22 Collections describe sets of files in terms of data blocks stored in Keep. See "storage in Keep":{{site.baseurl}}/api/storage.html for details.
24 Each collection has, in addition to the "Common resource fields":{{site.baseurl}}/api/resources.html:
26 table(table table-bordered table-condensed).
27 |_. Attribute|_. Type|_. Description|_. Example|
30 |portable_data_hash|string|The MD5 sum of the manifest text stripped of block hints other than the size hint.||
31 |manifest_text|text|||
32 |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@|
33 |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|
34 |replication_confirmed_at|datetime|When replication_confirmed was confirmed. If replication_confirmed is null, this field is also null.||
36 h3. Conditions of creating a Collection
38 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@.
40 h3. Side effects of creating a Collection
42 Referenced blocks are protected from garbage collection in Keep.
44 Data can be shared with other users via the Arvados permission model.
48 See "Common resource methods":{{site.baseurl}}/api/methods.html for more information about @create@, @delete@, @get@, @list@, and @update@.
50 Required arguments are displayed in %{background:#ccffcc}green%.
54 Create a new Collection.

64 Delete an existing Collection.
68 table(table table-bordered table-condensed).
69 |_. Argument |_. Type |_. Description |_. Location |_. Example |
70 {background:#ccffcc}.|uuid|string|The UUID of the Collection in question.|path||
74 Gets a Collection's metadata by UUID.

86 See "common resource list method.":{{site.baseurl}}/api/methods.html#index
88 Note: Because adding access tokens to manifests can be computationally expensive, the @manifest_text@ field is not included in results by default. If you need it, pass a @select@ parameter that includes @manifest_text@.
92 Update attributes of an existing Collection.
