v1.7.0

Array Support

The 1.7.x series of LinkML sees the introduction of first-class array support through the introduction of the linkml:array metamodel slot.

Basic example of usage, to define a 3D array:

TemperatureDataset:
    attributes:
      temperature_matrix:
        range: float
        unit:
         ucum_code: K
        array:
          exact_number_dimensions: 3

Individual axes can be named and constrained. See #181 for a log of discussions. Additional documentation will be added to the main LinkML site.
