GSoC 2014 -Extend Construct to build quads
Hi all,
I'm Ujitha Iroshan, third year undergraduate from Department of Computer
Science and Engineering University of Moratuva Sri Lanka. Currently I'm
working as an intern in WSO2 inc an Open source middleware company.I'm
planing to participate in the Google Summer of code 2014. And I'm very much
interest in the project idea of "Extend Construct to build quads" [1]. So
to start with the project I need to have more details about the project.
Can some one please explain the project requirements in details. ?

Hi Andy,
I have followed the tutorials about SPARQL and RDF and I found them very
interesting. I think I'm very confident to work with these technologies. In
the tutorials I have used jena-arq sparql processor and jena fuseki server
as well.
I have check out the jena development code base as well. In order to modify
the jena-arq and jena-fuseki so that SPARQL query can result in RDF Dataset
instead of RDF graph which modules in the code base I should look into?
I'm considering to start create the project proposal, can you please
mention the specifics that need to be in the proposal?
Thank you

HI Andy
Thank you for the quick reply and the details.I'm going through the SPARQL
and RDF features and getting familiar with them.
Now it's been three months out of my six months internship. I have worked
in a project QA portal last month which is a portal for the QA team to
manage their test data. I have used WSO2 Application server[1] which
contains jaggery server component and Data service server[2] component.QA
Portal front end is a jaggery application which runs on the jaggery server
and DSS is used as an interface to back end MySql database. And used LDAP
authentication to authenticate the user.
Currently I'm working with the WSo2 CEP(Complex Event Processor)[3]
team.I'm building a try it feature for the WSO2 CEP which can simulate the
CEP services.

Hi Ujitha,
Thank you for your interest.
The standards SPARQL 1.0 and 1.1, CONSTRUCT returns a single RDF graph -
that is a set of triples. RDF also has the concept of a collection of
graphs, an RDF Dataset.
This project would be working to modify Jena (specifically, the query
engine, part - module jena-arq - and the SPARQL server jena-fuseki) so
that a SPARQL query can result in an RDF Dataset.
"quads" are another way of talking about that - an RDF dataset can be
recorded as a set of quads (which in itself is a partial lie :-) - it's
a set of triples for the default graph and a set of quads, for data from
the named graphs). We tend to talk about quads to include triples and
about quads as the implementation of the formal concept of RDF Dataset.
Take a quick look at the relevant of the standards, if you haven't
already, to get some familiarity with features:
* SPARQL 1.1 Query
* SPARQL 1.1 Update (because a similar feature exists there in INSERT)
* RDF 1.1 N-Quads
* RDF 1.1 TriG
Jena already has readers and writers for those syntaxes - it's not part
of this project.
Part of the project, as with any project, is getting from a general
design to the specifics. That would be part of the project after starting.
As an intern at WSO2, what have you personally been working on and been
responsible for and involved in?
I can see that you've made 101 commits but that does not give the
context for the work.
Andy
