This section outlines the architectural foundations and scientific data models underlying the Capella Datascience platform.
| Concept | Description |
|---|---|
| NetCDF and NcML Digital Twin | How binary NetCDF datasets are transformed into in-memory EMF NcML 2.2 models for lightweight manipulation and querying. |
| Multi-Dimensional Data & Slicing | The coordinate axes model, dimensionality, shape semantics, and high-performance N-dimensional array slicing. |
| NcML 2.2 Schema & EMF Model | Detailed specification of the NcML 2.2 schema elements (variables, dimensions, attributes, groups) and their EMF representation. |
| THREDDS Catalogs & Services | The hierarchical structure of THREDDS XML catalogs, dataset services (OpenDAP, WMS, WCS), and remote metadata mapping. |
| Remote Data Acquisition & Subsetting | OpenDAP protocol semantics and on-demand remote array slicing across networks and cloud storage. |
| Visualization Configuration Books (.ncconfig) | Architecture of the .ncconfig metamodel for persistent, decoupled visualization styling, palette mappings, and dimension slices. |
| Geospatial Systems & Apache SIS | Coordinate Reference Systems (CRS), EPSG projections, geodetic transformations, and map rasterization with Apache SIS. |
