Genesys API reference manual

1. Security

Access to selected resources in Genesys is protected and user permissions are checked before any API action is executed. Each organization contributing data to Genesys will have one or more registered user accounts on Genesys.

To modify any data in Genesys, you will need appropriate permissions. Permission to access and manage data for the organization is granted by helpdesk@genesys-pgr.org upon request. Please contact helpdesk@genesys-pgr.org with the list of FAO WIEWS codes of institutes you wish to manage.

To access resources with the APIs described in this manual, you will first need to create a user account. The simplest way is to use your Google+ account, or alternatively to create an account manually.

Figure 1. Creating a user account

Access to the APIs is managed by the OAuth 2.0 protocol and implemented using spring-security OAuth modules. To obtain OAuth access and refresh tokens, you will first need a valid Client ID and Client Secret. These are generated by helpdesk@genesys-pgr.org for each individual consumer application. The ID and Secret listed below are valid for the Sandbox environment and allow out-of-band authentication when using curl in the examples in this manual.

Table 1. Client ID and Secret for out-of-band authentication
Client ID	`dLCiR.MzwkNha18ImEcw0ADli0@sandbox.genesys-pgr.org`
Client Secret	`wGmRAhVplWLEVWlqiMT712PMnaqOa8FN`

1.1. Obtaining the access token

Most OAuth libraries, including the genesys-client-api Java library, will automatically obtain the access token following the OAuth protocol. This section describes how to manually obtain the tokens.

1.1.1. Authorization grant

Log in to Genesys with your account or Google+.

Obtain a verifier code by granting access to the "Genesys API reference" client. This is initiated by opening the authorization URL in a browser (please substitute CLIENTID and SECRET with valid data):

https://sandbox.genesys-pgr.org/oauth/authorize?client_id=CLIENTID&client_secret=SECRET&response_type=code&redirect_uri=oob&scope=write

The server will prompt you to authorize the access to your protected resources on Genesys. After your confirmation, the server will present an authorization code (which will look like: 7wXP1r). From a shell, execute the following curl command, with your authorization code in place of THECODE:

$ curl 'https://sandbox.genesys-pgr.org/oauth/token?grant_type=authorization_code&client_id=CLIENTID&client_secret=SECRET&redirect_uri=oob&code=THECODE'

1.1.2. Username and password

The password grant is available to trusted, secure clients (e.g. desktop applications) where the user’s password will not be captured or stored — i.e. it will be used once. A password grant can be used as follows:

$ curl 'https://sandbox.genesys-pgr.org/oauth/token' --data 'scope=write+read&grant_type=password&username=USERNAME&password=PASSWORD&client_id=CLIENT_ID&client_secret=CLIENT_SECRET'

1.1.3. Client credentials

System-to-system integration should not require user interaction. For that specific purpose, Genesys allows for an OAuth 2.0 client credentials grant.

With Genesys release 2.3, the client authentication grant is also supported. Kindly contact helpdesk@genesys-pgr.org for information on how to enable system-to-system integration and to grant your client the appropriate permissions on Genesys.

The client will be able to modify any data on Genesys on your behalf.

For more details, read the section "Client Credential Grant" in A Guide To OAuth 2.0 Grants.

To obtain a valid (but short-lived) access token, a simple POST request to Genesys is required:

$ curl -X POST 'https://sandbox.genesys-pgr.org/oauth/token?grant_type=client_credentials&client_id=CLIENTID&client_secret=SECRET&redirect_uri=oob'

This type of grant takes out the user authentication and authenticates the remote system with Genesys, immediately issuing an access token.

1.1.4. Successful authorization

The server will respond with access token details in JSON format:

{
        "access_token": "28d96a4e-9a31-479b-abc8-17ee1e8c9906",
        "token_type": "bearer",
        "refresh_token": "2583fd78-bd88-4c2b-afc0-fb231b37d95f",
        "expires_in": 43199,
        "scope": "read write"
}

You can use the access token to sign future HTTP requests to the API by adding a HTTP request header:

Authorization: Bearer OAUTH-ACCESS-TOKEN

as a curl parameter:

curl -H "Authorization: Bearer OAUTH-TOKEN" https://sandbox.genesys-pgr.org

or by including it in the request URL as a query string parameter:

$ curl 'https://sandbox.genesys-pgr.org/api/v0/me?access_token=OAUTH-ACCESS-TOKEN'

1.2. Using the refresh token

OAuth access tokens have a fairly short lifetime. When an access token expires, the refresh token can be used to obtain a new access token. The refresh token is returned as part of the JSON response when a verification code is used to obtain the access token:

{
        "access_token": "28d96a4e-9a31-479b-abc8-17ee1e8c9906",
        "token_type": "bearer",
        "refresh_token": "2583fd78-bd88-4c2b-afc0-fb231b37d95f",
        "expires_in": 43199,
        "scope": "read write"
}

The refresh token must be securely persisted and can be used to request a new access token when the previous access token expires:

$ curl 'https://sandbox.genesys-pgr.org/oauth/token?grant_type=refresh_token&client_id=CLIENTID&client_secret=SECRET&redirect_uri=oob&refresh_token=OAUTH-REFRESH-TOKEN'

2. Client errors

The API returns descriptive information in the response body about why the request failed to execute.

