3. TD Focus Session Followup
Presentation Comments:
Time Series
Need discovery, access, std serialization & tools
Want <any> vs. Time capability
Data Queries
By: Spectral Types, Classification, period, etc
Tools
To do period determination, filtering, detrending, fit sine funcs,…
Data mining tools
Follow-up or data augmentation, e.g. assoc catalogs/mages
VOEvent
Want to send all info in one packet, avoid callbacks
Need a compact serialization (40 bytes info, 787 bytes XML)

4. TD Focus Session Followup
Panel Discussion Points:
Standards
Implementations lagging stds, need more up-front for adoption
Centralized IVOA code repository
Simple Time Series
Not perfect, but adequate until TS data model complete
Tools
Java vs Python
No good clients for ObsCore
VOEvent
Transient distribution network, unclear who will build it
Scalability of svcs a growing issue, e.g. image archive followup

5. Discussion Provocation
Bulk Transport
The “LSST Problem” (but applies to LOFAR and others)
Query, Storage and Retrieval
Individual subscriptions vary widely
Searches custom to service, not positional, etc
What does a Repository really look like?
Available Toolkits
Can we collect these for the TD community (if they exist)
Is there general purpose software out there?
Infrastructure
Do we really have a backbone?
Could we build a TransientZoo if we wanted to?
Community
What is the Venn diagram of IVOA and Hotwired?
