Example of Cognitive OpenLS

Here is a short example of how wayfinding situations can be specified using Cognitive OpenLS.

In the depicted situation, a wayfinder has to turn right into Berckstrasse coming from Horner Heerstrasse. The intersection consists of four branches and there is a church present.

The following XML-code illustrates how this situation is encoded in Cognitive OpenLS. For further details please refer to our publications.
