one of the truths about semantic web & it's so-called "failure" that a lot of people don't have any grasp on is that the tooling was really really really offputting for a long time. the people building RDF engines & libraries were not web application developers, had no experience with modern web applications.

it took ages for them to start adopting CommonJS or EcmaScript Modules, modern packaging like npm. these factions werent in touch with what developers were trying to do, how they dealt with data. the semantic web failed to be of service to the mainstream web development world, failed to build tools that fit in.

i still think the semantic web is happening. around 2018 things started getting better, modern looking libraries started emerging. there's still a lot of spiritual clash, it's still not clear how to make a web application powered by it's own semantic data on the page, but tools & techniques like this start to draw us closer, start to weave the web tighter & open possibility spaces.
