Constructor Details

#initialize(pub, ref_index = {}, errors = {}, tc_index = {}, amend_index = {}, date_index = {}) ⇒ DataParser

Returns a new instance of DataParser.

Parameters:

  • pub (Hash) —

    one Open Data record

  • ref_index (Hash{Integer=>String}) (defaults to: {}) —

    map of Open Data ‘id` -> `reference`, used to resolve `replaces` / `replacedBy` (which are numeric IDs in the source).

  • errors (Hash) (defaults to: {}) —

    error accumulator (‘Hash.new(true)`); fields are AND-ed across all records by the `report_errors` machinery.

  • tc_index (Hash{String=>Hash}) (defaults to: {}) —

    map of TC/SC reference -> ‘{ “en” => title, “fr” => title }`, used to resolve the human committee label from the Open Data technical-committees dataset.

  • amend_index (Hash{String=>Array<String>}) (defaults to: {}) —

    map of base reference -> list of supplement (Amd/Cor/Add) references that target it. Open Data records the supplement -> base direction only via the reference string, so we pre-build the reverse map.

  • date_index (Hash{String=>String}) (defaults to: {}) —

    map of reference -> ‘publicationDate`, used to attach a `published` date to each emitted relation’s bibitem when the related document is itself present in the Open Data feed.
