mappings (COLORS_NODES)

What it is​

A module-level mapping of ontology term URIs to color values (hex strings or named colors). Intended for consistent node coloring (e.g., in graph/visualization contexts).

Public API​

  • COLORS_NODES: dict[str, str]
    • Maps an ontology class/term URI to a color value.
    • Values are CSS-like color strings (e.g., "#f61685", "white", "grey", "black").

Configuration/Dependencies​

  • No external dependencies.
  • No configuration required.

Usage​

from naas_abi_marketplace.applications.naas.mappings import COLORS_NODES

uri = "http://ontology.naas.ai/abi/Product"
color = COLORS_NODES.get(uri, "#000000")  # fallback if unknown
print(uri, color)

Caveats​

  • Keys are exact URI strings; lookups are case- and character-sensitive.
  • Some values are named colors (e.g., "white", "grey", "black") rather than hex codes; ensure your renderer supports both.
