[[http://www.ivoa.net/documents/Notes/TimeSys/20181212/index.html][NOTE-timesysnote-1.1-20181212]] * Worked together with Apps to add this TIMESYS element in VOTable 1.4. [[http://www.ivoa.net/documents/VOTable/20190131/][VOTable1.4 Draft]] * Discussion over "ref" as a mandatory field or optional is now open. This is done in Apps. * A minimum vocabulary needs to be set for the reference position. Action on AN through the TDIG and Semantics mailing lists. * Time Series model * The part of the model describing time is described by the Coordinates model (see Working draft) -- Feedback was given to DMGW on that. * Time Series serialisation * Example built for a time-series of positions http://mail.ivoa.net/pipermail/voevent/2018-November/thread.html * VOEvent: * VOEvent standard up to date with the IVOA document standards (.tex file by BC, http://mail.ivoa.net/pipermail/voevent/2018-December/003226.html) * Next step will be to get the PDF of this version accepted as the official document, possibly with a minor version increment. ---+++++ Issues: * TIMESYS * Discussion over "ref" as a mandatory field or optional is now open. * How to get feedback from preference of data providers? * Time Series model & serialization * Dependance on other models slows the process. * Observed process for other models is not encouraging. * Understanding the limit between model and serialization is not straight forward. What goes where? Need to see both model and serializations to understand if all the information needed is existing somewhere. * Need to have some serialization examples based on VO-DML (at least first attempts). Who is doing that? * Serialization based on utypes: list of utypes needs to be built (last interop some mistakes were found) and shared with the TDIG.
