Assumptions

All othermeta is at the root level in the maps not at the topic ref level

There are 138 maps that have othermeta in them. For at least one of them this assumption is not true, see: help/bundle_setup/setup.ditamap

Name

Data::Edit::Xml::Xref - Cross reference Dita XML, match topics and ameliorate missing references.

Synopsis

Check the references in a large corpus of Dita XML documents held in folder inputFolder running processes in parallel where ever possible to take advantage of multi-cpu computers:

  use Data::Edit::Xml::Xref;

  my $x = xref(inputFolder              => q(in),
               maximumNumberOfProcesses => 512,
               fixBadRefs               => 1,
               flattenFolder            => q(out2),
               matchTopics              => 0.9,
              );

The cross reference analysis can be requested as a status line:

  ok nws($x->statusLine) eq nws(<<END);
Xref: 108 references fixed, 50 bad xrefs, 16 missing image files, 16 missing image references, 13 bad first lines, 13 bad second lines, 9 bad conrefs, 9 duplicate topic ids, 9 files with bad conrefs, 9 files with bad xrefs, 8 duplicate ids, 6 bad topicrefs, 6 files not referenced, 4 invalid guid hrefs, 2 bad book maps, 2 bad tables, 1 External xrefs with no format=html, 1 External xrefs with no scope=external, 1 file failed to parse, 1 href missing
END

Or as a tabular report:

  ok nws($x->statusTable) eq nws(<<END);
Xref:
    Count  Condition
 1    108  references fixed
 2     50  bad xrefs
 3     16  missing image files

 5     13  bad first lines
 6     13  bad second lines
 7      9  files with bad conrefs
 8      9  bad conrefs
 9      9  files with bad xrefs
10      9  duplicate topic ids
11      8  duplicate ids
12      6  bad topicrefs
13      6  files not referenced
14      4  invalid guid hrefs
15      2  bad book maps
16      2  bad tables
17      1  href missing
18      1  file failed to parse
19      1  External xrefs with no format=html
20      1  External xrefs with no scope=external
END

Add navigation titles to topic references

Xref will create or update the navigation titles navtitles of topic refs appendix|chapter|topicref in maps if requested by both file name and GUID reference:

  addNavTitle => 1

Reports of successful updates will be written to:

  reports/good/navTitles.txt

Reports of unsuccessful updates will be written to:

  reports/bad/navTitles.txt

Fix bad references

It is often desirable to ameliorate unresolved Dita href attributes so that incomplete content can be loaded into a content management system. The:

  fixBadRefs => 1

attribute requests that the:

 conref and href

attributes be renamed to:

 xtrf

if the conref or href attribute specification cannot be resolved in the current corpus.

If the fixedFolder attribute is set, the fixed files are written into this folder, else they are written back into the inputFolder. Two reports are generated by this action:

  reports/bad/fixedRefs.txt

  reports/bad/fixedRefsNoAction.txt

This feature designed by mailto:mim@cpan.org.

Deguidize

Some content management systems use guids, some content management systems use file names as their means of identifying content. When moving from a guid to a file name content management system it might be necessary to replace the guids representing file names with the actual underlying file names. If the

  deguidize => 1

parameter is set to true, Xref will replace any such file guids with the underlying file name if it is present in the content being cross referenced.

File flattening

It is often desirable to flatten or reflatten the topic files in a corpus so that they can coexist in a single folder of a content management system without colliding with each other.

The presence of the input attribute:

 flattenFolder => folder-to-flatten-files-into

causes topic files to be flattened into the named folder using the GBStandard to generate the flattened file names. Xref will then update all Dita references to match these new file names. If the flattenFolder folder is the same as the inputFolder then the input files are flattened in place.

Locating relocated files

File references in conref or hrefs that have a unique valid base file name and an invalid path can be fixed by setting the input attribute:

 fixRelocatedRefs => 1

to a true value to request that Xref should replace the incorrect paths to the unique bases file names with the correct path.

If coded in conjunction with the fixBadRefs input attribute this will cause Xref to first try and fix any missing xrefs, any that still fail to resolve will then be ameliorated by moving them to the xtrf attribute.

Fix Xrefs by Title

Dita xref tags with broken or missing href attributes can sometimes be fixed by matching the text content of the xref with the titles of topics.

