metadata toolkit

 Catmandu provides a suite of Perl modules
 to ease the import, storage, retrieval, export
 and transformation of metadata records.
 .
 Combine Catmandu modules
 with web application frameworks such as PSGI/Plack,
 document stores such as MongoDB or CouchDB
 and full text indexes as ElasticSearch or Solr
 to create a rapid development environment
 for digital library services
 such as institutional repositories and search engines.
 .
 Use of the debug option
 requires the packages liblog-any-adapter-log4perl-perl
 and liblog-log4perl-perl.
