Permissions api

This API can be used to perform create, retrieval, update and delete operations on the MOLGENIS permission system. The MOLGENIS permission is based on Spring Security.

Parameters

These parameters are used by the endpoint in this API:

  • 'typeId': This is the type of resource for which the permission is granted.

    This maps to the 'type' in Spring security's ObjectIdentity.

    In MOLGENIS examples of these types are 'entityType', 'package', 'plugin', and also row level secured entities, in which case the type is the entityType identifier prefixed with "entity-"

  • 'identifier': This is the identifier of the actual resource within the resource type for which the permission is granted.

    This maps to the 'identifier' in Spring security's ObjectIdentity.

  • 'inheritance': a boolean indicating if inherited permissions should be returned or only the permission that are actually set for the roles and users requested. This parameter is only used in the GET permission requests. Setting this to true will return a tree with all inherited permissions for the requested users and roles. This field cannot be combined with paging.

  • 'page': The pagenumber for the results, should only be provided combined with 'pageSize'. This field cannot be combined with 'inheritance=true'.

  • 'pageSize': The number of results per result page, should only be provided combined with 'page'. This field cannot be combined with 'inheritance=true'.

  • 'permission': A permission for a resource, the permissions that can be used differ per resource type, but are always a subset of READMETA,COUNT,READ,WRITE,WRITEMETA.

Query for user or role

  • user

    The user for which to get/create/update the permission. This should be the username as stated in the 'sys_sec_User' table in the MOLGENIS database.

  • role

    The role for which to get/create/update the permission. This should be the rolename as stated in the 'sys_sec_Role' table in the MOLGENIS database.

The user/role query for this API's GET operations should be provided in the RSQL syntax Examples:

Query for user 'Cardiologist' or users with role "CARDIOLOGY"

q=user==Cardiologist,role==CARDIOLOGY

Query for users 'Cardiologist' or 'Neurologist'

q=user=in=(Cardiologist,Neurologist)

Permission inheritance

There are two kinds of inheritance in the permission system:

  • Users inherit permissions from their roles, and roles from their parentroles.

  • The access control list (ACL) for a resource can have a parent, in that case permissions on the parent also grant permissions on the child ACL's. In the current MOLGENIS system this is the case for entity types and packages, both inherit permissions from the package in which they reside..
