Agenda

• From April 2021 Cos4Cloud sponsors the continuation of the CoP
  
  • Use cases for CitSciIE2 with STAplus: SecDim -FROST extension, Pl@antnet STA service (important conclusions on how to optimize the database indexing to accelerate responses), FASTCAT usage of STA, MOBIS, Nat2STA
• OGC Members meeting TODAY:
  • 121st Meeting - December 2021 (North America) registration is open: https://na.eventscloud.com/website/30705/
    • SensorThings SWG session on 1st December at 16:30 CET: OGC Best Practice for using SensorThings API with Citizen Science by Andreas Matheus, Joan Masó Pau
• Progress report on STAplus implementation
  • Technical interoperability
  • Semanic interoperability
• Discussion about ER writing

Minutes

• Lucy presented her activities on low cost sensors for schools.
  • Her experience with low cost sensors for air quality so far is not good.
  • She finds the situation intersting because it enphasices the need for provenance and data quality information associated to measures.
  • This makes the excercice with schools more rich and interesting. She wants to test the sensor community kits.
  • The separation of the platform (thing) the sensor and the variable (observed property) is needed and STA already has it.
  • Discussion on how to use STA for hourly averages "instead of" or "in addition to" the raw data.
• Joan wanted to discuss the convenience to extend API model to include DQ_element in DataStream or in Group. currently it is only in observation, limiting the applicability of data quality to individual observations but and not to overall summaries.
• Andreas was interested in discussing if observatinos can be edited and by whom.
  • There are obvious cases where it is done in practice when the series is recalibrated. Is this a new observation or an edit.
  • Need to record When, who and why the observation changed. Blockchain technologies are good at recoding this.
• Kaori discussed on mapping Darwin Core and STA.
  • Where and how the taxon should be recorded?
    • Alternative A: Taxonomies could be considered observations and they could be related to the actual observations
    • Alternative B: The observed taxon could be encoded as a URI result that points to the full description of the taxon
    • Alternative C: "Relation" should allow for linking to external resources and taxon coudl be one of them. It seems the prefered alternative but this will requere edititng the STAplus data model.
• Andreas is pushing the best practices document and requested Joan to contribute to a section that is indicated.

Regular topics on these meetings

• Regular topics on these meetings
• • Progress on implementations of STAplus services and clients (Cos4Cloud)
    • Henning Bredel to demonstrate the 52North demo server: https://github.com/52North/sensorweb-server-sta/tree/feature/sta-plus/dao-citsci/docs
    • Andreas (SecureDimensions) has implemented the data cloud deployed by EGI, EOSC service provider: https://cos4cloud.secd.eu/staplus/v1.1/api (for Cos4Cloud project)
      • Joan (CREAF) has written the script to test exporting data from the Natusfera to the STAplus: https://github.com/joanma747/Natusfera4STAplus
        • Natusfera in JSON: https://natusfera.gbif.es/observations/313411.json
        • STAplus in JSON: https://cos4cloud.secd.eu/staplus/v1.1/Groups?$filter=name%20eq%20%27http://natusfera.gbif.es/observations/313411%27&$select=name,description,created,Observations,id&$expand=Observations($select=resultTime,result,phenomenonTime,parameters,FeatureOfInterest,Datastream;$expand=Datastream($select=Party,Sensor,Thing,License,ObservedProperty;$expand=Party($select=nickName),Sensor($select=name),Thing($select=name),License($select=name),ObservedProperty($select=name)),FeatureOfInterest($select=feature/geometry/coordinates))
      • Inria, one of the Cos4Cloud partners, has tested performance levels by exporting data (7 million records) from their Pl@ntNet to the STAplus, and will be testing to improve indexing in the database with Andreas: DB Performance | FROST-Server Documentation (fraunhoferiosb.github.io)
      • Next step will require semantic interoperability (e.g. RDF from W3C) between those different data models (e.g. Natusfera, Pl@ntNet) applied to the STAplus model using the entity 'Relation'. An RDF query language such as SPARQL can be used then. Relation may play a critical role to explain taxonomy used in the biodiversity domain model.
        • Kaori (CREAF) will explore modelling Darwin Core in the STAplus, which can be applicable to other platforms on the biodiversity domain (e.g. GBIF format), to increase semantic interoperability using 'Relation' explaining taxonomic hierarchy (e.g. RDF format)
