Why, is the page dynamically reconfigured for other people? I'm not saying
"first" in some mushy philosophical sense, I'm talking about the first
attribute that appears in the structured-data section of the page, right
under the headings "Attributes" and "Values".

What? Whatever: you've got plenty of other entities, so surely you could
pick one where the errors aren't as prominent. Here, for example, is the
next one I tried:

There are some dubious bits to this, too (she only "composed" one song?** a
person is "subsequent work" of a song?***), but at least this is a page
about a person that appears to be about a single person. Same technology,
better "demo".

In due course you will understand my point.


Understood your points the first hundred times you stated them. Any time
you'd like to take a turn understanding mine, feel free.


> You characterization is 100% inaccurate.


In the context of your insistence on the subjectivity of everything, I
assume this is intended as a joke. Funnier without the typo.
