The project in question is a plugin for the Eclipse IDE. They went with an Eclipse license. If this project is not specifically "for people who inhabit that community," then who is it for?

I think Oracle does. My impression is that PostgreSQL sort-of "invented" JSON support in the db, then Oracle (and probably others) added JSON support with a different syntax, and then Oracle got their version defined into the SQL standard. I'm half-guessing here, but it's based on what I've gleaned from Markus Winand's [0] excellent compatibility tables in his slides [1].

Java Is Still Free 8 years ago

Or it could just be a problem with people over-complicating things. User bradleyjg does a great job of summarizing the scheme in the post just above yours -- it's amazing how much virtual ink has gone into discussing this when things really are that simple.

One of the big things to come out of the semantic web was RFD-A (embedding semantics in unstructured web pages) and similar technologies (microformats, JSON-LD, schema.org). It's what lets Google show product reviews and rankings in search results, and lets shopping aggregator sites show things like price comparisons from other websites. While it's probably not as widespread as its boosters from a decade ago hoped it would be, it did lead to some helpful technologies that are in widespread use now.

I wonder if Facebook won't someday be forced to publish its social graph data in FOAF format the same way Microsoft was forced to publish its Office document specs as part of an anti-trust decision.

Speaking of Facebook, the OpenGraph tags are another example of widely-used semantic data on the web, maybe the most widely-used, since all kinds of sites pull in page summaries, images, and other data from those tags. So while Facebook doesn't make social network data available, it did popularize a format for sharing other types of data (about companies, articles, websites, etc.).

No. Java's "write once, run anywhere" promise is that you would not have to re-compile your source code to target different architectures like you do with C or C++. Docker's promise is that you don't have to rely on external things like databases, filesystem details, and other things _outside your program_ being in place across environments. Same idea, different levels of abstraction.
