-h2. create
+h2. Resource
-Create a new Collection.
+Collections describe sets of files in terms of data blocks stored in Keep. See "storage in Keep":{{site.baseurl}}/api/storage.html for details.
-Arguments:
+Each collection has, in addition to the "Common resource fields":{{site.baseurl}}/api/resources.html:
table(table table-bordered table-condensed).
-|_. Argument |_. Type |_. Description |_. Location |_. Example |
-|collection|object||query||
+|_. Attribute|_. Type|_. Description|_. Example|
+|name|string|||
+|description|text|||
+|properties|hash|User-defined metadata, may be used in queries using "subproperty filters":{{site.baseurl}}/api/methods.html#subpropertyfilters ||
+|portable_data_hash|string|The MD5 sum of the manifest text stripped of block hints other than the size hint.||
+|manifest_text|text|||
+|replication_desired|number|Minimum storage replication level desired for each data block referenced by this collection. A value of @null@ signifies that the site default replication level (typically 2) is desired.|@2@|
+|replication_confirmed|number|Replication level most recently confirmed by the storage system. This field is null when a collection is first created, and is reset to null when the manifest_text changes in a way that introduces a new data block. An integer value indicates the replication level of the _least replicated_ data block in the collection.|@2@, null|
+|replication_confirmed_at|datetime|When replication_confirmed was confirmed. If replication_confirmed is null, this field is also null.||
+|trash_at|datetime|If @trash_at@ is non-null and in the past, this collection will be hidden from API calls. May be untrashed.||
+|delete_at|datetime|If @delete_at@ is non-null and in the past, the collection may be permanently deleted.||
+|is_trashed|datetime|True if @trash_at@ is in the past, false if not.||
-h2. delete
+h3. Conditions of creating a Collection
-Delete an existing Collection.
+The @portable_data_hash@ and @manifest_text@ attributes must be provided when creating a Collection. The cryptographic digest of the supplied @manifest_text@ must match the supplied @portable_data_hash@.
-Arguments:

+Referenced blocks are protected from garbage collection in Keep.

-h2. get
+h3. delete
-Gets a Collection's metadata by UUID.
+Put a Collection 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.
Arguments:
|_. Argument |_. Type |_. Description |_. Location |_. Example |
{background:#ccffcc}.|uuid|string|The UUID of the Collection in question.|path||
-h2. index
+h3. get

Arguments:
table(table table-bordered table-condensed).
|_. Argument |_. Type |_. Description |_. Location |_. Example |
-|order|string||query||

-|order|string|Order in which to return matching collections.|query||
-|pageToken|string|Page token.|query||
-|q|string|Query string for searching collections.|query||
