What is Data?

Subject Observation Representation.
Basically:
Every “Observation Subject” has a
Name, discernible Attributes, and
“Attribute Values”.


What is Structured Data?
Schema Constrained Data Representation
Where the following are human and/or machine
discernible:

 Unique Subject Name

 Subject Attributes

 Subject Attribute Values.


CSV based Structured Data
Entity,Attribute,Value
#France, #Type, #PopulatedPlace
#France, #hasLabel, ”France”
#France, #hasCapital, #Paris
#Paris, #Type, #PopulatedPlace
#Paris, #hasLabel, ”Paris”
#PopulatedPlace, #Type, #Place

TSV based Structured Data
Entity<TAB>Attribute<TAB>Value
#France<TAB>#Type<TAB>#PopulatedPlace
#France<TAB>#hasLabel<TAB>”France”
#France<TAB>#hasCapital<TAB>#Paris
#Paris<TAB>#Type<TAB>#PopulatedPlace
#Paris<TAB>#hasLabel<TAB>”Paris”
#PopulatedPlace<TAB>#Type<TAB>#Place


Structured Data (Table/Spreadsheet)

Entity (Subject) Attribute (Predicate) Value (Object)
#France #Type #PopulatedPlace
#France #hasLabel “France”
#France #hasCapital #Paris
#Paris #Type #PopulatedPlace
#Paris #hasLabel “Paris”
#PopulatedPlace #Type #Place


What is Linked Data?

Basically, Hyperdata!
Enhanced Structured Data
Representation
Via
Hyperlinks.


What Are Hyperlinks?
Live References To Content.
These References my be local (Green
Hyperlinks from Windows Help)
Or
Network aware (Blue Hyperlinks as per World
Wide Web & Other HTTP Networks).


Local Linked Data using URIs

Massive Linked Open Data Cloud


SQL Query Language Benefits?

Declarative Query Language for Access,
Manipulation, and Definition of
Structured Data Stored in Relational
Database Management Systems
(RDBMS)


ODBC Benefits?

Standard Application Programming
Interface (API) for SQL based
Access to RDBMS hosted Data.


SPARQL Query Language Benefits?

Declarative Query Language for
Access, Manipulation, and
Definition of Linked Data based on
the Entity-Attribute-Value/RDF
Data Model.


SPARQL Protocol Benefits

HTTP based Protocol (Web Service)
for executing SPARQL commands
against Public or Private Linked
Data Sources.


SQL Query Language Challenges

Access to Data outside Relational
Database Management Systems.


ODBC Driver Problems?

Access to Data outside Relational
Database Management Systems.


Virtuoso ODBC Driver Benefits?

Cross Platform ODBC Driver that
treats Linked Big Data on the Web
(or elsewhere) like any another
ODBC accessible RDBMS!


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.


Demo Query Tools
Microsoft Access (Windows)
Filemaker (Mac OS X)
Tibco SpotFire (Windows)
Tableau Deskop (Windows)
SAP Crystal Reports (Windows)
HTML5 based ODBC Explorer (Browser) – requires local ODBC
Driver Manager
HTML5 based XMLA Explorer (Browser) – no local ODBC Driver
Manager required
Virtuoso Conductor
Virtuoso iSQL
Any other ODBC compliant tools that offers a SQL Query Editor.


Sample SPARQL Endpoints
Live Virtuoso Demo Server – Focal Point (SPARQL and
HTML5 XMLA-ODBC Client) for all live demos in this presentation
DBpedia - Structured Data rendition of Wikipedia content
Linked Open Data Cloud Cache – majority of datasets published to
the LOD cloud
URIBurner – Live Linked Data Transformation Service for Web Pages
& Web 2.0 Services
Health.Data.Gov – U.S. Govt. Health Dept. Information Portal
Data.Gov.UK – UK Government Open Data in Linked Data form
Reegle – Pan European Renewable Energy Information Portal
OpenEI – U.S. Govt. Energy Dept. Energy Information Portal
Nature.com – Nature Publishing .


Federated SPARQL (SPARQL-
FED)Queries


How It Works

Construct or Locate SPARQL Query of interest

Verify Query against its original SPARQL Endpoint

Go to a Virtuoso SPARQL endpoint and execute a Federated

SPARQL (SPARQL-FED) variant of query

Using any ODBC compliant application, execute SPARQL pass-

through queries by placing the pragma “SPARQL” before your Basic or

Federated SPARQL query text.

SQL Views derived from SPARQL
Queries


How It Works
Construct or Locate SPARQL Query of interest

Verify Query against its original SPARQL Endpoint

Go to a Virtuoso SPARQL endpoint and execute a Federated
SPARQL (SPARQL-FED) variant of query
Via Virtuoso’s native or ODBC SQL client interfaces issue standard
SQL CREATE VIEW syntax to construct a SQL View from the
SPARQL-FED
Using any ODBC compliant application, query the SQL View as you
would any other ODBC accessible SQL View.
