SD connectors
q  Making-up


Development in SD

q  Developed in Perl 5

q  Object-oriented with Moose


Example with Github bugtracker

q  3 classes in Replica/

ü  github.pm

ü  github/PullEncoder.pm

ü  github/PushEncoder.pm


Partial UML diagram (inheritance)


Example with Github

q  Perl interface for github.com

Net::GitHub::V2


Example with Github

q  github.pm module
$sd clone –-from
‘github:http://github.com/arroway/SD/issues’

ü  Authentification (OAuth or basic auth)

ü  Connection


Example with Github

q  github/PullEncoder.pm module

find_matching_tickets

calls

github->issue->list(‘open’)
github->issue->list(‘closed’)


Example with Github

q  github/PushEncoder.pm module

integrate_ticket_create/update

calls

$github->issue->open/edit


Net-OSLC-CM Perl Module

Simple Defects (SD)
SD connectors
Development goal
q  Making-up


Net-OSLC-CM

q  Standard Perl module

q  Helping implement a OSLC-CM Consumer


Example

use Net::OSLC::CM;

my $oslccm = Net::OSLC::CM−>new(
url => $self−>remote_url,
username => $username,
password => $password
));

# Getting an array of changeRequests
my @results = $oslccm−>get_oslc_resources;


Résultat final

my @results =
$oslccm−>changeRequests;


Detailed example

$oslccm−>url = "http://example.com";

$oslccm−>parser(
Net::OSLC::CM::Parser−>new(cm => $oslccm)
);

$oslccm−>create_catalog;
$oslccm−>get_provider_catalog_resource;

$oslccm−>get_service_providers;

$oslccm−>get_changeRequests($oslccm−>providers);
$oslccm−>load_changeRequests();

my @results = $oslccm−>changeRequests;

Commits in Net-OSLC-CM


Next development steps

q  Implementing the Push part in Net::OSLC::CM
with a serializer RDF/XML

q  Implementing PushEncoder.pm in SD

q  Completing the implementation of the specs

q  Refactoring Net::OSLC::CM
ü  RDF data are extensible – so is the
Prophet database
ü  Data OSLC/ Net OSLC


What I learned

q  Perl 5 and OO Perl with Moose

q  Creation of a Perl module

q  Tests with Test::More

q  Specifications OSLC-CM v2

q  Searching through RDF data and
performing SPARQL queries
