The scribbling is transferred to http accessible DB and then added to the BIM server in order to be used by other stakeholders (c.f. Fig 11). From the AR client adapter, the annotation is retransferred to the service backbone. Thereby, the tracked position of the annotation is used to establish a geolocated reference within the BIM model. The annotation can also be used by different stakeholders that are working on the building with the BIM data.
