FAO/IPGRI MULTI-CROP PASSPORT DESCRIPTORS

December 2001

The list of multi-crop passport descriptors  (MCPD), is developed jointly by IPGRI and FAO to provide international standards to facilitate germplasm passport information exchange. These descriptors aim to be compatible with IPGRI crop descriptor lists and with the descriptors used for the FAO World Information and Early Warning System (WIEWS) on plant genetic resources (PGR). 

          For each multi-crop passport descriptor, a brief explanation of content, coding scheme and suggested fieldname (in parentheses) is provided to assist in the computerized exchange of this type of data. It is recognized that networks or groups of users may want to further expand this MCPD List to meet their specific needs.  As long as these additions allow for an easy conversion to the format proposed in the multi-crop passport descriptors, basic passport data can be exchanged worldwide in a consistent manner.

General comments:

·       If a field allows multiple values, these values should be separated by a semicolon (;) without space(s), (i.e. Accession name:Rheinische Vorgebirgstrauben;Emma;Avlon).

·       A field for which no value is available should be left empty (i.e. Elevation). If data is exchanged in ASCII format for a field with a missing numeric value, it should be left empty. If data is exchanged in a database format, missing numeric values should be represented by generic NULL values.

·       Dates are recorded as YYYYMMDD.  If the month and/or day are missing this should be indicated with hyphens. Leading zeros are required. (i.e. 197506--, or 1975----)

·       Latitude and longitude are recorded in an alphanumeric format. If the minutes or seconds are missing, this should be indicated with hyphens. Leading zeros are required.

·       Country names: Three letter ISO codes are used for countries. The ISO 3166-1: Code List can be found at: http://www.un.org/Depts/unsd/methods/m49alpha.htm. Country or area numerical codes added or changed are not available on line, but can be obtained from IPGRI [t.metz@cgiar.org]. 

·       For institutes the codes from FAO should be used. These codes are available from http://apps3.fao.org/wiews/ for registered WIEWS users. From the Main Menu select: “PGR” and “Download”.  If new Institute Codes are required, they can be generated online by national WIEWS administrators, or by the FAO WIEWS administrator [Stefano.Diulgheroff@fao.org].

·       Preferred language for free text fields is English (i.e. Location of collecting site and Remarks).

 

MULTI-CROP PASSPORT DESCRIPTORS

1. Institute code                                                                                                  (INSTCODE)

1    To convert from longitude and latitude in degrees (º), minutes ('), seconds (''), and a hemisphere (North or
 
South and East or West) to decimal  degrees, the following formula should be used:

dº m' s'' = h * (d + m / 60 + s / 3600)

              where h = 1 for the Northern and Easter hemisphere and -1 for the Southern and Western hemisphere. I.e.,

        30º30'0'' S = -30.5 and 30º15'55'' N =  30.265.
