Abstract:
Many international Grid projects have been
launched recently in order to face the enormous amount of astronomical
data which is pro- duced and/or will be produced in the next years by
the new genera- tion of large telescopes and CCD mosaic
detectors. Grid is the effective and natural solution for the CCD
mosaic data processing but due to complex composition of astronomical
applications a Grid workow management system is required in order to
simplify the description of nested tasks execution, monitoring and
data handling. The recently released Business Process Execution
Language for Web Services (BPEL4WS) speci cation is positioned to
become the standard for Web services composition. It allows you to
create com- plex processes by creating and wiring together different
activities that can, for example, perform Web services invocations,
manipulate data, throw faults, or terminate a process. The evolution
towards a service-oriented architecture, supported by emerging
standard, is an activity that has many attention. This issue is being
tackled within the EU-funded EGEE project (Enabling Grids for
E-science in Europe) whose primary goals are the provision of robust
middleware components and the creation of reliable and dependable Grid
infrastructure to support e-Science applications, using an archi-
tecture that offers a Web Service interface. We present a proposal for
the execution of astronomical data analysis workflow on a
service-oriented Grid architecture using the new standard language
BPEL4WS.
