A6: NESPOS accounts are personal. This is to protect the users. Each user is responsible for his account and any data uploaded. Letting others use your account would be equivalent to letting others publish in your name (again, think of the reputation risks). We will be offering special volume prices for institutions so everyone can have their own personal account.
Q7: What is a via-file?
Essentially, VISICORE archives are simply zip files with a .via extension. So you can easy rename the .via extension into zip, extract the data and work with the TIFF-files The via files contain the actual image or 3d data files and an xml description of the metadata involved. This xml description file is called MANIFEST.xml and specifies data such as unit size and dimensions. In addition, it contains a reference to the actual data files.
