FSK to metadata

The "FSK to metadata"-node extracts the metadata of an FSK object (e.g., FSKX-model) to a KNIME JSON table. The FSK object can be created using the “FSK Creator”-node or “FSK Editor”-node (both are available in the FSK-Lab library). The FSK object includes metadata schema that shows a hierarchical structure with four top-level elements:

• (1) general information,
• (2) scope,
• (3) data background,
• and (4) mathematical model and data (so called "Model math").

Each top-level element is saved in a separate JSON column. KNIME JSON nodes can process the columns contain JSON objects , e.g. to show metadata on the KNIME Server. Note that the JSON table describes the metadata of only one model and therefore, needs one row.

Additional information about the metadata structure can be found in Haberbeck et al., 2018, Microbial Risk Analysis, doi:10.1016/j.mran.2018.06.001 or the online version of the metadata schema available at https://goo.gl/PE4ysP.
