Data Model: Enhance selection rules for selecting alternative product classes #145

Open tangobravo62 opened 3 years ago

tangobravo62 commented 3 years ago

Currently the following cannot be modelled with prosEO's selection rules: (1) Find a product of class A with selection policy X (2) Failing that, find a product of class B with selection policy Y

Alternatives are only possible within a single product class (i. e. "Find a product of class A using selection policy X, failing that use selection policy Y").

The Rule Language and the implementation of the selection rules shall be changed to cover the use case described above, in line with the description of input alternatives in the Generic IPF Interface Specifications (MMFI-GSEG-EOPG-TN-07-0003, V1.8, sec. 4.1.3, p. 30).
