"Reasoning" capability can be added to any conventional database via the use of views, and sometimes custom indexes. The real problem is that it's computationally expensive for non-trivial cases.

I hardly see how you can define in a RDBMS that a resource that both have an engine and four wheels should be seen as a car. Without going into a nightmare of unbearable SQL...

The SQL for describing "resources that contain other resources" gets a bit unidiomatic, but defining a query for those that have e.g. an engine and four wheels is quite easy. Then you can add that as a custom view, so that your inferred data is in turn available and queryable on an equal basis with raw input to the knowledge base.

Sigh

When the phrase "The King is dead, long life the King" is used, the two kings are different people; the one that just passed and the one that replaced him. If the King is replaced by a Queen then the phrase is "The King is dead, long live the Queen". This is not some life after death thing. You aren't saying the King will live on in the hearts and minds of the people, you're stating your support for the successor.

The new king of the Semantic Web is obviously Neo4J.

Oh, I would like to see a look on your face when just in about 100-200 years from now it will be mature enough for a "web scale".

Just 200 years around the corner.

Maybe 300. But no longer, I'm confident! Do you want to be left out in a couple centuries? You better get on the train now.

Sure. But maintaining the coherence between your business data model definitions and their implementation in the RDBMS can quickly become a massive headache, don't you think?

Probably the oldest gem I can remember, harvested from from a more senior mentor type, was the quip “It takes 3 times to get it right. And that’s an average. Get failing.”

Now, I’m that older guy. I still think this holds.

Semweb people got burned out by the stress of making new standards which means that standards haven't been updated. We've needed a SPARQL 2 for a long time but we're never going to get it. One thing I find interesting is that description logics (OWL) seem to have stayed a backwater in a time when progress in SAT and SMT solvers has been explosive.

True. But and also, web standards seem to have mostly been abandoned/died beyond just semantic web. I am not sure how to explain it, but there was a golden age of making inter-operable higher-level data and protocol standards, and... it's over. There much less standards-making going on. It's not just SPARQL that could use a new version, but has no standards-making activity going on.

I can't totally explain it, and would love to read someone who thinks they can.

That github was created 2 days ago, wasn't this article discussed elsewhere someplace? It looks very recognizable. Was it on a blog or something and just made a new home in github or was it some other similar article I may be thinking about.

I wrote it from scratch 2 days ago.

nice, maybe I'm thinking of

semantic web and dead I think paired up a few places previously. Thanks for cataloging all the subject matter in github. I have a background interest in this subject that's been kicked around a bit through the years.

Always this was a contagious but meaningless gimmick. Thanks for the explanation.
