The service-oriented approach to linking software systems
and applications is transforming the way many organizations
share data.
This approach improves existing methods
of data sharing by providing a service layer between systems.
Sharing data between applications
is a well-established principle that works on a simple level.
As systems expand, the solution that
connects two software applications
will often not work for a third.
What began as a workable system then
locks valuable data in a silo.
Sharing the data is still possible but requires
adaptations and tweaks.
The process is laborious and time-consuming,
leading to bottlenecks and overload.
The reality of this world is unnecessary effort expended
in duplication of data.
By applying a service layer to the applications
you wish to connect up, data is offered out
in a common format for reuse elsewhere.
The service-oriented approach works with existing software
systems and does not require you to remove
the monolithic application.
Placement applications reuse the links already
made and can plug into the service layer
without affecting other users of data.
New applications can be added to grow overall system
architectures in the same way.
The data in each application is offered up
as a service, which any other application can consume.
When the service-oriented approach
has evolved into a system-wide architecture,
it allows connections and service sharing opportunities
between organizations nationally and globally.
Take monitoring of student progress, for example.
Results are locked by a virtual learning environment,
but how much of that data is shared with the management
system that is tracking progression against funding?
If the motivation and commitment of struggling students
is not addressed, and they decide to walk away,
there is a direct impact on funding.
If the data is freed up and shared across a system using
a service-oriented approach, it could
contribute to retaining student motivation,
and thereby maximizing income.
And what if across the education community
there was one standard and agreed way
to describe a course?
It would allow course information
to be made available as a consumable service
both internally and externally.
This is the subject of a current project called
exchanging course-related information,
or XCII, encompassing course marketing, quality assurance,
enrollment, and reporting requirements.
This service-oriented approach enables
aggregated organizations like UCast to gather the standard
and agreed descriptions of courses from each provider.
Comprehensive details of approved enrollment
opportunities are then returned to a prospective student
for easy and accurate comparison.
Amongst the research community, it is the same principle.
Here, the service-oriented approach
is enabling researchers to work across institutions
in virtual organizations.
myGrid is a project that provides a shared tool
kit for creating experiments by coordinating the information
flow between distributed resources and services.
Workflows and query specifications
link together remote and local resources
using web service protocols.
Workflows created by myGrid represent
the scientific process of the experiments they enact,
making them a rich resource for scientists creating
their own new experiments.
The service lab to this data enables
users to share, reuse, and repurpose experiments
within the myGrid community.
Many education and research services
are already developing a service-oriented approach,
taking their lead from the business world
and major software developers.
It is in this context that the e-Framework,
a successful and expanding international initiative,
works to make sense of the service-oriented approach
for the education and research community.
The e-Framework website identifies and describes
the service components needed.
It provides the blueprints and reference examples
for those in the community who want to gain a greater
understanding and knowledge of how to implement
a service-oriented approach.
The e-Framework website is thus becoming a knowledge base
that is developing a shared vocabulary
and way of thinking for all in education and research.
