Harmonic.Rules.Import.CSV

Contents

Description

Parses Yale Classical Archives Corpus data from CSV format into typed Haskell records for downstream transformation and graph storage.

Synopsis

Corpus rows

One row of the YCACL artifact exported by scripts/export_ycacl.R.

The CSV carries pitches as a space-separated string in a single column; the FromNamedRecord instance splits and parses that into yrPitches.

Constructors

YCACLRow
Fields yrComposer :: !Text composer name as it appears in the corpus yrPiece :: !Text piece identifier, unique within a composer yrOrder :: !Int position of this slice within the piece yrPitches :: ![Int] pitch classes (0-11) sounding at this slice yrFundamental :: !Int fundamental detected for the slice

Nested corpus map

Composer name, used as the outer key of YCACLData. Case is preserved here; composer matching is case-insensitive and happens downstream.

Piece identifier, unique within one composer.

The whole corpus, grouped composer then piece, with each piece reduced to its ordered list of slices.

Load YCACL artifact (composer, piece, order, pitches, fundamental) into nested maps.
