individuals 
data frame with one row for each row in symbolic data table with following columns:
num  symbolic object (described by symbolic data table row) ordering number , usually from 1 to numebr of symbolic objects;
name  short name of symbolic object with no spaces;
label  full descriptive name of symbolic object.

variables 
data frame with one row for each column in symbolic data table with following columns:
num  symbolic variable (adequate to symbolic data table column) ordering number, usually from 1 to number of symbolic variables;
name  short name of symbolic variable with no spaces;
label  full descriptive name of symbolic variable;
type  type of symbolic variable:
IC (InterContinous)  Symbolic interval variable type, every realization of symbolic variable of this type on symbolic object takes form of numerical interval;
C (Continous)  Symbolic interval variable type, every realization of symbolic variable of this type on symbolic object takes form of numerical interval for which begging is equal to end (equivalent to simple "numeric" value);
MN (MultiNominal)  every realization of multi nominal symbolic variable on symbolic objects takes form of set of nominal values;
NM ((Multi) Nominal Modif)  every realization of nominal symbolic variable on symbolic objects takes form of distribution of probabilities (set of nominal values with weights summing to one)
N (Nominal)  every realization of nominal symbolic variable on symbolic objects is one value (or N.A.)
details  id of this variable in details table apropriate for this kind of variable (detailsN for nominal and multi nominal variables, detailsIC for symbolic interval variables,
detailsC for continous (metric singlevalued) variables, detailsNM of multi nominal with weights variables).

detailsC 
data frame describing symbolic continous (metric, singlevalued) variables details with following columns:
na  number of N.A. (not available) variables realization;
nu  not used, left for compatibility with ASSOXML specification;
min  beginning of interval representing symbolic interval variable domain (minimal value of all realizations of this variable on all symbolic objects);
max  end of interval representing symbolic interval variable domain (maximal value of all realizations of this variable on all symbolic objects).

detailsIC 
data frame describing symbolic intercontinous (symbolic interval) variables details with following columns:
na  number of N.A. (not available) variables realizations;
nu  not used, left for compatibility with ASSOXML specification;
min  beginning of interval representing symbolic interval variable domain (minimal value of all beginnings of interval realizations of this variable on all symbolic objects);
max  end of interval representing symbolic interval variable domain (maximal value of all ends of interval realizations of this variable on all symbolic objects).

detailsN 
data frame describing symbolic nominal and multi nominal variables details with following columns:
na  number of N.A. variables realizations;
nu  not used, left for compatibility with ASSOXML specification;
modals  number of categories in symbolic variable domain. Each categorie is described in detailsListNom.

detailsListNom 
data frame describing every category of symbolic nominal and multi nominal variables, with following columns:
details_no  number of variable in detailsN to which domain belongs category;
num  number of category within variable domain;
name  category short name
label  category full name

detailsNM 
data frame describing symbolic multi nominal modiff (categories sets with weights) variables details with following columns:
na number of N.A. (not available) variables realizations.
nu not used, left for compatibility with ASSOXML specification
modals number of categories in symbolic variable domain. Each categorie is described in detailsListNomModiff

detailsListNomModif 
data frame describing every category of symbolic multi nominal modiff variables, with following columns
details_no  number of variable in detailsNM to which domain belongs category
num  number of category within variable domain
name  category short name

indivIC 
array of symbolic interval variables realizations, with dimensions nr_of_objects X nr_of_variables X 2 containing beginnings and ends of intervals for given object and variable. For values different type than symbolic interval array contains zeros

indivC 
array of symbolic continues variables realizations, with dimensions nr_of_objects X nr_of_variables X 1 containing single values  realizations of variable on symbolic object. For values different type than symbolic continous array contains zeros

indivN 
data frame describing symbolic nominal and multi nonimal variables realizations with folowing columns:
indiv  id of symbolic object from individuals;
variable  id of symbolic object from variables;
value  id of category object from detailsListNom;
When this data frame contains line i,j,k it means that category k belongs to set that is realization of jth symbolic variable on ith symbolic object.

indivNM 
data frame describing symbolic multi nonimal modiff variables realizations with folowing columns:
indiv  id of symbolic object from individuals;
variable  id of symbolic object from variables;
value  id of category object from detailsListNom;
frequency  wiught of category;
When this data frame contains line i,j,k,w it means that category k belongs to set that is realization of jth symbolic variable on ith symbolic object with weight(probability) w.
