In an ideal world, professional historians would serve as the primary designers and procedural authors of these virtual spaces. It would be unrealistic, however, to assume that a historian could master all the technical requirements to construct a virtual reality display alone. This would be like one person designing, contracting, and building a sky-scraper. It would be more realistic to assume that the historian-as the procedural author-would serve as the "architect" of the virtual reality edifice, the one who conceives of and designs the structure that others construct. Unfortunately, it is just as likely that, as with many "historical" films researched by historians but ultimately designed by nonhistorians, historians working with virtual reality are more than likely to play a supporting role as consulting members of a collaborative team directed by nonhistorians.
This idea of a team to reconstruct historical sites is a very good idea but may not be necessary, depending on what software is used. We've seen in class how software like ArcGIS can be used by people without a technical background so it may or may not be necessary to have a team of people with diverse skills, depending on the project that's being worked on.
