures that the data contained in these tools are not overwritten before any import is done.
