Metadata-Driven Similarity Conversion

You can migrate legacy similarity calculators to a metadata-driven framework using a dual-path implementation strategy that prioritizes metadata-driven calculations while falling back to legacy pattern-based approaches for backward compatibility. This allows gradual migration without breaking existing functionality.

A metadata-first approach for similarity calculation logic prioritizes using defined metadata, such as resistance and tolerance values, to compute matches. It falls back to legacy pattern-based approaches only when the required metadata is unavailable, ensuring non-metadata-aware systems continue to function.

Yes, you can convert similarity calculators to metadata-driven one at a time. The dual-path implementation strategy enables gradual migration by maintaining backward compatibility, allowing you to update individual calculator classes without breaking existing functionality.

Updating similarity calculator classes involves adding necessary imports, modifying the calculateSimilarity method to implement metadata-driven logic, adding spec extraction helpers, and updating test assertions to use threshold comparisons for more robust validation.

You update test assertions for metadata-driven similarity calculations by switching to threshold comparisons. This provides more robust validation than exact pattern-based matching when verifying the updated calculateSimilarity method and spec extraction helpers.

You should use a dual-path implementation strategy for similarity calculator migration because it ensures backward compatibility and gradual adoption. It prioritizes metadata-driven calculations while providing a fallback to legacy methods, preventing system breakage during the migration process.
