Interest Groups

Data Curation Preservation IG

Education IG

High Energy IG

Knowledge Discovery IG

Operations IG

Ongoing activity:

• Monitor VO health:
  • Coordinate "weather reports" (service compliance)
• Address non-compliancy:
  • Identify common/persistent errors
  • Support/encourage service operators to improve service compliance
  • Work with WGs on standards-related issues
• Validation:
  • Ensure validators are available (IvoaValidatorsSummary)
  • Encourage use of validators:
    • on deployed services
    • during standard development
• Communication:
  • Provide forum for discussion of operational issues
  • Host/invite "site reports"
  • Encourage feedback communication between ops services and data providers

• Work with DAL on standards issues:
  • ConeSearch: UCD1+
  • DALI: Sexagesimal markup standards
  • SSA: A couple of Errata suggested
• Push for service metadata improvements:
  • VOUnits, UCDs
• Operations in the cloud
• Security in VO services
  • Encourage TAP validators developers to add checks for sql injection susceptibility
• Authentication as an operational necessity
• User agents used in VO services clients

Radio IG

Solar System IG

EPN-TAP 2.1

• progress in various domains (sort out heliophysics and body-fixed coordinate frames, start small bodies taxonomy)

• Installation tests, mock-up service

• Collect some in planetary science & heliophysics
• start generating more tutorials / education actions

EPN-TAP support in pyvo
