Discussion items
Running DataCat / forms @ncsa
- NCSA is an open site, we can bring and run (secure) software
- need to standardize deployment of services like that
- not committed to maintaining existing paths (urls), MetaServ needs to hide them behind a layer
- hooking up DataCat with LDAP - makes most sense to connect it with LSST LDAP managed by Iain. Jacek will follow up
MetaServ & Butler
- use case: users will need to run with no mysql connectivity to central server, so we have to support simple sqlite too
SLAC/ NCSA responsibilities
- anything science related - SLAC
- details of storage hierarchy, replication, checksums, hardware layout, backups etc - NCSA
- gray area: services developed at slac might rely on info stored by NCSA layer (eg is the file on tape or disk)
VMs
- IPAC needs few VMs @NCSA in the near future
- for now: provision manually
- Xiuqin will write down needs
API for cutout service
- Brian's experience: python is easier if it is first experience. If need performance java is better, it has great parsing libraries, serializing/deserializing different formats in java is convenient. Django is fine for small applications. Framework "flask" is good too.
- Ruby? Great to get started. Issues with performance, not best in long run.
- fits libraries we rely on: afw, easily accessible from python
- looks like python is a good choice for us
- but check with Serge Monkewitz, he used it for IRSA, wasn't happy with some parts
- be consistent, use the same API for all services
DDT for qserv-served tables?
- proper solution coming in S15
- for now, use the tables that are maintained for schema browser
User upload tables
- come up with a plan during S15
Dataset/repo terminology
- IPAC todo from past meetings, IPAC team will look into it
No meeting next week, it i a holiday at most labs.
