Tina:

You may also find some useful information in this talk that I gave a
while back, on using SemWeb technologies - specifically including
Apache Jena and Apache Stanbol - in an enterprise setting.

This page links to both the video recording and the slides from the talk.

Re: Web 3 vs Web 2

2017-06-07 Thread David Moss 
To see the metadata you have to consider the prefix statements that must be 
made before you can use the triples in your example/

@prefix rdf: http://www.w3.org/1999/02/22-rdf-syntax-ns#

click on the hyperlink to follow it.

Using this prefix statement adds metadata essential to understanding the triple:
Student rdf:type Person

rdf:type means:
rdf:type a rdf:Property ;
rdfs:isDefinedBy  ;
rdfs:label "type" ;
rdfs:comment "The subject is an instance of a class." ;
rdfs:range rdfs:Class ;
rdfs:domain rdfs:Resource .

The object “Person” in the triple may also have metadata associated with it.
If the prefix:

@prefix foaf: http://xmlns.com/foaf/0.1/

is used the metadata associated with foaf:Person is

http://xmlns.com/foaf/0.1/Person; rdfs:label="Person" 
rdfs:comment="A person." vs:term_status="stable">http://www.w3.org/2002/07/owl#Class"/>http://schema.org/Person"/>http://www.w3.org/2000/10/swap/pim/contact#Person"/>http://xmlns.com/foaf/0.1/Agent"/>http://www.w3.org/2003/01/geo/wgs84_pos#SpatialThing; 
rdfs:label="Spatial Thing"/>http://xmlns.com/foaf/0.1/"/>http://xmlns.com/foaf/0.1/Organization"/>http://xmlns.com/foaf/0.1/Project"/>


So you can see even a simple statement like 

Student rdf:type foaf:Person

contains a huge amount of metadata that can be located and used by a machine!

Where is the meta data here. How machines understand this data.

Re: Web 3 vs Web 2

2017-06-06 Thread Trevor Lazarus 
The metadata is right there for a machine to interpret, for e.g. one could
write a bit of JS for the machine to understand that a URI say
http://domain/student-4321 is a type of foaf:Person and not a Parrot and
based on the Ontology(FOAF in this case) look out for a foaf:name
predicate, with a bit more JS one could program the machine to display the
literal value, say "Samantha" with some fancy HTML+CSS. Similarly one could
program the machine to display the address as both a String formatted
nicely and geocoded into a pair of geospatial coordinates on a Map.

Web 3 vs Web 2

2017-06-04 Thread tina sani 
Greetings

I want to ask how Semantic Web provides meaning to our data? How it differs
from the current web.
I will appreciate if some one provide with a simple examples: If we write
an Ontology and develop Semantic Web application, how it differs from a
simple Java application (without Semantic Web) and a traditional database
system?
