The Limits of SPARQL

After saying so much about what SPARQL can do, we also want to understand what it cannot do. There are two categories for this. On the one hand, SPARQL is obviously missing some technical features, such as support for a geographic coordinates datatype. On the other hand, SPARQL is also limited in the expressivity regarding the graph patterns it can express. This second limitation is more subtle and requires a closer look to understand.
