111 ## See Text::Tradition::Collation for more on text collation itself
115 Text::Tradition is a library for representation and analysis of collated
116 texts, particularly medieval ones. A 'tradition' refers to the aggregation
117 of surviving versions of a text, generally preserved in multiple
118 manuscripts (or 'witnesses'). A Tradition object thus has one more more
119 Witnesses, as well as a Collation that represents the unity of all versions
126 Creates and returns a new text tradition object. The following options are
133 =item B<name> - The name of the text.
137 Initialization based on a collation file:
141 =item B<input> - The input format of the collation file. Can be one of the
146 =item * Self - a GraphML format produced by this module
148 =item * CollateX - a GraphML format produced by CollateX
150 =item * CTE - a TEI XML format produced by Classical Text Editor
152 =item * JSON - an alignment table in JSON format, as produced by CollateX and
155 =item * TEI - a TEI parallel segmentation format file
157 =item * Tabular - a spreadsheet collation. See the documentation for
158 L<Text::Tradition::Parser::Tabular> for an explanation of additional options.
162 =item B<file> - The name of the file that contains the data. One of 'file'
163 or 'string' should be specified.
165 =item B<string> - A text string that contains the data. One of 'file' or
166 'string' should be specified.
170 Initialization based on a list of witnesses [NOT YET IMPLEMENTED]:
174 =item B<witnesses> - A reference to an array of Text::Tradition::Witness
175 objects that carry the text to be collated.
177 =item B<collator> - A reference to a collation program that will accept
184 Return the Text::Tradition::Witness objects associated with this tradition,
187 =head2 B<witness>( $sigil )
189 Returns the Text::Tradition::Witness object whose sigil is $sigil, or undef
190 if there is no such object within the tradition.
192 =head2 B<add_witness>( %opts )
194 Instantiate a new witness with the given options (see documentation for
195 Text::Tradition::Witness) and add it to the tradition.
197 =head2 B<del_witness>( $sigil )
199 Delete the witness with the given sigil from the tradition. Returns the
200 witness object for the deleted witness.
