Lecture to ENSG – mastère GDM – 2023-01-20 The 1st presentation (1_Setting_the_scene_final_Grellet.pdf) lays the bases on interoperability to explain why we need interoperability : - Harmonization of water observations data standards - The need for standards - Linked data registries and vocabularies - Data quality & interoperability thanks to semantics : this explains why do we need interoperability with geoscience example, space example and research example and after dream goal and interoperability The document "2_INSPIRE_FAIR_principles_final_Grellet" explains: - INSPIRE implementing rules : Discovery service, View service and Download service) - FAIR principes : “Findble” - “Accessible” - “Interoperable” - “Reusable” - Hindsight on those dynamics The 3rd document presents the interoperability toolbox : - Interoperability Challenges - Standardisation of exchange methods - Standardisation of content exchanged - Semantic interoperability (UML, Semantic Web approaches) Different logic and/or conceptual models are presented : GEOSCIML - GROUNDWATERML2 - SURFACE HYDROLOGY FEATURES - EARTHRESOURCEML - OBSERVATIONS, MEASUREMENTS & SAMPLES. Then you can discover semantic Web approaches - Technical interoperability (Through Webservices / API, Direct access to a resource) The subject of this 4th document is to get to know : - Observations, measurements and samples - OGC SensorThings API Part 1 There are several examples of observations, measurements and samples. After you will find information about OGC SensorThings API : context, data model, REST API, Marine example, Agronomy example, GroundWater example, client side The 5th presentation shows how to put all this together in a project. - Interoperable / FAIR data in a project : How ? - The FAIR ecosystem - Integration in a project with examples - Environmental observation use case - overview (The reference point: Observations & Measurements(O&M), RESTfulAPI implementingO&M : SensorThingsAPI, W3C Ontology«inspiredfrom» O&M» : SSN / SOSA) - Environmentalobservation use case with vocabularies - OMS level 1 and level 2 examples : surface water quantity - EPOS : Multi-standards integration in an Enterprise Architect (EA) project
