documentation and formats for data exchange. It documents Genesys extensions to
the standards.[Genesys PGR] (Plant Genetic Resources) is a free online global portal accessible at
that allows the exploration of the world’s crop diversity through a single website. The
data published on Genesys follows the <<mcpd,Multi-crop Passport Descriptors>> standard.

== Accession documentation in genebanks
Collections of PGRFA material in genebanks document at least the following for each accession
* <<accedoc-accenumb,Accession number>>
* Acquisition date `ACQDATE` when accession entered the collection
* <<accedoc-other,Other accession identifiers>>
* <<accedoc-tax,Taxonomy>>
* <<accedoc-storage,Storage and maintenance>>
A single accession is usually maintained as several individual *inventories* or lots, where each inventory
follows different management policies and is maintained in different conditions (e.g. cryo and in vitro,
or base and active collection).
Inventory management is a topic of genebank collection management and is not further described here.
=== Accession number
Accession number is the unique identifier assigned to the material as it enters
the collection. This identifier generally has three components:
Prefix + Sequence number + Suffix
The *prefix* is commonly used to differentiate between different crop collections
maintained by the genebank.
.Some prefixes used by[IITA] genebank
* `TMe` Cassava _Manihot esculenta_ collection
* `TVSu` Bambara groundnut _Vigna subterranea_ collection
* `TZm` Maize _Zea mays_ collection
*Sequence number* is assigned manually or by a computer system to ensure there are
no duplicates. Some institutes prefer to zero-pad the number `00000102`.
The *suffix* allows differentiating samples of the same original material. The
exact meaning of the suffix is different for every institute.

.Example accession numbers
|Prefix|Sequence number|Suffix|Accession number
=== Other accession identifiers
Material enters the collection by collecting, from breeding programs,
or acquisition from other institutes. In each case, the material will already have some
identifier assigned by the collector, breeder or other institute.
*Accession name* is the vernacular name of the material and is commonly captured by
the collector or assigned by the breeder.
==== Collected material
Genebank accessions obtained through collecting missions should maintain data about the site and dates of the
collecting and collector information.
==== Breeders material
Lines developed by breeding programs of the institute may be included the collection. Information provided by the breeders
should include the pedigree, ancestral information of the material, along with names and identifiers used by the breeding
program and the codes and names of institutes that developed the material.
==== Acquisitions
Material coming from other institutes and genebanks must be accompanied by accession passport data
as documented in the source genebank.
NOTE: *Country of origin* is the country where the material was collected or bred, not the country of source genebank.
Accession documentation should capture any identifiers provided by the source institute. This data
allows for validation and curation of passport data between the genebanks and allows researchers
to obtain material from either collection.
=== Taxonomy
Accession genus, species, species author, subtaxon and subtaxon authority are usually
known, but are subject to change after expert identification or change in taxonomic system.[GRIN Taxonomy for Plants] and the Mansfeld database can serve for validating accession taxa.
=== Storage and maintenance
Ex situ genebanks maintain PGR material as seed, in the field, in vitro, cryo or in DNA collections.
Inventories (lots) of one accession may be managed by different methods (e.g. seed and cryo).
See <<mcpd-storage,Storage>> in MCPD standard on how to capture multiple types of storage.
== Managing Passport Data
Passport data is based on FAO Multi-Crop Passport Descriptors <<mcpd2>> format.
Accession records are *upserted*, meaning that when the matching accession record
. exists, it will be updated
. does not exist, a new record will be created
Accession data in the database will be updated with whatever data is provided in the
request JSON.
=== Accession identity
Prior to full adoption of Permanent Unique Identifiers for Germplasm, accessions could be
identified by the holding institute code (INSTCODE) and the accession number (ACCENUMB).
Genebanks maintaining two or more collections of crops would sometimes use the same
accession number, unique within one collection.
Genesys uses the *instCode*, *acceNumb* and *genus* triplet to uniquely identify an
accession in an institute:
"instCode": "NGA039", <1>
"acceNumb": "TMp-123", <2>
"genus": "Musa" <3>
<1> Holding institute code (INSTCODE)
<2> Accession number (ACCENUMB)
<3> Genus (GENUS)
=== JSON data model
The JSON data model of accession passport data closely follows <<mcpd2, MCPD>> definitions.
By default, institutes in Genesys are configured to "Use unique accession numbers within the institute".
The accession JSON object must provide two identifying elements: `instCode` and `acceNumb`.
In cases where accession numbers are not unique within the institute, `genus` is used to identify
the unique accession within the institute. Then the Accession JSON object must always provide three
identifying elements: `instCode`, `acceNumb` and `genus`.
All other fields are optional.

"acceNumb": "M12345",

"species": "acuminata",

"acceUrl": "",
"geo": {
... <1>
"coll": {
... <2>
<1> JSON object with geographic data
<2> JSON object with collecting data
=== Clearing existing values
To reset or clear an existing value in the accession passport data, it should be provided
as `null`. Not providing a field means the field in the database should not be modified.
"instCode": "NGA039",
"acceNumb": "TMp-123",
"genus": "Musa",
"orgCty": null <1>
<1> Country of origin of accession is cleared by sending a `null` value.
=== Insert or update accessions
REST endpoint URL `/api/v0/acn/{instCode}/upsert` allows for inserting new accessions
or updating existing records in Genesys. It accepts a JSON array of Accession JSON objects.
The array provides for sending batches of 50 or 100 accessions in one call, reducing
the HTTP overhead and improving performance.
NOTE: Only the instCode and acceNumb are required (And in some cases genus).
NOTE: If a property is set to `null`, the existing value will be removed from the database.
NOTE: The server will return an error when `instCode` of JSONs does not match the `instCode` in the URL!
=== Deleting accessions
With the introduction of permanent identifiers for accession records in Genesys we have
also introduced the *Accession Archive*. The Archive holds passport data for accession records
that have been deleted from the active database.
REST endpoint URL `/api/v0/acn/{instCode}/delete` accepts an array of `instCode`, `acceNumb`, `genus` triplets
and deletes corresponding accession record from Genesys. The *DELETE* permission is required for this operation.
NOTE: Delete operation will fail if C&E data exists for any accessions listed.

The[World Information and Early Warning System (WIEWS)]
on Plant Genetic Resources for Food and Agriculture (PGRFA), has been established by FAO,
as a world-wide dynamic mechanism to foster information exchange among Member Countries and as an instrument for the periodic
assessment of the State of the World's PGRFA.
The FAO WIEWS database contains basic information about institutes working with PGRFA. The data includes
full names, acronyms, website links and contact information.
Genesys regularly updates the list of institutes from the FAO WIEWS database and makes them accessible
NOTE: This data cannot be directly managed through Genesys, changes must be applied to the WIEWS database.
=== WIEWS Institute Codes
The FAO WIEWS code of the institute consist of the 3-letter <<iso-3166,ISO 3166-1 alpha 3>> country code of
the country where the institute is located plus a number (e.g. COL001, USA1004).
The Multi-Crop Passport Descriptors standard relies on WIEWS codes.
The automated import of institute data allows Genesys to present individual pages for
genebanks registered in FAO WIEWS database.
