I am using SMW 1.5.0 and i want to use Map and SemanticMap extensions with it. Project page says that it support >SMW 1.5.1 Is there any known issues with SMW1.5.0 ?
Topic on Extension talk:Semantic Maps
I recommend either upgrading SMW or using a version of SM < 0.6, such as 0.5.5. 0.6 or later might work with SMW 1.5, but problems are likely to occur.