2.1. 401 Unauthorized

401 Unauthorized indicates that the request did not include valid authentication data. Check your OAuth access token.

401 Unauthorized error message

HTTP/1.1 401 Unauthorized
Content-Type: application/json;charset=UTF-8
...
WWW-Authenticate: Bearer realm="genesys2", error="unauthorized", error_description="An Authentication object was not found in the SecurityContext"

{"error":"unauthorized","error_description":"An Authentication object was not found in the SecurityContext"}

3. Managing passport data

Passport data is based on the FAO/Bioversity Multi-crop Passport Descriptors (MCPD V.2) format.

Accession records are upserted, meaning that:

when the matching accession record exists, it will be updated.
when it 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.

3.1. 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). However, genebanks maintaining two or more collections of crops sometimes use identical accession numbers in different collections.

For this reason, Genesys uses the INSTCODE, ACCENUMB and GENUS triplet to uniquely identify an accession. For accessions with a digital object identifier ( DOI) assigned in the ITPGRFA Secretariat Global Information System ( GLIS), it will use the DOI to uniquely identify the record.

        ...
}

1	Holding institute code (INSTCODE)
2	DOI of the accession as registered in GLIS
3	Accession number (ACCENUMB)
4	Genus (GENUS)

3.2. JSON data model

The JSON data model of accession passport data closely follows 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. In such a case the Accession JSON object must always provide three identifying elements: instCode, acceNumb and genus. All other fields are optional.

COLLDATE	Collecting date of the sample, in the format `YYYYMMDD`. Missing data (`MM` or `DD`) may be indicated with two hyphens or two zeros.
COLLSITE	Location information below the country level that describes where the accession was collected, preferably in English. This might include the distance in kilometers and direction from the nearest town, village or map grid reference point (e.g. `7km south of Curitiba in the state of Parana`).
COLLNUMB	Original identifier assigned by the collector(s) of the sample, normally composed of the name or initials of the collector(s) followed by a number (e.g. `FM9909`). This identifier is essential for identifying duplicates held in different collections.
COLLSRC	Collecting/acquisition source.
COLLCODE	FAO WIEWS code of the institute that collected the sample.
COLLNAME	Name of the institute that collected the sample. This descriptor should only be used if COLLCODE cannot be filled because the FAO WIEWS code for this institute is not available.
COLLINSTADDRESS	Address of the institute that collected the sample. This descriptor should only be used if COLLCODE cannot be filled because the FAO WIEWS code for this institute is not available.
COLLMISSID	Identifier of the collecting mission as used by the collecting institute (e.g. `CIATFOR-052`, `CN426`).

3.5. 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.

        "orgCty": null
}

3.6. 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.

Only the instCode and acceNumb are required (and in some cases the genus). The server will return an error when the instCode of JSONs does not match the instCode in the URL!

3.7. 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 the corresponding accession records from Genesys. The DELETE permission is required for this operation.

The delete operation will fail if C&E data exists for any accessions listed.

4. Managing accession images

Institutes can upload accession images to the Genesys repository. Genesys will store and maintain images and metadata provided by institutes and display the images with accession passport data.

Genesys supports image galleries only for institutes that use unique ACCENUMB within their institute.

Managing accession images in Genesys is done through methods available in the /api/v0/img/{instCode}/ namespace.

4.1. Listing existing galleries

To list existing accession image galleries for the INSTCODE, you must have the WRITE or CREATE permission on the institute record. Issue a GET request to the /api/v0/img/{instCode}/_galleries endpoint:

$ curl 'https://sandbox.genesys-pgr.org/api/v0/img/XXX001/_galleries?page=1' -i -X GET \
    -H 'Content-Type: application/json;charset=UTF-8'

5. Managing requests

Institutes can allow users to request material through Genesys. Genesys will validate the user’s email address (by waiting for them to click the confirmation link sent to their address) and also check if the user is registered with ITPGRFA’s Easy-SMTA database.

Genesys maintains a database of requests received, confirmed and dispatched to genebanks holding the requested materials. This API allows genebanks to retrieve the request data from Genesys for automated integration into their existing information systems.

A client may request material from several different genebanks in one session. Genesys splits the request and dispatches sub-requests to email addresses registered with individual genebanks.

Managing crop data in Genesys is done through methods available in the /api/v0/requests namespace.

5.1. Listing requests

To list all requests for a given INSTCODE, you must have the ADMINISTRATOR permission on the institute record. Issue a GET request to the /api/v0/requests/{instCode} endpoint:

6. Managing crop data

Genesys maintains a database of crops and crop groups (e.g. forages). In addition to the general description, each crop defines a list of taxonomic rules that determine which taxonomies are included (or excluded) in the group.

Crops and crop groups are referred to and identified by the crop’s short name. The short name placeholder in documentation below is marked by {shortName}. The short name should have no spaces and it should contain US-ASCII characters only (a-Z, 0-9).

