       Biber::DataModel - Biber::DataModel objects

   new
           Initialize a Biber::DataModel object
           We are passing in an array of datamodels as there may be more than one in tool
           mode - the one from biber-tool.conf and modifications in a user .conf
           We first merge these before extracting data. In case of conflicts, user .conf
           datamodel takes precedence.

   get_outcase
           Returns the original datamodel field/entrytype case for output

   constants
           Returns array ref of constant names

   get_constant_type
           Returns a constant type

   get_constant_value
           Returns a constant value

   is_multiscript
           Returns boolean to say if a field is a multiscript field

   fieldtypes
           Returns array ref of legal fieldtypes

   datatypes
           Returns array ref of legal datatypes

   is_field
           Returns boolean to say if a field is a legal field.
           Allows for fields with meta markers whose marked field should be in
           the datamodel.

   entrytypes
           Returns array ref of legal entrytypes

   is_entrytype
           Returns boolean to say if an entrytype is a legal entrytype

   is_field_for_entrytype
           Returns boolean to say if a field is legal for an entrytype

   entrytype_is_skipout
           Returns boolean depending on whether an entrytype is to be skipped on output

   get_fields_of_fieldtype
           Retrieve fields of a certain biblatex fieldtype from data model
           Return in sorted order so that bbl order doesn't change when changing
           .bcf. This really messes up tests otherwise.

   get_fields_of_fieldformat
           Retrieve fields of a certain format from data model
           Return in sorted order so that bbl order doesn't change when changing
           .bcf. This really messes up tests otherwise.

   get_fields_of_datatype
           Retrieve fields of a certain biblatex datatype from data model
           Return in sorted order so that bbl order doesn't change when changing
           .bcf. This really messes up tests otherwise.

   get_fields_of_type
           Retrieve fields of a certain biblatex type from data model
           Return in sorted order so that bbl order doesn't change when changing
           .bcf. This really messes up tests otherwise.

   is_fields_of_type
         Returns boolean to say if the given fieldtype/datatype/format is a valid combination

   get_fieldtype
           Returns the fieldtype of a field

   get_datatype
           Returns the datatype of a field

   get_fieldformat
           Returns the format of a field

   get_dm_for_field
           Returns the fieldtype, datatype and format of a field

   field_is_fieldtype
           Returns boolean depending on whether a field is a certain biblatex fieldtype

   field_is_datatype
           Returns boolean depending on whether a field is a certain biblatex datatype

   field_is_type
           Returns boolean depending on whether a field is a certain biblatex fieldtype
           and datatype

   field_is_nullok
           Returns boolean depending on whether a field is ok to be null

   field_is_skipout
           Returns boolean depending on whether a field is to be skipped on output

   check_mandatory_constraints
           Checks constraints of type "mandatory" on entry and
           returns an arry of warnings, if any

   check_conditional_constraints
           Checks constraints of type "conditional" on entry and
           returns an arry of warnings, if any

   check_data_constraints
           Checks constraints of type "data" on entry and
           returns an array of warnings, if any

   check_datatypes
           Checks datatypes of fields against fields. These are not explicit constraints
           in the datamodel but rather checks of the datatype of fields in the datamodel.

   dump
           Dump Biber::DataModel object

   generate_bltxml_schema
           Generate a RelaxNG XML schema from the datamodel for BibLaTeXML datasources

   generate_bblxml_schema
           Generate a RelaxNG XML schema from the datamodel for bblXML output
