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)
