A web portal why and how ?

• It can be accessed from everywhere and by
  everything (desktop, laptop, PDA, WAP phone).
• It can keep the same user interface to several
  back-ends (grid dialects ? command-line UIs).
• It must be redundantly secure at all levels 1)
  secure for web transactions, 2) secure for user
  credentials, 3) secure for user authentication,
  4) secure at VO level.
• All available grid services must be incorporated
  in a logic way, just one mouse click away.
• Its layout must be easily understandable and user
  friendly.

ILDG

• Configurations as LQCD resources
• Different algorithms and implementations
• Different data file format
• Standardize metadata to describe configurations
• Management
• Implementation
• Configuration

11
ILDG

• XML for metadata
• Last draft at Lattice 2003, Tsukuba
  (hep-lat/0309029)
• Evolving with LQCD people contribution

XML to SQL
13
Software

• PERL scripts
• DOM parser
• Storing procedure
• Several DB querying procedures
• All this is handles from GENIUS

Summary and conclusions (1/2)

• ILDG is defining a metadata XML structure to help
  LQCD people to share their work
• The Grid offers a proper tool to physically
  sharing the files world wide in a secure way
• We implemented a trial service to
• Store configurations
• Search between configuration by querying XML
  informations
• Show the search result and, potentially, download
  the data
• GENIUS offers a quick and simple way to build a
  WEB interface to these services to simplify their
  use
• GENIUS is the targeted Grid-portal for Generic
  Applications in EGEE-NA4 (kick-off meeting in
  Paris on Dec 18)
