API endpoint base: @https://{{ site.arvados_api_host }}/arvados/v1/groups@

Object type: @j7d0g@

Example UUID: @zzzzz-j7d0g-0123456789abcde@

h2. Resource

Groups provides a way to apply the same permissions to a set of Arvados objects.  See "permission model":{{site.baseurl}}/api/permission-model.html for details.

Each Group has, in addition to the "Common resource fields":{{site.baseurl}}/api/resources.html:

table(table table-bordered table-condensed).
|_. 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":{{site.baseurl}}/api/methods.html#subpropertyfilters ||
|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.||

h2. Methods

See "Common resource methods":{{site.baseurl}}/api/methods.html for more information about @create@, @delete@, @get@, @list@, and @update@.

Required arguments are displayed in %{background:#ccffcc}green%.

h3. contents

Retrieve a list of items owned by the group.

Arguments:

table(table table-bordered table-condensed).
|_. Argument |_. Type |_. Description |_. Location |_. Example |
{background:#ccffcc}.|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@|

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":{{site.baseurl}}/api/methods/collections.html 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.
