Is schema.org still relevant?

Hi Tim,

A long time ago (around 2010), when I went to fully customize a OSC 2.2 (oh ! this is in fact the same version number of litecart here...sign of fate ?), I had to modify the html of pages to include: [b]FB open Graph : [/b]which seems to be done here in litecart, by default. 

But I remember another one, that in fact, at this time, I did not exactly got the true benefits after applying them (at least it did not change anything in my Google's places) which is [b]schema.org[/b]

[b]Is this in 2019 something that should [/b][b]also be applied ?[/b]
Maybe it's quite obsolete and/or replaced by something else ?.

Quite the opposite. Schema is very much something Google loves taking a bite of.

So it should be applied, right ?
Will it be in a future version (maybe a mod) ?

OH OKAYYYYY...:
I got it it's already done and I did not know.
I just noticed it because it is implemented another way (in a form of .js) that I used to know (html attributes) 
<script type="application/ld+json">{"@context":"http://schema.org/"....
So...this topic is closed....
