| ### converts input in TEI P5 format (https://www1.ids-mannheim.de/kl/projekte/korpora/textmodell.html) |
| ### into output in KorAP-XML format (https://github.com/KorAP/KorAP-XML-Krill -> 'KorAP-XML document') |
| ### |
| ### input restrictions: |
| ### |
| ### . utf8 encoded |
| ### . TEI P5 formatted input with certain restrictions: |
| ### . mandatory: text-header with integrated textsigle, text-body |
| ### . optional: corp-header with integrated corpsigle, doc-header with integrated docsigle |
| ### |
| ### . all tokens inside the primary text (inside $data) may not be newline seperated, because newlines |
| ### are removed (see below: 'inside text body') and a conversion of newlines into blanks between 2 tokens |
| ### could lead to additional blanks, where there should be none (e.g.: punctuation characters like ',' or |
| ### '.' should not be seperated from their predecessor token). |
| ### - see also '~ whitespace handling ~' |
| ### |
| ### . POS and MSD inline annotations handling (see below: expected format) |
| ### ... |
| ### |
| ### notes on the output: |
| ### |
| ### . zip file output (default on stdout) with utf8 encoded entries (which together form the KorAP-XML format) |

| # example: '... <head type="main"><s>Campagne in Frankreich</s></head><head type="sub"> <s>1792</s> ...' |
| # |
| # Two text-nodes should normally be separated by a blank. In the above example, that would be the 2 text-nodes |
| # 'Campagne in Frankreich' and '1792', which are separated by the whitespace-node ' '. |
| # |
| # Assumed, that the above example marks the general case, then the text-node 'Campagne in Frankreich' leads to the |
| # setting of '$add_one' to 1, so that when opening the 2nd 'head'-tag and setting it's from-index, it gets the right |
| # offset, which is the start-index of '1792'. |
| # |
| # To check, that the above consideration holds, we save the from-index of a read whitespace-node into the hash %ws. |
| # By this, it can be checked when closing a tag, if the 'non-tag'-node (text or whitespace) before the last 'non-tag'- |
| # node was actually a whitespace-node ($ws{ $fval - 1 }). |
| # |
| # For whitespace-nodes, also $add_one has to be set to 0, so when opening the next tag (in the above example the 2nd |
| # 's'-tag), no additional 1 is added, because this was already done by the whitespace-node itself (by incrementing the |
| # variable $dl). |
| # |
| # Now, what happens, when 2 text-nodes are not seperated by a whitespace-node (blank)? (e.g.: <w>Augen<c>,</c></w>) |
| # |
| # In this case, the falsely increased from-value has to be decreased again by 1 when closing the referring tag |
| # (...$fval - 1; # recorrect). |
| # |
| # Comparing the 2 examples '<w>fu</w> <w>bar</w>' and '<w>fu</w><w> </w><w>bar</w>' (even though, the 2nd one makes less |
| # sense, because of '<w> </w>'), in both the ' ' is handled as a whitespace-node (XML_READER_TYPE_SIGNIFICANT_WHITESPACE). |
| # |
| # So the from-index of the 2nd w-tag (in the second example) would refer to 'bar', which may not have been the intention |
| # (even, if '<w> </w>' doesn't make a lot of sense). TODO: could this be a bug, which needs to be fixed? |
| # |
| # Empty tags also cling to the next text-token - e.g. in '...<w>tok1</w> <w>tok2</w><a><b/></a><w>tok3</w>...' the from- |

| =head1 NAME |
| |
| tei2korapxml - Conversion of TEI P5 based formats to KorAP-XML |
| |
| =head1 SYNOPSIS |
| |
| cat corpus.i5.xml | tei2korapxml > corpus.korapxml.zip |
| |
| =head1 DESCRIPTION |
| |
| C<tei2korapxml> is a script to convert TEI P5 and I5 based documents |
| |
| to the KorAP-XML format. If no specific input is defined, data is |
| |
| read from C<STDIN>. If no specific output is defined, data is written |
| |
| to C<STDOUT>. |
| |
| This program is usually called from inside another script. |
| |
| =head1 INSTALLATION |
| |
| C<tei2korapxml> requires L<libxml2-dev> bindings to build. When |
| |
| these bindings are available, the preferred way to install the script is |
| |
| to use L<cpanm|App::cpanminus>. |
| |
| $ cpanm https://github.com/KorAP/KorAP-XML-TEI.git |
| |
| In case everything went well, the C<tei2korapxml> tool will |
| |
| be available on your command line immediately. |
| |
| Minimum requirement for L<KorAP::XML::TEI> is Perl 5.16. |
| |
| =head1 OPTIONS |
| |
| =over 2 |
| |
| =item B<--base|-b> |
| |
| The base directory for output. Defaults to C<.>. |
| |
| =item B<--help|-h> |
| |
| Print help information. |
| |
| =item B<--version|-v> |
| |
| Print version information. |
