Hi all, Note that the minutes of the Spatial Data on the Web Interest Group meeting at TPAC two weeks ago are available at: - Day 1: https://www.w3.org/2018/10/22-sdw-minutes.html - Day 2: https://www.w3.org/2018/10/23-sdw-minutes.html Thanks to everyone involved! On top of discussions on a number of topics, the group took a few resolutions during the meeting: 1. On CityJSON: In principal, the Spatial Data on the Web IG strongly supports the need to create a feedback loop between practical experience implementing a spec and its design to create effective standards implemented by the wider community. The SDW IG will work on a formal response on CityGML v3 raising technical concerns to be sent to the tc-discuss OGC list. https://www.w3.org/2018/10/22-sdw-minutes.html#x06 2. SSN: Publish the SSN Extensions draft as First Public Working Draft (once editorial fixes are in) https://www.w3.org/2018/10/23-sdw-minutes.html#x03 3. SSN: After checking with other SSN editors, add an hasProperty property to the SOSA namespace, with an "ssn:hasProperty owl:equivalentProperty sosa:hasProperty" axiom, and "ssn:hasProperty owl:propertyChainAxiom ( [ owl:inverseOf sosa:hasFeatureOfInterest ] sosa:observedProperty )" as errata change https://www.w3.org/2018/10/23-sdw-minutes.html#x05 ... but note discussion is still on-going in: https://github.com/w3c/sdw/issues/1006 4. SSN: Re. #1022, we will not add an inverse property for ssn:hasSubSystem, because this would introduce a normative change, and can be done in one's own applications https://www.w3.org/2018/10/23-sdw-minutes.html#x06 5. Time Ontology: Re #987, we will not make any change to the Time Ontology on the basis that the aim of the Time ontology was to ensure backward compatibility with existing implementations. https://www.w3.org/2018/10/23-sdw-minutes.html#x08 6. Time Ontology: Re. #988, it introduces a useful requirement to introduce recurring instants, but addition to the OWL Time ontology would require re-chartering the group. The Interest Group is not planning on working on this feature for now, but would welcome an extension proposal. https://www.w3.org/2018/10/23-sdw-minutes.html#x09 Francois.
