Create aliases to functions used in templates
That could help users if several ways are possible to get the same information.
For instance, syssample.get("source_sentence")
could be syssample.data["source_sentence"]
or syssample.get_attribute("source_sentence")
.
If we can make it possible that all ways work, each developper could just use the way she/he remembers.
