2. EMI INFSO-RI-261611 2 Overview EU FP 7 EMI Consortium Overview of AMGA Belle II User Requirements Analysis AMGA Web Application Product Features Design of AMGA Web service Conclustion and Plan 27/02/2013 Design of AMGA Web Application Based on Belle II User Requirements

3. EMI INFSO-RI-261611 27/02/2013 Design of AMGA Web Application Based on Belle II User Requirements 3 EMI (European Middleware Initiative) – EMI: EU co-funded project started in May 2010 and lasting 36M – It consists of 24 beneficiaries(22 established in European Countries & 2 in Asia). ※ 2 Asian country: KISTI(Korea), ASGC(Taiwan) – EMI brings together the 4 major European middleware To deliver a consolidated set of middleware components for deployment in all major Distributed Computing Infrastructures To extend the interoperability between grids and other computing infrastructures To strengthen the reliability of services To evolve the middleware for the benefit of its user communities KISTI – KISTI is leading AMGA’s evolution and development in EMI EMI Consortium

4. EMI INFSO-RI-261611 4 AMGA The Official EMI Metadata Software/Service – De facto standard metadata catalog service for grid community – Collaborative development among KISTI (Korea), CERN (Switzerland) and INFN (Italy) AMGA Website located at CERN 27/02/2013 Design of AMGA Web Application Based on Belle II User Requirements Projects & Applications utilizing AMGA

5. EMI INFSO-RI-261611 5 Belle II user requirements Analysis Classification User Requirements Accessibility Minimize firewall and security issues Run stand-alone against Grid UI Use easily with Grid authentications(Grid/VOMS proxy) Use directly with X.509 cert. and ID/PW authorization Functions Simplification Simplify a number of functions for Belle II general users compared with AMGA Manager Server set-up Modify environment variables in configuration files Manage a list of AMGA Sites Manage AMGA service running(start, stop, restart) Client OS Reduce the OS dependency Interface Support Various Web browser(IE, Firefox, Chrome, etc.) Data In/out Support a large-scale data in/out 27/02/2013 Design of AMGA Web Application Based on Belle II User Requirements

6. EMI INFSO-RI-261611 6 AMGA Web Application Goal: – Provide easy-to-use AMGA Web interface to AMGA users without any client programs. – Enable Admin to control server set-up – Support fast retrieval for site metadata Allowance – AMGA admin : modify AMGA config., control service, manage list of other sites – General Users : manipulate metadata schema, Collection, entries, AC, G/U info, Site info Several views already now – reusing the components from AMGA Manager(basic workbench, viewer, intro, edit part, etc) 27/02/2013 Design of AMGA Web Application Based on Belle II User Requirements

7. EMI INFSO-RI-261611 7 Product Features 1.Interaction with the AMGA services 2.Ideally everything available in the AMGA Manager should be also possible with the web browser 3.list of all available AMGA servers related to main AMGA server 4.Management of AMGA configuration and running service for main AMGA server(start & stop) 27/02/2013 Design of AMGA Web Application Based on Belle II User Requirements

8. EMI INFSO-RI-261611 8 Design of AMGA Web Service 27/02/2013 Design of AMGA Web Application Based on Belle II User Requirements AMGA Web Service AMGA Server 자료 DATA Internet GRID RDB Valid Authen. Multi-users access AMGA web service based on Grid environment as well as existing environment with their valid authentications using only web browser

9. EMI INFSO-RI-261611 9 Conclusion Metholology: Fast prototyping development cycle Development reflecting Belle II user requirements Various authentications including VOMS proxy Support multi-users to access AMGA service Strengthen the functionalities of metadata catalog administrator Plan Reflect requirements more Test and Stablize the application Distribute to Belle II AMGA site via Belle II Distributed Computing Group after verification of this application 27/02/2013 Design of AMGA Web Application Based on Belle II User Requirements