6.1. Crop taxonomic rules

The common crop name of an accession in Genesys is determined by its taxonomy. For example, the crop banana includes accessions of the genus Musa.

Each crop and crop group defines its own taxonomic rules.
The genus, species and sub-species data of an accession is matched against all taxonomic rules.
1. The accession is linked with all matching crops.
2. The accession may have more than one "crop".

Managing crop data in Genesys is done through methods available in the /api/v0/crops namespace.

6.2. Listing all crops

A number of crops and crop groups are usually defined and used in Genesys. To list all crops, issue a GET request to the /api/v0/crops/ endpoint:

$ curl 'https://sandbox.genesys-pgr.org/api/v1/crops' -i -X GET \
    -H 'Content-Type: application/json;charset=UTF-8'

The result is a JSON array of all crops in Genesys.

        "name": "Barley", ...
},
...]

1	Some JSON elements removed for readability.

6.3. Retrieving crop data

The crop details are retrievable with a GET request to /api/v0/crops/{shortName}.

Table 9. `/api/v1/crops/{shortName}`
Parameter	Description
`+shortName+`	Crop short name or code (e.g. maize)

Sample curl request to fetch maize crop definition

$ curl 'https://sandbox.genesys-pgr.org/api/v1/crops/maize' -i -X GET \
    -H 'Content-Type: application/json;charset=UTF-8'

The JSON representation of a single crop record includes the following fields.

Table 10. Fields of crop records
Path	Type	Description
`+id+`	`+Number+`	Autogenerated ID
`+version+`	`+Number+`	Record version
`+name+`	`+String+`	Crop name in English
`+shortName+`	`+String+`	Crop short name or code (e.g. maize)
`+description+`	`+String+`	Crop description in English
`+rdfUri+`	`+String+`	URI of RDF term describing the crop
`+i18n+`	`+String+`	i18n map
`+otherNames+`	`+Array+`	Alternative spellings of the crop name

6.3.1. Taxonomic rules

The /api/v0/crops/{shortName}/rules endpoint exposes access to a crop’s taxonomic rules. We mentioned earlier that accessions with the genus Musa belong to bananas; similarly, accessions of the Zea genus belong to maize:

Maize taxonomic rules

$ curl 'https://sandbox.genesys-pgr.org/api/v1/crops/maize/rules' -i -X GET \
    -H 'Content-Type: application/json;charset=UTF-8'

Result of request for maize taxonomic rules

        "genus": "Zea", (2)
        "species": null, (3)
        "subtaxa": null, (4)
}]

1	The combination of genus, species and subtaxa can be either included or explicitly excluded from the crop.
2	An accession is included in maize when accession’s genus value is `Zea`.
3	Species field is `null` meaning that accession species is ignored by this rule.
4	Subtaxa field is `null` meaning that accession subtaxa value is ignored by this rule.

6.3.2. Exclusion rule

A rule can explicitly exclude accessions matching a particular combination of genus + species + subtaxa. This is useful, for example, in order to include all accessions of the Solanum genus except for selected species (e.g. Solanum melongena).

6.4. Registering a new crop

To create a new crop, a JSON with the following data must be submitted.

Example request to register a new crop

$ curl 'https://sandbox.genesys-pgr.org/api/v1/crops/save' -i -X POST \
    -H 'Content-Type: application/json;charset=UTF-8' \
    -d '{"shortName":"rice","name":"Rice","description":"Crop description in EN"}'

6.5. Localization of crop title and description

The i18n field of the JSON crop object is a string encoded JSON object of a two level JSON formatted dictionary string with first level keys name (for the name field) and description (for the description field) and second level keys corresponding to ISO_639_2 encoded vernacular language tags.

6.6. Updating taxonomic rules

Taxonomic rules can be replaced using one call by providing the new list of rules as the body of the HTTP PUT call to /api/v0/crops/{shortName}/rules. To specify that all Triticum and Aegilops species should be included in wheat, you would send the following array of rules to /api/v0/crops/wheat/rules

Rule array to include multiple species in a crop

Setting new taxonomic rules for the selected crop

$ curl 'https://sandbox.genesys-pgr.org/api/v0/crops/maize/rules' -i -X PUT \
    -H 'Content-Type: application/json;charset=UTF-8' \
    -d '[{"id":-20498,"included":true,"genus":"Zea","species":"mays","subtaxa":"var. foobaria","_class":"CropRule"}]'

Table 12. Taxonomic rule fields
Path	Type	Description
`+[].included+`	`+Boolean+`	Specifies whether the rule is an including or an excluding rule
`+[].genus+`	`+String+`	Accession is included in the crop when its genus matches specified value.
`+[].species+`	`+String+`	Accession is included in the crop when its species matches specified value.
`+[].subtaxa+`	`+String+`	Accession is included in the crop when its subtaxa matches specified value.

6.7. Deleting a crop

A crop record can be deleted by issuing an HTTP DELETE request to /api/v0/crops/{shortName}. This will remove the crop and crop rules from the system.

Deleting a crop

$ curl 'https://sandbox.genesys-pgr.org/api/v1/crops/rice' -i -X DELETE \
    -H 'Content-Type: application/json;charset=UTF-8'
