Situation Analysis

Agility is the timeless pursuit of
enterprises and individuals alike.
In all cases, access, integration,
and dissemination of data is
pivotal.


Linked Open Data (LOD) Cloud


Situation Analysis
Data is growing exponentially along the
following dimensions:
•Volume -- production

•Velocity – dissemination fire-hoses

•Variety – APIs and underlying data Models

•Virtuosity – insight discovery expectations.

All of this happens while the total hours in day
remains constant at 24 hours!


Product Value Proposition

Enterprise and Individual Agility
via Data Virtualization, without
compromising performance,
scalability, security, or
investments in existing
infrastructure!


Product Architecture

A high-performance, scalable,
secure, and operating-system-
independent server designed
to handle contemporary
challenges associated with
data access, data integration,
and data management.


Data Virtualization Middleware

An in-built middleware layer
(“Sponger”) for creating
Linked Data Views over
Heterogeneous Data
Sources.


Pluggable Linked Data Cartridges/Drivers

A collection of prefabricated
and customizable Data
Extraction, Transformation,
and Lookup cartridges
(drivers) covering a vast
ranges of data formats and
data access protocols.


Sophisticated Content Crawler

DBMS hosted Content
Crawler that leverages
loosely coupled binding to
the Sponger Middleware
component for
transformation of
unstructured and semi-
structured data into Linked
Data.


How Do I Get Going?

 Download, install, and experience the power of coherent
integration of disparate data sources, data access protocols,
and data representation formats.

 In an nutshell, commence exploitation of powerful business
intelligence, socially enhanced collaboration, data
virtualization, and entity analytics without writing a line of code!

 Turn "Big Data" into exploitable "Smart Data"
without compromise!


How Does Virtuoso Expose LOD Cloud
Data To ODBC Clients?
 Creation of ODBC accessible SQL Views using
SPASQL (SPARQL inside SQL) that targets local
data
 Ditto via SPARQL-FED (Federated SPARQL) for
external SPARQL endpoints.

Example instances include:

 DBpedia (Linked Data version of Wikipedia content and LOD Cloud nexus)

 URIBurner Service for “on the fly” transformation of data from: LinkedIn, Facebook,

Twitter, Google+, Freebase, Disqus etc.

 Live Linked Open Data LOD Cloud Cache.
