17. Using basic section 7 -
“relation”

18. Using basic section 7 -
“relation”
describes relations between different learning
objects
not “metadata”

19. Using basic section 7 -
“relation”
describes relations between different learning
objects
IS PART OF
not “metadata”

20. Using basic section 7 -
“relation”
describes relations between different learning
objects
IS PART OF
not “metadata”
would lead to combinatorial explosion of
relationships

31. Resolve with Identifier Service
cfr. HTTP “content negotiation” –
mechanism.
e.g. “Accept-Language: fr”
