The following pages are there to gather opinions, feedbacks and proposals for DAL future (see
http://wiki.ivoa.net/internal/IVOA/InteropOct2016DAL/DAL_Future.pdf) . The underlying question is what are the main evolutions of the DAL protocols in a near future (SIA,
SODA, TAP,
ADQL,
DataLink, etc...). The main drivers are:
1 ) CSP priorities : what is achieved and what is not achieved.
2 ) Feedback from implementation of recently recommended protocols (SIA,
DataLink,
SODA, TAP new version)
3 ) Multidimensional data access roadmap as established in october 2013 in Hawaï (fall interop + ADASS).
Properties to consider :
DataType, Functionalities, Software Design, Position in IVOA landscape (see
http://www.adass2016.inaf.it/index.php/participants-all/4-poster/163-molinaro-marco)
* Data Type
Add Time Domain (
HIGHEST Scientific priority: see http://wiki.ivoa.net/twiki/bin/view/IVOA/CSPTimeSeries )
- use cases
- ideas for solutions
- attempts and prototypes reports
* Functionalities
- Feedback : what is missing/inadequate in current protocols
- Extended metadata (for Cubes and Time Domain)
- Extended server side data services (regridding, deconvolution , etc..)
* Software Design
- Interface design
Feedback on current interfaces
Driving extended functionalities
Standard definition of custom services
- Pushing code to the data :
science cases,
attempts and prototypes
- Formats and Languages :
Json,
PQL, PDL, etc...
What to use next ?
* TAP evolution
from relational databases to ...
relaxing
ADQL ?
* Position in IVOA landscape
- Merging DAL protocols, HiPS and MOC
HiPS is also a discovery and access mode: How to marry service approach and
HipS Approach in both ways ?
Querying services by MOC : is that necessary ?
- Data Models
ObsCore,
DataSet Metadata, ND-Cube,
SparseCube ,
STC ??
