function specifications = fao_total_specifications_2023(sourcename)
% fao_specifications just creates a structure containing all informations
%   needed to parse the fao files...
%
% INPUT PARAMETERS: None
%
% RETURN PARAMETERS:
%   specifications: a structure with many constants needed to parse the
%   input xls files for the program read_bulkplus_sheet.
%   specifications contains two fields, 'keystruct', and 'mapstruct'.
%   - specifications.keystruct - is a structure of sheet fieldnames (e.g.
%     'sheet_category'), where the value is a cellstr of the labels that
%     should be used to assign the value. The list is taken in the order it
%     is listed.
%   - specifications.mapstruct - is a structure that maps column headers (or other
%     inputs, such as $filename or $sheetname for the filename or sheetname,
%     respectively) to the values to be assigned to sheet fields.
%     mapstruct.names contains the list of headers names, where the index of
%     each header corresponds to the field 'var[index]'. mapstruct.varX
%     contains the field 'value', as well as fields for each sheet
%     fieldname (e.g. sheet_category) that gets mappings from this
%     parameter source. the field 'value' can have three types of values:
%     - a cellstr of possible values in the input file. In this case,
%     cellstrs of the same length are given for the sheet fieldnames, which
%     provide the values to map too.
%     - the string 'echo'. In this case, the value in the input file is fed
%     to a function, the name of which is given in the sheet fieldname
%     fields. if the function is an empty string, then the value in the
%     input file is simply fed directly.
%     - the string 'split'. In this case, the value in the input file for
%     this column is a year, such that before this year the data is to have
%     one designation, and after and including this year, it is to have a
%     different designation. (this is used for the IMF WEO data). The
%     designations are provided in the sheet fieldname field.
%
%
% GLOBALS:
% CONSTANTS: A structure containing string and numeric constants, which are
%           used in the PRIMAP functions. These are configurations like
%           scaling factors, but also fieldnames for the database and
%           mapping vectors etc.

% we need an new FAO specification because the new emission data does not really fit into the old categories
% we now have the following
% * Emissions on agricultural land
% = Farm-gate emissions + Fires in humid tropical forests + Net Forest conversion + Fires in organic soils
% * Farm-gate emissions (1)
% = Enteric Fermentation (1A) + Manure Management (1B) + Rice Cultivation (1C) + Synthetic Fertilizers (1D)
% + Manure applied to Soils (1E) + Manure left on Pasture (1F) + Crop Residues (1G) + Burning - Crop residues (1J)
% + Drained organic soils (1H, CO2 and N2O) + On-farm energy use (1K)
% * FORESTLAND = Forestland + Forest fires
% * LAND USE CHANGE = Fires in humid tropical forests + Net Forest conversion + Fires in organic soils
% (FORESTLAND and LAND USE CHANGE are not available in the csv files, but named on the
% "FAOSTAT Domain Emissions Totals. Metadata" document)


% IPCC type categories
% AFOLU = IPCC Agriculture + LULUCF
% IPCC Agriculture = Farm-gate emissions - On-farm energy use - Drained organic soils (CO2)

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% MAPPING %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% LISTS MAPPING BETWEEN VALUES IN THE INPUT FILE AND VALUES FOR THE
% DATATABLES. THE COLUMN HEADERS (OR $filename or $sheetname FOR THE
% FILENAME OR EXCEL SHEETNAME, RESPECTIVELY) ARE LISTED IN FIELD name.
% STANDARD INPUT FOR var[i].value IS TO PROVIDE A CELLSTR OF ALL VALUES
% FROM THE COLUMN LISTED IN name{i} THAT ARE TO BE ASSIGNED. VALUES TO BE
% IGNORED CAN BE LISTED IN FIELD var[i].valuesToIgnore, TO REDUCE WARNING
% MESSAGES. THE SHEET KEYS TO MAP TO ARE LISTED AS FIELDS UNDER var[i],
% WITH THE VALUE IN THE STANDARD CASE BEING A CELLSTR WITH THE SAME LENGTH
% AS THE FIELD value, THAT PROVIDES THE VALUES TO BE USED IN THE
% DATATABLES.
% ALTERNATE INPUTS FOR FIELD value ARE THE STRINGS 'echo' OR
% 'split'. 'echo' PASSES THE INPUT VALUE TO THE FUNCTION LISTED UNDER THE
% SHEET KEY FIELD, AND ASSIGNS THE OUTPUT TO THE SHEET KEY. 'split' ASSUMES
% THAT THE INPUT VALUES IS A YEAR. THE DATA WILL BE SPLIT INTO TWO
% DATATABLES AT THAT YEAR, WITH THAT YEAR BEING A PART OF THE SECOND
% DATATABLE. THE FIRST TABLE WILL GET THE FIRST ELEMENT ASSIGNED TO SHEET
% KEY FIELD, AND THE SECOND TABLE WILL GET THE SECOND ELEMENT.
