The Boehringer Mannheim Poster is famous. Next to it being available as a very esthetic poster for your wall, it currently is also available as digital scanned images. The latter is very handy to use parts of this poster for educational purposes. Unfortunatly I can't find a license agreement on the hosting website.
If my understanding is correct, then when no license is stipulated the use of the data is prohibited. So am I allowed to use the poster as is for education, which would include that students would use the knowledge to do proper pathway analyses.
As Andra Waagmeester is in the Netherlands, fair use rights might not apply. For him he may normally use them for teaching if the contents fall within the 'lesson' plan. If he is using them for wiki pathways editing, all bets are off as he must then also consider 'databank recht' a dutch/belgian concept.
