Why is this different from the previous case?? OK it's good to go back to such examples all we said in the beginning was that [any big map _:s1 <property> <value>] does entail [_:s2 <property> <value>] **************************************** but I must confess that we *don't* have that always in Euler... it is a long story, and I'm not sure I will be able to explain it, but it is important to have a clear decision on that. I assume that, while asserting aaa bbb _:ccc . _:ccc ddd eee . we for sure assert the triple aaa bbb [ ddd eee ] . but *not* the "contents" of the node [ ddd eee ] (this is N3's [ ] and ako "tree") this is btw a case of unasserted triples (just like N3's { } set of triples) this is just to say how things are in our implementation, and it would be quite straightforward to change it and have extra statements like [ ddd eee ] . for all branches of all trees (so efficiency would go down) I'm feeling better now that I have confessed my sins against MT and I beg for some help -- Jos
