Allow namespace mapping

[paulzierep]

In many cases, it is necessary to create unique URIs of individuals. E.g. when there is a constant stream of data, and you cannot be sure, that the mapped URI will be unique.
One possibility to overcome this issue would be to allow the mapped data to be inserted into the namespace, as shown in:

Another possibility would be to allow to add multiple mappings to the same individual. E.g.: two columns.

Hallo. I think your solution is good. But I think it is also possible, use the current version to realize the example you give. Still create namespace: test: http:/www.w3.org/, and create a new column that combines uuid and the column you want to map in your dataset, for example: uuid+Machine, so you have dsfasaf/A in the column, so in this case, if you create a individual, and map with this column, you can have the URIs you want.
So it is possible to play with dataset instead of graph or namespaces.
Let me know if i misunderstood it.
