ESE-ERGO

Objectives

  • Further evolve necessary FedEO software components to improve future data access and exploitation mechanisms:

    • Performance and scalability
    • Widen applicability of solution
  • Review emerging IT solutions, technology trends and adapt to bring benefits to the EO community.
  • Adoption of OpenAPI, also encouraged by OGC, as standard interface for its services, in combination with JSON and JSON-LD
  • Analyse and adopt new international guidelines and standards to improve gateway/catalogue functionalities, performance and interoperability. This includes:

    • Emerging GeoDCAT-AP specification to publish EO metadata
    • OGC 13-026r9 to introduce enhanced functionalities (e.g., flexible string search, results ranking, links to EO external services)
    • OGC 17-047 to provide a JSON-based encoding response from OpenSearch interface (e.g., quicker catalogue response, ease User interface development)
    • Improve faceted search capabilities
  • Transition to an internal metadata model of which other metadata models are views, to allow more flexibility. This includes:

    • Recent OGC guidelines, in cooperation with CEOS/NASA, about collection and product metadata model based on GeoJSON(-LD) encoding (e.g., OGC 17-084, OGC 17-003)
    • Generalization of the concept of catalogue entry in order to consider granules (/products), collections (aggregation of granules/products) and services related to both of them (e.g., remote processing, datacube, etc.) seamlessly (e.g., GeoDCAT-AP, ISO 19115-1 & ISO 19115-3, etc.)

Main Expected Results

The main expected outcomes of the project are:

  • (1) Scalable Catalogue based on:

    • OpenAPI
    • GeoJSON
    • OpenSearch OGC 17-047 and OGC 13-026r9
    • Interconnected metadata for collections, granules and applications (OGC 17-003, OGC 17-084, OGC 19-020r1)
    • Supporting additional response formats (JSON-LD, DCAT, GeoDCAT-AP)
  • (2) Web-based Collection Metadata Editor with validation/DIF-10/GeoJSON support
  • (3) Web-based Access Metrics Application
