Activating Qworum for a website

Qworum provides advanced browser capabilities through a browser extension. By default Qworum is actived for local development only. Activating Qworum for a website requires a subscription.

Usage

Tip: Run the examples below by typing this in your terminal (requires Deno):

deno run --allow-net --allow-run --allow-env --allow-read --location https://site.example/a/page.html https://deno.land/x/[email protected]/mod.ts --dax=false --mode=isolated https://raw.githubusercontent.com/doga/qworum-for-web-pages/master/README.md

Generate a Qworum script in-memory.

'''

import { QworumScript, Qworum } from 'https://esm.sh/gh/doga/[email protected]/mod.mjs';

const
Script   = QworumScript.Script.build,
Sequence = QworumScript.Sequence.build,
Call     = QworumScript.Call.build,
Goto     = QworumScript.Goto.build,
script   = Script(
  Sequence(
    Call(['@', 'shopping cart'], 'https://shopping-cart.example/view/'),
    Goto("/home/")
  )
);

console.info(`${script}`);

// In a browser the Qworum extension would run the Qworum script.
// await Qworum.eval(script);

Sample output for the code above:

Sequence(Call(object: [@, shopping cart], href: https://shopping-cart.example/view/),Goto(href: /home/))

Create semantic data sourced from a Turtle file.

import { SemanticData, Qworum } from 'https://esm.sh/gh/doga/[email protected]/mod.mjs';

const org = new SemanticData();

await org.readFromUrl(new URL('https://qworum.net/data/org.ttl'));

console.info(`${org}`);

// In a browser the Qworum extension could store this as session data.
// await Qworum.setData('Organisation', org);

Sample output for the code above:

SemanticData(
  …
  <https://qworum.net/data/org.ttl#id> a <http://www.w3.org/ns/org#Organization>, <https://w3id.org/okn/o/sd#Organization>;
      <http://www.w3.org/ns/org#purpose> "Qworum is a provider of enterprise infrastructure software, with the overarching goal of making the web a fully fledged platform for applications."@en;
  …
)

Qworum scripts must not contain platform faults.

import { QworumScript, Qworum } from 'https://esm.sh/gh/doga/[email protected]/mod.mjs';

const
Script     = QworumScript.Script.build,
Fault      = QworumScript.Fault.build,
faultTypes = ['* entitlement', 'payment cancelled', null];

for(const faultType of faultTypes){
  try{
    const script = Script(Fault(faultType));
    console.info(`${script}`);
  }catch(error){
    console.error(`${error}`);
  }
}

Sample output for the code above:

TypeError: not a service-specific fault: '* entitlement'
Fault(type: payment cancelled)
Fault(type: * service-specific)
