Hi Maxime, I continue to chew through the examples, last night had an insight as to the usefulness of the "FoI-Specific ObsProps" I'd be thankful if you could confirm. Looking at example B.3 apartment 134, I started to get the impression that the reason for the "FoI-Specific ObsProps" is to create a link between a Sensor and the FoI it's observing. In OMS, I'd indicate this through an ObservingCapability object (describes a potential Observation that could be made with a setup of Sensors, Platforms etc). Is this the logic behind this approach? Also - you mention you'd described this in a GitHub issue, but I fear I couldn't find - do you have a pointer for me? :) Kathi On 04.10.2024 10:45, Maxime Lefrançois wrote: > Dear all, > > I agree with promoting, by default, neutral ObsProps in examples > A specific section could introduce FoI-Specific ObsProps and > motivatetheir existence through the corner cases (that are not so > uncommon, arguments are given in the related issue on github) > > Best regards, > Maxime Lefrançois > Associate Professor > IMT - MINES Saint-Étienne - Institut Henri Fayol > Member of Laboratoire LIMOS - UMR CNRS 6158 > > ------------------------------------------------------------------------ > *De: *"Grellet Sylvain" <S.Grellet@brgm.fr> > *À: *"Nicholas Car" <nick@kurrawong.ai>, "Kathi Schleidt" > <kathi@datacove.eu> > *Cc: *"Rob Atkinson" <ratkinson@ogc.org>, "Luís Moreira de Sousa" > <luis.moreira.de.sousa@tecnico.ulisboa.pt>, "Robert Warren" > <warren@glengarryag.com>, "SDW WG" <public-sdw-wg@w3.org> > *Envoyé: *Vendredi 4 Octobre 2024 10:39:33 > *Objet: *RE: Notation Question in the examples on SOSA/SSN > > Bonjour everyone, > > I’d tend to favour « neutral ObsProps » > > I’m not saying that "FoI-Specific ObsProps" don’t exist , pretty sure > we can find edge cases. > > But promoting through example « "FoI-Specific ObsProps" » tend to bias > the re-user approach. > > One recent example here : in our national research infrastructure on > earth and its environnement someone starting to fill in the semantic > backbone did it on a pure thesaurus / keyword way starting from GCMD. > > That’s how we end having Nitrate as a narrower of OceanChemistry… > > As we all know Nitrate is not specific of the Ocean. > > Now, we have to disambiguate the whold thing… > > Favouring « neutral ObsProp » will help exchange observations accross > data silos. > > A bientôt > > Sylvain > > *De :*Nicholas Car <nick@kurrawong.ai> > *Envoyé :* jeudi 3 octobre 2024 16:13 > *À :* Kathi Schleidt <kathi@datacove.eu> > *Cc :* Rob Atkinson <ratkinson@ogc.org>; Luís Moreira de Sousa > <luis.moreira.de.sousa@tecnico.ulisboa.pt>; Robert Warren > <warren@glengarryag.com>; SDW WG <public-sdw-wg@w3.org> > *Objet :* Re: Notation Question in the examples on SOSA/SSN > > Hi all, > > I am watching with interest to see what the consensus is regarding > "FoI-Specific ObsProps" or "neutral ObsProps". > > I'm happy to assist with RDF formulation of things if needed.
