What if

dr. Erik Mannens @erikmannens

Open Data, Linked Data, and Big Data

We need

together


Open Data


Way of … Thinking


Silos of Data


“Stop Hugging your Data”



e.g. … Open Learning


Open Data Linked


Way of … Publishing


Semantic Web



Connect your Silos


5-stars (Technical Perspective)

Open Linked Data (Tim Berners-Lee)

Make your Stuff available on the Web

Make it available as Structured Data

In a non-proprietary Format

Use URLs to identify Things, so one can point at your Stuff

Link your Data to other People’s Data to provide Context


5-stars (Organisational Perspective)

Open Data Engagement (Tim Davies)

Be Demand-driven

Provide Context

Support Conversation

Build Skills & Capacity

Collaborate with the Community


5-stars (Functional Perspective)

Open Data Portal Functionalities (iMinds)

Dataset Registry

Metadata Provider

Co-creation Platform

Data Publishing Platform

Common Data Hub


Data as Commodity


Sidenote


15’ Open Data Publishing Framework

e.g. data.gent.be

opendata.antwerpen.be


Publishes 2 to 5 Star Data

tdt/core tdt/input triple store


REST-full API for Developers

triple store

core RESTful data adapter

CSV

XLS

JSON

XML SPARQL endpoint

...

e.g. datatank.gent.be/Grondgebied/Straten or data.irail.be/NMBS/Stations



Data BIG


Way of … Analyzing




How Difficult Can It Be?


Collaborative Effort found Higgs Boson


•  Data use is expected to grow by as much as 44 times, amounting to some 35.2ZB (zettabytes -- a billion terabytes) globally

•  Sensors, social media feeds, photos, video and cellphone GPS signals account for 2.5 quintillion bytes of data per day

•  More than 50% global population lives in cities and this number is forecast to rise to 69% by 2050

•  The number of city residents is expected to grow from 3.5 billion to 5 billion in the next 20 years

•  ‘Internet of Things’ Age is approaching: 25 billion devices connected to the Internet by 2015 and 50 billion by 2020

•  Access to public data is estimated to be worth €27 billion in the EU •  ICT-enabled energy efficiency could translate into over €600 billion

worth of cost savings for the public and private sector

Big (Data) Bang in Smart Cities


What if it were

OPEN & LINKED


e.g. … OpenTransport


e.g. … OpenTransport


•  From a rigid analog system to a smart, dynamic, digital and automated energy delivery system

•  How much excess energy will be available, when to sell it and whether the grid can transmit it?

•  When and where equipment downtime and power failures are most likely to occur?

•  Which customers are most likely to feed energy back to the grid, and under what circumstances?

•  Which customers are most likely to respond to energy conservation and demand reduction incentives?

•  How to manage the commitment of larger, traditional plants in a scenario where peaks from distributed generation are becoming relevant?

Then …


What if it were

OPEN & LINKED


e.g. … bi-directional sensor network










e.g. … OpenEnergyMonitor




e.g. … Big Data … in Iceland?


e.g. … a Trillion Sensors … in Iceland!
