=head1 NAME

korapxml2krill - Merge KorapXML data and create Krill documents


=head1 SYNOPSIS

  $ korapxml2krill -z --input <directory> --output <filename>
  $ korapxml2krill archive -z --input <directory> --output <directory>
  $ korapxml2krill extract --input <directory> --output <filename> --sigle <SIGLE>


=head1 DESCRIPTION

L<KorAP::XML::Krill> is a library to convert KorAP-XML documents to files
compatible with the L<Krill|https://github.com/KorAP/Krill> indexer.
The C<korapxml2krill> command line tool is a simple wrapper to the library.


=head1 INSTALLATION

The preferred way to install L<KorAP::XML::Krill> is to use L<cpanm|App::cpanminus>.

  $ cpanm https://github.com/KorAP/KorAP-XML-Krill

In case everything went well, the C<korapxml2krill> tool will
be available on your command line immediately.


=head1 ARGUMENTS

=over 2

=item B<archive>

Process an archive as a Zip-file or a folder of KorAP-XML documents.

=item B<extract>

Extract KorAP-XML files from a Zip-file.

=head1 OPTIONS

=over 2

=item B<--input|-i> <directory|file|files>

Directory or archive file of documents to convert.

Archiving supports multiple input archives with the constraint,
that the first archive listed contains all primary data files
and all meta data files.

  -i file/news.zip -i file/news.malt.zip -i #file/news.tt.zip

(The directory structure follows the base directory format,
that may include a C<.> root folder.
In this case further archives lacking a C<.> root folder
need to be passed with a hash sign in front of the archive's name.)

=item B<--output|-o> <directory|file>

Output folder for archive processing or
document name for single output (optional),
writes to C<STDOUT> by default
(in case C<output> is not mandatory due to further options).

=item B<--overwrite|-w>

Overwrite files that already exist.

=item B<--token|-t> <foundry>[#<file>]

Define the default tokenization by specifying
the name of the foundry and optionally the name
of the layer-file. Defaults to C<OpenNLP#tokens>.

=item B<--skip|-s> <foundry>[#<layer>]

Skip specific annotations by specifying the foundry
(and optionally the layer with a C<#>-prefix),
e.g. C<Mate> or C<Mate#Morpho>. Alternatively you can skip C<#ALL>.
Can be set multiple times.

=item B<--anno|-a> <foundry>#<layer>

Convert specific annotations by specifying the foundry
(and optionally the layer with a C<#>-prefix),
e.g. C<Mate> or C<Mate#Morpho>.
Can be set multiple times.

=item B<--primary|-p>

Output primary data or not. Defaults to C<true>.
Can be flagged using C<--no-primary> as well.
This is I<deprecated>.

=item B<--jobs|-j>

Define the number of concurrent jobs in seperated forks
for archive processing.
Defaults to C<0> (everything runs in a single process).
This is I<experimental>.

=item B<--meta|-m>

Define the metadata parser to use. Defaults to C<I5>.
Metadata parsers can be defined in the C<KorAP::XML::Meta> namespace.
This is I<experimental>.

=item B<--pretty|-y>

Pretty print JSON output. Defaults to C<false>.
This is I<deprecated>.

=item B<--gzip|-z>

Compress the output.
Expects a defined C<output> file in single processing.

=item B<--cache|-c>

File to mmap a cache (using L<Cache::FastMmap>).
Defaults to C<korapxml2krill.cache> in the calling directory.

=item B<--cache-size|-cs>

Size of the cache. Defaults to C<50m>.

=item B<--cache-init|-ci>

Initialize cache file.
Can be flagged using C<--no-cache-init> as well.
Defaults to C<true>.

=item B<--cache-delete|-cd>

Delete cache file after processing.
Can be flagged using C<--no-cache-delete> as well.
Defaults to C<true>.

=item B<--sigle|-sg>

Extract the given text sigles.
Can be set multiple times.
I<Currently only supported on C<extract>.>
Sigles have the structure C<Corpus>/C<Document>/C<Text>.

=item B<--log|-l>

The L<Log4perl> log level, defaults to C<ERROR>.

=item B<--help|-h>

Print this document.

=item B<--version|-v>

Print version information.

=head1 ANNOTATION SUPPORT

L<KorAP::XML::Krill> has built-in importer for some annotation foundries and layers
developed in the KorAP project that are part of the KorAP preprocessing pipeline.
The base foundry with paragraphs, sentences, and the text element are mandatory for
L<Krill|https://github.com/KorAP/Krill>.

More importers are in preparation.
New annotation importers can be defined in the C<KorAP::XML::Annotation> namespace.
