Discussion Items

L1 API?

• L1 won't rely on Qserv, so no Qserv-specific extensions, otherwise very similar to Qserv (basically, pure SQL)

Once central entry point

• see SUI HTTP API in the diagrams at LSST External APIs
• equivalent to "web service" described in Delete me
• mostly pass through for lower level primitives
  • don't put authorization/authentication or resource mgmt there
• who owns it?
  • we could define a standard, and each group would do implementation to the standard. Still would need "an owner"
  • to pick an owner, we can look from WBS perspective or who-has-expertise perspective
  • ideally it is a mix of IPAC and SLAC 
  • bring up with Jeff, discuss at next DMLT meeting

VO interfaces

• no good real implementation of ADQL makes it hard
• might need some data in database to well support VO
• lsst needs to start getting involved in VO discussions/groups/meetings
• need lsst VO champion to interface with VO community
• KT will talk to Don
• need VO-related requirements and sample queries
• Xiuqin will create several tickets to cover VO needs (the way ipac understands it)

Meta Store vs L1/L2 Stores

• source of truth: always L1/L2 data stores
• open question: do we need to copy metadata from L1/L2 to metadata store, and transform to make it queryable for VO? Maybe
