===== Why BIM-and =====

BIM projects contain a lot of data. Geometry data describing the 3D model and alphanumeric data for all the properties of all the construction elements.

**BIM-and** is designed to focus on these alphanumeric data and allows to
  * specify access control, on a per value level
  * provides a historical view to the stored data
  * access alphanumeric data by selecting elements in the 3D model
  * filter elements by alphanumeric values
  * store applied filters for later use
  * ...

===== How does BIM-and work =====

**BIM-and** uses [[https://de.wikipedia.org/wiki/Industry_Foundation_Classes|IFC]] files that have been uploaded to a [[http://bimserver.org/|bimserver]], imports their alphanumeric data into a separate Database, assigns user [[wiki:permissions]] to these data and links them to the original [[wiki:bimserver]] 3D model.

This approach brings the following advantages:
  * limited number of users that are allowed to access the [[wiki:bimserver]] directly
  * fine grained user [[wiki:permissions]] - down to each single value - in a UNIX like ''rwx'' fashion
  * [[wiki:users]] belong to [[wiki:users|groups]]
  * [[wiki:permissions]] for [[wiki:users|owners]], [[wiki:users|groups]] and [[wiki:users|'others']]
  * store modifications of data and provide access to [[wiki:historic]] data
  * export selected data to XLSX files
