The next 20 minutesSemantic Web + XO = SemanticXO

One Laptop Per Child and the XO

Linked Data / the Semantic Web

Goals of the project SemanticXO

Publish and Consume Linked Data with the XO

Your questions, remarks, suggestions !

Work in progress


One Laptop Per Child

One Laptop Per Child (OLPC)

“Empower the world’s poorest children through education [by providing them] with a rugged, low-cost, low-power and connected laptop” – laptop.org

Mission principles

1.Every child owns his laptop

2.Action focused on early education (6-12)

3.No one gets left out

4.Connected device

5.Open source software free to grow and adapt


The XO laptop and Sugar

Collaborative learning

Activities instead of applications

Journal of usage (critical thinking)

Example of current capabilities

Fully featured web browser

Snapshot of Wikipedia

Activities running simultaneously can share data

Bulk export of journal entries (for backup)

The XO is Web 2.0 ready : create and share data in data silos


Linked Data (aka Semantic Web)

Linked Data“Using the Web to connect related data that wasn't previously linked, or (...) lower the barriers to linking data currently linked using other methods” – linkeddata.org

Publish data on Internet as already done for documents

Design principles

1. Use URIs as names for things

2. Use HTTP URIs so that people can look up those names

3. Bind useful information to the URI, using the standards

4. Include links to other URIs

Relation with “Air Tanzania” Air Tanzania has its HQ in Dar Es Salaam

Application


Open Data

“A piece of content or data is open if anyone is free to use, reuse, and redistribute it — subject only, at most, to the requirements to attribute and share-alike” – opendefinition.org

Open Data published by UK, USA, France, Finland, Ireland, Kenya, … http://datacatalogs.org/

SemanticXO

Goal: make the XO ready for the Web 3.0 by extending its software stack

OLPC contributor project started in October 2011 for 12 months

What is there to expect ?

Benefits for the operating system

Flexible and dedicated data storage solution

Benefits for activities developers

Easier data access and integration

Access to the content of the LOD Cloud

Benefits for end users

Increased sharing opportunities


How to do it ?

Implement a software stack

“Triple store” to store the data

Interface to publish/consume data

Triplestore and files

Programming Interface (API)HTTP server


Example of application

Knowledge Acquisition of traditional Amerindian World views using Serious Games


Under the hood : data model

Resources and relations


Under the hood : data stored

olpc:resource/78cbb1f0 rdf:type olpc:Box

... ... ...

An item

A box

Set of triples (SPO)

Same structure everywhere in the Cloud

e.g. Can be linked to cities for provenance


New data flows

Data distribution Easy access


Partnership with W4RA-VOICESWeb alliance for Regreening in Africa (W4RA)

“initiative to help extend the Web benefits of the knowledge society and economy to people in rural communities in Africa”

http://www.w4ra.org/

Project VOICES funded by European Union

http://www.w4ra.org/

http://vimeo.com/26520353


Aimed at expanding knowledge creation and sharing, especially in poor communities in Africa, with have limited access to the Web.

Use voice technologies, mobile phone and community radio for communication and access to information

Working to create access to the Linked Open Data and to create an Open Web of Speech

Use triple stores and RDF for spoken data

Take home messageLinked Data = best practices for publishing and interlinking structured data on the Web

Web scale data sharing

Lots of data published as Linked Data

World's largest information network

Linked Open Data can contribute to development with more, easier, data sharing
