RDF is a shitty data model. It doesn’t have native support for lists. LISTS for fuck’s sake! The key data structure that’s used by almost every programmer on this planet and RDF starts out by giving developers a big fat middle finger in that area. Blank nodes are an abomination that we need, but they are applied inconsistently in the RDF data model (you can use them in some places, but not others). When we started with JSON-LD, RDF didn’t have native graph support either. For all the “RDF data model is elegant” arguments we’ve seen over the past decade, there are just as many reasons to kick it to the curb. This is exactly what we did when we created JSON-LD, and that really pissed off a number of people that had been working on RDF for over a decade.
