Josh Lieberman, Will Pozzi, Bill Sonntag, Phil Yang, Stefano Nativi, Brad Lee, Veronica Guidetti
(Yang) GMU participation in USG Clearinghouse development activities
(Pozzi) Coordination of datasets will generate requirements for semantic interoperability; is EDO planning on putting any drought content on the GEO portal?
(Stefano) believes Stefan is considering doing so for Spain.
(Sonntag) Gulf of Maine scenario activity being organized for summer ESIP meeting around shellfish and beach closures from microclimate and water quality data. Discussions with Seattle, Great Lakes and Mediterranean groups as well.
(Veronica) EO2Heaven cholera / water quality scenario. Needs François to discuss. Veronica mentioned WQ projects carried out by ESA at other sites.
(Stefano) Semantic broker for connecting water vocabularies. EuroGEOSS presently connecting drought, biodiversity, and forestry systems by brokering to form a federation. Now adding "augmented discovery component" with vocabulary-based semantic capabilities using GEMET and a multi-lingual GEOSS SBA vocabulary.
(Lee) Using a component from meteorology to validate documents based on ontologies and query vocabularies based on Auscope vocabulary service implementation.
(Lieberman) In order to choose tractable semantic problems to solve, we should work towards a water specialization of a semantic term mapping and discovery use case.
(Pozzi) We have capability in existing water ontology, augmented discovery components which are vocabulary-based, and discovery of datasets by identifying discovery key terms. We have each of the subsystems and can perform some integration for AIP-3 and some for AIP-4. Term discovery service? (Lieberman) Basically a faceted spatial search of resources by keyword terms, extended by semantic inference and mapping.
(Stefano) Will send a description of the EuroGEOSS infrastructure and semantic capability plan. Cristianio is part of JRC / Genesis project which is another similar activity.
(Lieberman) Need to look at what can be done in AIP-3 on three fronts:
(Stefano) Working on extended OpenSearch interface for generating SPARQL queries to derive extended terms then using those terms against CSW federated catalog.
(Pozzi) Datasets are available in US, Spain, etc.We can display existing, current capability of soil moisture maps (for EU) and USA (by Princeton) and for global (Princeton), and a mapping utility can allow users to draw a map around a desired available domain, and have the soil moisture and soil moisture anomaly fields retrieved for that area, with the specified key word (given by user) mapped to terms in the ontology or vocabulary (and from these to the datasets).
(Lieberman) Building the connections from queries of interest to dataset descriptions will be the hard work. Suggestion to post vocabularies on collab site so that they can be utilized in the multiple search /mediation facilities being developed in advance of a GCI capabiility. Should also consider building ontologies to represent the predictive modeling / decision support workflows in the drought and water quality scenarios, so that they also can be referenced in queries and the vocabulary matching capability can be directly connected to the scenarios.
(Lee) Will document and make available the auscope capability and register services in GEOSS to start with enhanced discovery.
(Veronica) Will the system be scalable to other geographic areas?
(Will) Will and Stefano will exchange the scenario to build a common scenario-use case with drought (including DRI and GMU).
