Hi all, adding Paul Hershberg as Mr. TSML as a lot of this discussion is circling around TSML. There is an activity underway to update TSML to 2.0, taking the recent updates on both OMS and Coverage models into account, should be linked to whatever goes down here :) Kathi On 13.06.2024 20:10, Grellet Sylvain via Hydro.dwg wrote: > > Ø/that includes key waterml2 domain details that are not included in > TimeseriesML as an informative annex. / > > I’d rather keep those extra WaterML2.0 domain details handled in the > HydroDWG (thus WaterML2.0 line) unless > > -they are very generic (not so waterish afte rall) > > -we just have 1 or 2 of them (to avoir proliferation of specs as well) > > If we end-up with having no need for creating water specific Class & > al. what we could do would rather be turn WaterML2.0 Part 1 – > TimeSeries into a Best Practice document explaining how to use TSML > for quantitative water data. > > That’s exactly the road the Water Quality IE will suggest : everything > covered in OMS, no need for extra-formal specs rather document how to > use it for Water Quality Data to ease the uptake. > > Sylvain > > *De :* Blodgett, David L <dblodgett@usgs.gov> > *Envoyé :* jeudi 13 juin 2024 19:34 > *À :* Rob Atkinson <ratkinson@ogc.org>; Kyle Onda <konda@lincolninst.edu> > *Cc :* Grellet Sylvain <S.Grellet@brgm.fr>; Hydro.dwg@lists.ogc.org; > Schaaf, Hylke van der <hylke.vanderschaaf@iosb.fraunhofer.de>; SDW WG > (public-sdw-wg@w3.org) <public-sdw-wg@w3.org>; Simon Cox <scox@ogc.org> > *Objet :* RE: [EXTERNAL] Re: [Hydro.dwg] json waterml2 / timeseriesml? > > Thanks for the dialogue on this.
