groups

API endpoint base: https://qr1hi.arvadosapi.com/arvados/v1/groups

Object type: j7d0g

Example UUID: zzzzz-j7d0g-0123456789abcde

Resource

Groups provides a way to apply the same permissions to a set of Arvados objects. See permission model for details.

Each Group has, in addition to the Common resource fields:

Attribute Type Description Example
name string
group_class string Type of group. This does not affect behavior, but determines how the group is presented in the user interface. For example, project indicates that the group should be displayed by Workbench and arv-mount as a project for organizing and naming objects. "project"
null
description text
properties hash User-defined metadata, may be used in queries using subproperty filters
writable_by array List of UUID strings identifying Users and other Groups that have write permission for this Group. Only users who are allowed to administer the Group will receive a full list. Other users will receive a partial list that includes the Group’s owner_uuid and (if applicable) their own user UUID.
trash_at datetime If trash_at is non-null and in the past, this group and all objects directly or indirectly owned by the group will be hidden from API calls. May be untrashed.
delete_at datetime If delete_at is non-null and in the past, the group and all objects directly or indirectly owned by the group may be permanently deleted.
is_trashed datetime True if trash_at is in the past, false if not.

Methods

See Common resource methods for more information about create, delete, get, list, and update.

Required arguments are displayed in green.

contents

Retrieve a list of items owned by the group.

Arguments:

Argument Type Description Location Example
uuid string The UUID of the group in question. path
limit integer (default 100) Maximum number of items to return. query
order array Attributes to use as sort keys to determine the order resources are returned, each optionally followed by asc or desc to indicate ascending or descending order. Sort within a resource type by prefixing the attribute with the resource name and a period. query ["collections.modified_at desc"]
filters array Conditions for filtering items. query [["uuid", "is_a", "arvados#job"]]
recursive boolean (default false) Include items owned by subprojects. query true
exclude_home_project boolean (default false) Only return items which are visible to the user but not accessible within the user’s home project. Use this to get a list of items that are shared with the user. query true

Note: Because adding access tokens to manifests can be computationally expensive, the manifest_text field is not included in listed collections. If you need it, request a list of collections with the filter ["owner_uuid", "=", GROUP_UUID], and "manifest_text" listed in the select parameter.

Note: Use filters with the attribute format <item type>.<field name> to filter items of a specific type. For example: ["pipeline_instances.state", "=", "Complete"] to filter pipeline_instances where state is Complete. All other types of items owned by this group will be unimpacted by this filter and will still be included.

create

Create a new Group.

Arguments:

Argument Type Description Location Example
group object query

delete

Put a Group in the trash. This sets the trash_at field to now and delete_at field to now + token TTL. A trashed group is invisible to most API calls unless the include_trash parameter is true. All objects directly or indirectly owned by the Group are considered trashed as well.

Arguments:

Argument Type Description Location Example
uuid string The UUID of the Group in question. path

get

Gets a Group’s metadata by UUID.

Arguments:

Argument Type Description Location Example
uuid string The UUID of the Group in question. path

list

List groups.

See common resource list method.

show

show groups

Arguments:

Argument Type Description Location Example
uuid string path

update

Update attributes of an existing Group.

Arguments:

Argument Type Description Location Example
uuid string The UUID of the Group in question. path
group object query

untrash

Remove a Group from the trash. This sets the trash_at and delete_at fields to null.

Arguments:

Argument Type Description Location Example
uuid string The UUID of the Group to untrash. path
ensure_unique_name boolean (default false) Rename project uniquely if untrashing it would fail with a unique name conflict. query

shared

This endpoint returns the toplevel set of groups to which access is granted through a chain of one or more permission links rather than through direct ownership by the current user account. This is useful for clients which wish to browse the list of projects the user has permission to read which are not part of the “home” project tree.

When called with “include=owner_uuid” this also returns (in the “included” field) the objects that own those projects (users or non-project groups).

Specifically, the logic is:

select groups that are readable by current user AND
    (the owner_uuid is a user (but not the current user) OR
     the owner_uuid is not readable by the current user OR
     the owner_uuid is a group but group_class is not a project)

In addition to the “include” parameter this endpoint also supports the same parameters as the list method.

Argument Type Description Location Example
include string If provided with the value “owner_uuid”, this will return owner objects in the “included” field of the response. query ?include=owner_uuid
