Re: Question about framing

Hi Gregg,

thanks for your reply! I didn't know the playground was able to communicate
the frame: cool.
The proposed solution shows even further entries that I don't want to show,
eg. the @lang: en one.

If this is the correct behavior, IIUC the selection algorithm works at the
predicate level
instead of at the triple level (eg. all of the skos:prefLabel is selected,
and not only the triples matching each possible language)...

Can you point me to the framing specification algorithm that selects the
nodes to show?

Thanks++,
R.
