It is doubtless that semantic networks are a valuable tool in natural language processing and in reasoning about actions. However, having semantic networks and plain text as interleaved alternative streams of the same content, which is what the demonstration shows, seems to be too vulnerable and

We have two options for having both human-readable and machine-readable information in a document: write the structure and generate the text or write the text and recover the structure. At the very least, if you insist on having both, there must be a mechanism to verify that they are consistent.

This amounts to saying that URLs take precedence over CURIEs and CURIEs can be enclosed in brackets in case of any ambiguity. This sounds ridiculous given the weight you put on avoiding ambiguities and name clashes. Since the author does not control the URL scheme registration process, he can
