Content 1 2 3 4 5 . . . . . Rational and Objectives OPTICON Network 3.6 High-level Requirements Architectural Concept Roadmap

Supported by OPTICON and NVO:
OPTICON has received research funding from the European Community's Sixth Framework Programme under Contract no. RII3-CT-2004-001566 The US National Virtual Observatory (NVO) is funded by the National Science Foundation under cooperative agreement AST0122449


Rational and Objectives
Current issues for data processing Many systems available but:
Designed several decades ago, Largely incompatible due to scripting language, Complicated to share data/code

Only limit interfaces to Web, archives, databases and VO Difficult to exploit available computer resources Too complex to upgrade current system Future astronomical software environment objectives: Simple and flexible scripting language Open, free base system for desktop Easy interface to resources like archives, VO, GRID, etc. Access to important legacy applications Scalable from desktop to clusters Simple to develop new applications

High-level Requirements
Key requirements for astronomical software environment: Core system available in a license free version Promote sharing and collaboration with respect to data and code Support of astronomical standards and conventions Prepared to support units and error propagation Powerful scripting language e.g. Python Simple but extendible to provide scalability Good integration with Web services and VO Easy development of new task (e.g. In C, C++ and Fortran) Access to important legacy applications (e.g. From AIPS, IRAF, GIPSY, MIDAS) Draft document with detailed requirements (190+) available Internal written review completed External written review foreseen for fall 2006

Roadmap
Near term roadmap: High-level requirements ­ 2007 Q1 Architectural concept ­ 2007 Q2 Interface specifications ­ 2008 Q1 based on
Prototypes ­ 2006 Q4 .. 2007 Q3

Main objectives Share views on requirements and architectural concept Provide common basis for implementations Promote interoperability to ease sharing of code and data Find resource to start actual implementation See poster for SPS6 on 2006-08-22
