Eucalyptus: A Service-oriented Participatory
Design Studio Supported by UCLP

Sandy Liu, Yong Liang, Bo Xu, Bruce Spencer

Abstract
While most service-oriented solutions are developed for gluing systems
or data together, the Participatory Design Studio (PDS) is developed to
manage and configure the resources needed by users engaging in a partici-
patory design session: e.g. videoconference application, and visualization
server. User-Controlled Lightpath Provisioning (UCLP) pioneers a user-
centric approach for creating and managing a private end-to-end optical
network dynamically. Harnessing the power of UCLP, the PDS strives to
provide a set of upper layer services for non-technical users to provision
devices and applications running on high-speed broadband networks.
Funded through CANARIE's Intelligent Infrastructure Program, this
project investigates ways to build an agile Service-oriented Architecture
(SoA) consisting of a set of fine-grained Web Services to manage and
configure available resources. We also provide a workflow management
service allowing users to orchestrate services to perform certain tasks.
For example, a workflow for rendering allows a user to specify a set of
files as input from his/her local machine, upload them to the file server
through the file management service, then start a rendering task managed
by the rending service; when the rending task is completed, the output
will be processed by the visualization service, through which the output
will be displayed to the user. In addition, we employ simple semantics
to describe the dependencies of each resource and ensure that workflows
adhere to these dependencies. The goal of the PDS is to construct a
network of services that can support (building) architect teams distributed
across different geographical areas to work in an effective collaborative
environment.
