I'm working on language ressources and graphs and in my opinion, RDF is so flawed you shouldn't even bother with it. I will address the topic during a conference in June (email me -- info in my profile -- for follow up or to get my articles if you're interested by the topic). JSON-LD is trying to make RDF sexier (more exactly said, RDF try to pimp itself by using JSON-LD) but as it is just RDF with a new serializatio…

I don't know what MP means, but if you publish an article I'd be interested in checking it out.

I thought hacker news had private messages but no (and well MP is French, so my mistake it should have been PM), so send me a mail at the address found in my profile https://news.ycombinator.com/user?id=titanix2 so I can contact you back.

I'd also be interested in the article if you publish one, but I don't see any email in your profile. I believe only the `about` section is displayed publicly.

Ah yes, the email field is not displayed. Fixed.

Is there a reasonable alternative? I've worked with RDF and LD and can agree with most of your points but would like to see if there is something better on the horizon.

Currently no. I am concerned with making dictionaries better (especially mobile applications), so I don't have a general purpose solution but I propose something for that use case. I basically started from scratch and came up with a very simple type system which aggregates a few values (name, id, type, ...). This type system is not hierarchical so no inheritance; you could implement it with a few classes in a OO lang…

There are plenty of ontologies already defined that someone could use. I'm currently involved in work to map STEP [1] onto RDF/OWL/SKOS and it seems to be working out well.

I know that some of my collegues are using JSON-LD as the interchange format for this kind of thing.

Prolog + Datalog? Prolog should even parse JSON without 3rd party libs with minimal fuss using just its integrated parser construction facilities (eg. the `op` built-in predicate).

Prolog won't come with reasoners for the description logic profiles supported by OWL 2 (EL, RL), but can be used to implement such reasoners if needed.

It totally depends on what you are doing. You need to take in account if using an ontology will solve any problem at hand. Also you may have an ontological system not build in RDF. At least in what I'm doing, RDF is creating more problems than it solves. Finally there is all the political layer that may go against publishing your data in an open and (web) accessible format and then you need another solution anyway.

Try leading with an explanation of why developers should care about JSON-LD. Its value is not obvious to me. According to the Wikipedia article [0] this is used by Google Knowledge Graph, but there's no other examples. Are there open source RDF processors? What are they used for? Previously I've used json-schema for documenting, validating, and testing a REST API. The tooling wasn't very good, but it worked alright.…

ActivityPub [1], (Mastodon [2]), also use JSON-LD.

All this sort of sounds like topic maps, though they never gained much of attention and very few people know of or remember them, and beside Java there are virtually no libraries or tooling for them.