If:

  fixXrefsByTitle => 1

is specified, Xref will locate possible targets for a broken href by matching the white space normalized Data::Table::Text::nws of the text content of the xref with the similarly normalized title of each topic. If a single matching candidate is located then it will be used to update the href attribute of the xref.

Fix References in Dita To Dita Conversions

When converting a Dita input source corpus to Dita the referenced topics are usually renamed and flattened via the GBStandard. If enabled:

  fixDitaRefs => targets/

updates valid Dita references in the input corpus with the latest name for the referenced topic to make links that were valid in the input corpus valid in the output corpus as well.

The targets/ folder should contain the same set of file names as the original input corpus, each such file should contain the name of a bookmap topic present in the inputFolder= whose chapter and topicrefs identify the new names of the files cut out and flattened from the existing input corpus.

The creation of the target/ folder is usually done by some other piece of software such as Data::Edit::Xml::To::Dita as it is too complex and laborious to be performed reliably by hand. No validation of the contents of this folder is performed as it is assumed that it has been created reliably in software.

Topic Matching

Topics can be matched on title and vocabulary to assist authors in finding similar topics by specifying the:

  matchTopics => 0.9

attribute where the value of this attribute is the confidence level between 0 and 1.

Topic matching produces the reports:

  reports/lists/similar/byTitle.txt
  reports/lists/similar/byVocabulary.txt

Topic matching might take some time for large input folders.

Title matching

This report can be found at:

  reports/lists/similar/byTitle.txt

Title sorts topics by their titles so that topic with similar titles can be easily located:

Create test data

Create files to test the various capabilities provided by Xref

Data::Edit::Xml::Xref Definition

Attributes used by the Xref cross referencer.

Input fields

addNavTitles - If true, add navtitle to outgoing bookmap references to show the title of the target topic.

changeBadXrefToPh - Change xrefs being placed in M3 by fixBadRefs to ph.

deguidize - Set true to replace guids in dita references with file name. Given reference g1#g2/id convert g1 to a file name by locating the topic with topicId g2. This requires the guids to be genuinely unique. SDL guids are thought to be unique by language code but the same topic, translated to a different language might well have the same guid as the original topic with a different language code: =(de|en|es|fr). If the source is in just one language then the guid uniqueness is a reasonable assumption. If the conversion can be done in phases by language then the uniqueness of guids is again reasonably assured. Data::Edit::Xml::Lint provides an alternative solution to deguidizing by using labels to record the dita reference in the input corpus for each id encountered, these references can then be resolved in the usual manner by Data::Edit::Xml::Lint::relint.

fixBadRefs - Try to fix bad references in these files where possible by either changing a guid to a file name assuming the right file is present in the corpus being scanned and deguidize has been set true or failing that by moving the failing reference to the xtrf attribute i.e. placing it in M3 possibly renaming the tag to ph if changeBadXrefToPh is in effect.

fixDitaRefs - Fix references in a corpus of Dita documents that have been converted to the GB Standard and whose target structure has been written to the named folder.

fixRelocatedRefs - Fix references to topics that have been moved around in the out folder structure assuming that all file names are unique.

fixXrefsByTitle - Try to fix invalid xrefs by the Gearhart Title Method if true

flattenFolder - Files are renamed to the Gearhart standard and placed in this folder if set. References to the unflattened files are updated to references to the flattened files. This option will eventually be deprecated as the Dita::GB::Standard is now fully available allowing files to be easily flattened before being processed by Xref.

inputFolder - A folder containing the dita and ditamap files to be cross referenced.

matchTopics - Match topics by title and by vocabulary to the specified confidence level between 0 and 1. This operation might take some time to complete on a large corpus.

maxZoomIn - Optional hash of names to regular expressions to look for in each file

maximumNumberOfProcesses - Maximum number of processes to run in parallel at any one time with a sensible default.

printSummaryLine - Print the summary line if true - on by default.

reports - Reports folder: the cross referencer will write reports to files in this folder.

requestAttributeNameAndValueCounts - Report attribute name and value counts

Output fields

allowUniquePartialMatches - Allow unique partial matches - i.e ignore the stuff to the right of the # in a reference if doing so produces a unique result. This feature has been explicitly disabled for conrefs (PS2-561) and might need to be disabled for other types of reference as well.
