NAME

       Biber::DataModel - Biber::DataModel objects

   new
           Initialize a Biber::DataModel object

   is_field
           Returns boolean to say if a field is a legal field
           Allows intermediate temp custom fields which are used
           when a driver source field doesn't have an obvious 1:1 mapping
           to a datamodel field. Such intermediates are defined in the target
           field mapping of a sourcemap.

           Also allows for fields with script form and optional lang suffix

   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.

   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 and datatype 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_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

   dump
           Dump Biber::DataModel object
