What's happening with Semantic Web? Have people just given up? I'm talking about RDF, RIF, OWL, etc.

Are people using these standards to build web apps in a sort of model-driven way? Where are the implementations?
Ontologies seem to be another word for "reusable, importable class hierarchy of entities and relations";
kbpedia (mkbergman.com)
seems to lead in that space; but I'm not seeing export/import (with RIF) into rule engines and web app development frameworks.
Bergman calls them "Ontology-Driven Apps": mkbergman.com/2267/combining…
OMG calls it "Model Driven Architecture": worldscientific.com/doi/abs/10.114…

They are keepers of the light for the UML tradition, which begat SBVR, BPMN, DMN, OCL, etc etc.

@BR3NDA @verbman @mattwadd @jamesondempsey @piawaugh @danielselman @craigaatkinson @RoundTableLaw @PolicyLabAU @digital_nsw @OpenFisca no … the tests come out of our Haskell rewrite, but the code that passes the tests is the latest OpenFisca Python version, so this is as close to ams-length as two implementations can get. These tests do find some failure cases for the 2018 numbers, so I hope that's helpful…
@BR3NDA @verbman @mattwadd @jamesondempsey @piawaugh @danielselman @craigaatkinson @RoundTableLaw @PolicyLabAU @digital_nsw @OpenFisca the Haskell source is available in our fork. the commit at github.com/legalese/openf… shows:

1 where the tests came from

2 compilation back to the legislative english ("isomorphism")

3 and to saner natural language (thanks @mattwadd)

4 concrete goal-solving, explained in detail
@BR3NDA @verbman @mattwadd @jamesondempsey @piawaugh @danielselman @craigaatkinson @RoundTableLaw @PolicyLabAU @digital_nsw @OpenFisca here's the source L4 AST that underlies all of those representations. The language can, of course, be remixed to support other legislative arithmetic; in a future iteration we might just parse all the OpenFisca and translate into L4.

During walk&talk with CS intern yesterday: "what is stepwise refinement?"

Great question!

It offers an opportunity to relate specification languages and implementation languages, and hence to relate both to computational law.

Let me explain…
Programmers write programs in a language like Java. The program gets compiled, first to a binary suitable for the Java Virtual Machine; then the JVM executes the bytecode, converting it, ultimately, to machine code: CPU instructions.

It's not actually turtles all the way down.
In this little diagram, you start on the left, and move right.

program ––> compiler ––> bytecode ––> machine code ––> CPU ––> ⚡️

So, my thread on how to choose databases for your web apps starts in 20 minutes time. Hope y'all are ready ?However, this time i would love it to be an interactive session where we can learn from each other about database preferences for specific web apps and the use case
#thread
This is what we want to talk about today. Take a really good look at the image below. Study it well. Also notice the words at the 3 vertexes of the triangle. CONSISTENCY, AVAILABILITY & PARTITION-TOLERANCE (Big English - but fear not, we shall demystify all and it'll all be easy)
If we also look at the image in the previous tweet on this thread we can see some popular databases placed at certain sides of the triangle. It is important to note also the positioning of some of a particular point on each side. We shall discuss this in more detail soon. #thread

1/19 Great article in @theeconomist - explains that Entertainment is what drives internet use for the next 1bn users. economist.com/briefing/2019/… (paywalled) some highlights below:
2/19 Indians now use nearly three times as much data on their phones as Americans:
3/19 “The second half of the internet will for the most part speak languages other than English and Mandarin. It will have little to no experience with other digital media. It will also come online almost entirely on mobile devices.”

Happy to say our @AcadMedJournal article on #wikifying clinical documentation is now in print. Time to recapitulate the Twitter explainer from a few months ago! 1/n @jefferyrlsmith
As an enthusiastic @Wikipedia user, producer of clinical docs at @VUMChealth, and deputy editor of the medical wiki HemOnc.org, I teamed up with @jefferylsmith (VP of Public Policy at @AMIAinformatics) & Adam Wright @BrighamWomens to put out this thought piece 2/11
We came together around the groundswell of concern about the negative effects of #EHRs on the quality of clinical documents. Having delved deep into the history of clinical documentation, we began to realize how far afield from original intent we are. 3/11

I have reached a whole new level of #PISSEDOFF.

I didnt think such a #dark and #scary state, or level, could be reached. It may top 12-14-17's causation. It's. That. Bad. So, I've prepared a statement...

docs.google.com/document/d/1_J…

#PascoSheriff #HaveYouAllNoShame @CigarCityBeer
Dear @FBI,
I must implore you ask your colleauges in @FBITampa to help research this new level of #PISSEDOFFNESS. As locals, they may offer a special indepth knowledge of this new level I have reached. This is not fair & law enforcement must #investigate. No one deserves this.
This is my #apogee of #Pissedoffness.
If #motherfuckers & #tears werent a noticable level.
If #HUSH or #INTIMIDATION tactics being deployed didnt strike a chord.
If #EVIDENCE, PROOF, or 30k Bonds didnt #WOW YOU.
If posting mom with no shred of investigatable value wasnt enough...

2 friends one in mid 30's (F1) and another in mid 40s (F2) met up after almost a decade.. after sometime the conversation was about politics and slowly they were up n about discussing the situation over past 5 yrs..

The conversation went as thus -

1/n
F1: hey have u seen the way India has zoomed back into the top 5 economies of the world?
F2: yes, I heard that. Infact they r on the verge of moving into 4th spot pretty soon n into 3rd spot in next 5 yrs or so if the same level of pace continues

2/n
F1: isn't it shame that it took us so long to get there while many other countries smaller than us that got freedom at about same time as us have zoomed past us
F2: yes that's true but we had our own challenges and in any case let bygones be bygones
F1: yes I agree

3/n

ok, one retweet, one #prolog tip/fact
#SWIProlog comes with a very nifty IDE. start swipl myfile.pl
?- edit. You're in pceEmacs, an emacs clone running in your vm.
C-c C-n to get a project navigator, menus to get thread monitors, debug message window.
#Prolog is a 'closed world' system. If Prolog can't prove it, it's false.
OWL, reasoning for the semantic web, is open world, and assumes there might be more triples it doesn't know.
Closed reasoning is more powerful, but is, well, "closed minded".
