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).

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.
