The discussion in a discussion group creates
contributions in form of questions and completions. A
factual discussion, however, might also include
additional entities to support the argumentation, e.g.
bibliographical information to reference quotations in
a text (or URLs to reference quotations on a web
resource) as well as biographical information to
reference persons who created a quotation. These
additional three entities (together with additional
helper tables e.g. for historisation) have been
sketched already (see VIF Datamodel, Version 1.5.5) but
they have to be integrated into the application yet.
Besides of persistence layer issues the application’s
UI has to be adjusted to allow participants to create
such entities, to modify and to reference them. (major
challenge)
