cuttlefish facilitates human-friendly HTML rendering of machine-friendly:
- JSON-LD & Schema.org ("story" data)
- dynamb (dynamic ambient data)
- spatem (spatial-temporal data)
- statid (static identifier data)
cuttlefish is lightweight client-side JavaScript that runs in the browser. See a live demo using the code in this repository at: reelyactive.github.io/cuttlefish
Include in an index.html file the required cuttlefish-x scripts, the Font Awesome 5 icon set, and divs in which each can render the data:
<html>
<head></head>
<body>
<div id="storyToRender"></div>
<div id="dynambToRender"></div>
<div id="spatemToRender"></div>
<div id="statidToRender"></div>
<script defer src="js/fontawesome-reelyactive.min.js"></script>
<script src="js/cuttlefish-story.js"></script>
<script src="js/cuttlefish-dynamb.js"></script>
<script src="js/cuttlefish-spatem.js"></script>
<script src="js/cuttlefish-statid.js"></script>
<script src="js/app.js"></script>
</body>
</html>Include in a js/app.js the code to render the given story, dynamb, spatem and/or statid data in the xToRender divs:
let story = { /* Likely retrieved by cormorant.js */ };
let storyTarget = document.querySelector('#storyToRender');
let storyOptions = {};
cuttlefishStory.render(story, storyTarget, storyOptions);
let dynamb = { /* Likely consumed from Pareto Anywhere */ };
let dynambTarget = document.querySelector('#dynambToRender');
let dynambOptions = {};
cuttlefishDynamb.render(dynamb, dynambTarget, dynambOptions);
let spatem = { /* Likely consumed from Pareto Anywhere */ };
let spatemTarget = document.querySelector('#spatemToRender');
let spatemOptions = {};
cuttlefishSpatem.render(spatem, spatemTarget, spatemOptions);
let statid = { /* Likely consumed from Pareto Anywhere */ };
let statidTarget = document.querySelector('#statidToRender');
let statidOptions = {};
cuttlefishStatid.render(statid, statidTarget, statidOptions);Open the index.html file in a web browser to see the story, dynamb, spatem and/or statid data rendered in a human-readable way.
cuttlefishStory.render(story, target, options);
cuttlefishStory.determineImageUrl(story);
cuttlefishStory.determineTitle(story);
cuttlefishDynamb.render(dynamb, target, options);
cuttlefishDynamb.renderIcon(property, target, options);
cuttlefishDynamb.renderValue(property, data, target, options);
cuttlefishSpatem.render(statid, target, options);
cuttlefishStatid.render(statid, target, options);
Provides a ContinuousDataTable class which updates automatically once instantiated:
<table id="continuousData"></table>let elementId = document.querySelector('#continuousData');
let devices = beaver.devices; // See beaver.js
let options = { updateMilliseconds: 15000,
numberOfSamples: 4,
propertiesToDisplay: [ 'temperature', 'relativeHumidity',
'illuminance', 'batteryPercentage' ]
};
let continuousDataTable = new ContinuousDataTable(elementId, devices, options);Provides a DiscreteDataTable class which takes dynamb events via its handleDynamb() function, and updates automatically once instantiated:
<table id="discreteData"></table>let elementId = document.querySelector('#discreteData');
let options = { updateMilliseconds: 5000,
maxRows: 8,
isClockDisplayed: false,
digitalTwins: cormorant.digitalTwins, // See cormorant.js
propertiesToDisplay: [ 'isButtonPressed', 'isContactDetected',
'isMotionDetected', 'unicodeCodePoints' ]
};
let discreteDataTable = new DiscreteDataTable(elementId, options);
// See beaver.js
beaver.on('dynamb', (dynamb) => { discreteDataTable.handleDynamb(dynamb); });
// To update the device name after fetching a digital twin with cormorant.js:
discreteDataTable.updateDigitalTwin(deviceSignature, digitalTwin);Provides a DevicesTable class which displays devices filtered from an optional beaver instance, and/or inserted/removed via its insertDevice() and removeDevice() functions, and updates automatically once instantiated:
<table id="devicesTable"></table>let elementId = document.querySelector('#devicesTable');
let options = { beaver: beaver, // See beaver.js
maxRows: 12,
isClockDisplayed: false,
digitalTwins: cormorant.digitalTwins, // See cormorant.js
isFilteredDevice: function(device) { return true; }
};
let devicesTable = new DevicesTable(elementId, options);
// To update the device name after fetching a digital twin with cormorant.js:
devicesTable.updateDigitalTwin(deviceSignature, digitalTwin);
// To receive notification of a user selection of a device in the table:
devicesTable.on('selection', (deviceSignature) => { /* Selection handler */ });
The cuttlefish isn't actually a fish, but rather a cephalopod, which is a class of marine animals remarkable for how quickly and diversely they can communicate visually. As per Wikipedia: "flamboyant cuttlefish use between 42 and 75 chromatic, seven textural, 14 postural, and seven locomotor elements" to communicate.
Given that cuttlefish.js communicates machine-readable data as human-readable visual information, that unprecedented natural vocabulary sets some serious expectations for UI/UX design! Seriously. Read Jaron Lanier's 2006 article in Discover Magazine.
In its client-side habitat, cuttlefish.js will consume and render the JSON-LD fetched by cormorant.js. And while you may suspect that cuttlefish and cormorants have nothing more in common than the fact that the pupil of the former resembles the distinct wing shape of the latter, check out this video we found on the Internets. Yeah, if that skate were a beaver...
Speaking of videos, we'd be remiss not to share with you Ze Frank's True Facts about the Cuttlefish. May we also suggest an images search for "cute baby cuttlefish". You're welcome.
cuttlefish v2.0.0 was released in February 2023.
cuttlefish.js v1.0.0 was released in July 2019, superseding all earlier versions, the latest of which remains available in the release-0.1 branch.
