Is it realistic to use ReqIF Studio when multiple people are editing a requirements set simultaneously? It is possible to include multiple ReqIF models in a project and link entities between those models. If I have say two models in a project, could two people each edit a model, then one of them merge their changes into the project in which the other model was changed. If this is possible presumably it would be necessary to guarantee that any links that existed pre-editing are maintained.
Concerning linking entities in different models of a project, what are the constraints? Each model (as far as I understand) has its own set of SpecTypes, Datatypes and Presentations. For the Spec Relations that cross two models in a project, does it matter which model the Spec Relation is configured, or is it needed in both?
