README

This is an abstraction on top of the PREG (Pre REGistration) API.

Getting started

To use this library, you need to have an application registered on Application Portal. If you do not know what this means, refer to the CERN Authorization Service documentation. Make sure the registered application has OIDC SSO registration. The application needs to be added to the ‘grappa‘ group fence-api-read_{experiment} where experiment is alice, atlas, cms or lhcb.

With your application registered, you will use the Client ID and Client secret.

The official PREG API documentation can be found on the following URLs:

• UI (TEST): https://testhrapi.cern.ch/hrapi/swagger-ui/index.html
• YAML downloadable as a file(TEST): https://testhrapi.cern.ch/hrapi/v3/api-docs.yaml
• JSON exposed as an endpoint(TEST): https://testhrapi.cern.ch/hrapi/v3/api-docs

Usage

The PREG provider is created with application credentials.

// Example of $inProduction. Adapt for your needs!

$preRegistrationProvider = PreRegistrationProvider::createWithAppCredentials(
    $clientId       = getenv("CLIENT_ID"),
    $clientName     = getenv("CLIENT_SECRET"),
    $experimentName = "lhcb",
    $inProduction   = getenv("ENVIRONMENT") === "PRODUCTION",
);

PreRegistrationProvider::getPreRegistrations()

Get experiment's pre registrations.

$registrations = $preRegistrationProvider->getPreRegistrations();

echo($registrations[0]->personId());
echo($registrations[0]->documentId());

// Output:
// 123456
// 1234567

Schemas

The pre registration schema and its available options are as follows:

personId                    => int
documentId                  => int
participationExperiment     => string (example: LHCb)
personNatureOfEmployment    => string ([ ADMINISTRATION, ENGINEERING, PHYSICS, SUMMERSTUDENT, TECHNICAL, OTHER ])
personEducationLevel        => string ([ BSCUNDERGRADUATE, MSCDIPLOMA, OTHER, PHD ])
personStudyingStatus        => string ([ CONCLUDED, STUDYING ])
personSeniorStatus          => ?string ([ SENIOR, NOTSENIOR, NULL]) ## this is an optional field, meaning that NULL does not indicate if the person is a senior or not.
