TrajectPlus

Gem Version

TrajectPlus is a number of useful additions to Traject

Features

New readers:

TrajectPlus::JsonReader

provide 'reader_class_name', 'TrajectPlus::JsonReader'
to_field 'title', extract_json('$.label')

TrajectPlus::CSVReader

provide 'reader_class_name', 'TrajectPlus::CSVReader'
to_field 'title', column('Record Title')

TrajectPlus::XMLReader

provide 'reader_class_name', 'TrajectPlus::XMLReader'
to_field 'title', extract_xml('/*/mods:language/mods:scriptTerm',
                              { 'mods' => 'http://www.loc.gov/mods/v3' })

There are also XML macros for specific formats (MODS, TEI, FGCD):

For example:

to_field 'title', extract_mods('/*/mods:language/mods:scriptTerm')
to_field 'cho_description', extract_tei("/*/tei:teiHeader/tei:fileDesc/tei:sourceDesc/tei:msDesc/tei:msContents/tei:summary")
extract_fgdc('/*/idinfo/citation/citeinfo/geoform')

New macros:

  • transform_values
  • first
  • conditional
  • from_settings
  • match
  • format
  • translation_map
  • accumulate : Streamlines creation of lambdas that need no additional parsing or filtering
to_field 'x', accumulate { |record, context| record.values }
  • copy : Copies values from one output field to another
to_field 'x', copy('y')
  • compose : easy create sub-transformations
compose do
  to_field 'x', accumulate { |record, context| record.x }
end

# => { 'x' => [1, 2, 3]}
compose('subfield') do
  to_field 'x', accumulate { |record, context| record.x }
end

# => { 'subfield' => [{ 'x' => [1, 2, 3]} ]}
compose ->(record, accumulator, context) { record.subfield } do
  to_field 'x', accumulate { |subfield, context| subfield.x }
end
# => { 'x' => [1, 2, 3]}
  • transform, supporting a variety of string methods: 'split', 'concat', 'prepend', 'gsub', 'encode', 'insert', 'strip', 'upcase', 'downcase', 'capitalize'

These can be applied to any extract function:

to_field 'title', extract: extract_xml('title'), transform: transform(gsub: ['|', ' - '])

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
