nuqjatlh, cha’DIch (What does it mean, too? / Sekunde mal, wat soll’n dit heißen?)

Unter „semantischem Markup“ verstehen viele, die jeweils passenden HTML-Elemente einzusetzen. Diese beschreiben aber die Struktur, nicht den Inhalt einer Webseite.
Damit „verstehen“ Maschinen (bspw. Suchmaschinen) noch nicht, worum es auf der Seite geht. Dem kann man mit microformats, microdata, RDFa, Schema.org nachhelfen. Davon profitieren nicht nur Suchmaschinen; es werden auch andere Anwendungen gezeigt, die den Nutzern zugute kommen.
Achtung: Der Vortrag kann Spuren von klingonischen Flüchen enthalten.

7. Tonight we want to add our voices to the thousands
   of Americans who are protesting at airports around
   the country the Muslim Ban and the detention of
   foreign nationals and refugees. America is a nation
   of immigrants and we find this anti-democratic and
   fundamentally un-American.

   AMERICAN LAND
   Written by Bruce Springsteen
   The McNicholas, the Posalskis, the Smiths, Zerillis, too
   The Blacks, the Irish, Italians, the Germans and the Jews
   Come across the water a thousand miles from home
   With nothing in their bellies but the fire down below
   They died building the railroads worked to bones and skin
   They died in the fields and factories names scattered in the wind
   They died to get here a hundred years ago they’re still dying now
   The hands that built the country we’re always trying to keep out
