This schema, among other things, describes the fields in the resource (including the schema URI of related resource fields) and the fields that allow filtering. Valid filtering values are: Django ORM filters (e.g. startswith, exact, lte, etc.) or 1 or 2. If a filtering field is set to 2 it can be filtered over the related resource fields. For example, the locations could be filtered by their pipeline UUID setting it in a request parameter formatted with two underscore chars: <code>/api/v2/location/?pipeline__uuid=<uuid></code>

Main Page > Development > Storage Service API

This page is no longer being maintained and may contain inaccurate information. Please see the Archivematica documentation for up-to-date information.

The Storage Service API provides programmatic access to moving files around in storage areas that the Storage Service has access to.

The API is written using TastyPie.

Improvement Note: TastyPie is less well supported than Django REST Framework, both in terms of docs & community. We should look at replacing TastyPie with DRF.

Endpoints require authentication with a username and API key. This can be submitted as GET parameters (eg ?username=test&api_key=e6282adabed84e39ffe451f8bf6ff1a67c1fc9f2) or as a header (eg Authorization: ApiKey test:e6282adabed84e39ffe451f8bf6ff1a67c1fc9f2)

A note about browsing[edit]

A detailed schema can be found for each of the resources by adding "schema" to the get all URL.

Example: 

$ curl -X GET -H"Authorization: ApiKey test:95141fc645ed97a95893f1f865d24687f89a27ad" 'http://localhost:8000/api/v2/location/schema/?format=json

This schema, among other things, describes the fields in the resource (including the schema URI of related resource fields) and the fields that allow filtering. Valid filtering values are: Django ORM filters (e.g. startswith, exact, lte, etc.) or 1 or 2. If a filtering field is set to 2 it can be filtered over the related resource fields. For example, the locations could be filtered by their pipeline UUID setting it in a request parameter formatted with two underscore chars: /api/v2/location/?pipeline__uuid=<uuid>

Package[edit]

Get all packages[edit]

  • URL: /api/v2/file/
  • Verb: GET

Create new package[edit]

  • URL: /api/v2/file/
  • Verb: POST
  • Parameters: JSON. Fields for a new package:
    • uuid: UUID of the new package
    • origin_location: URI of the Location where the package is currently
    • origin_path: Path to the package, relative to the origin_location
    • current_location: URI of the Location where the package should be stored
    • current_path: Path where the package should be stored, relative to the current_location
    • package_type: Type of package this is. One of: AIP, AIC, DIP, transfer, SIP, file, deposit
    • size: Size of the package
    • origin_pipeline: URI of the pipeline the package is from
    • related_package_uuid: UUID of a package that is related to this one. E.g. UUID of a DIP when storing an AIP

Creates a database entry tracking the package (AIP, transfer, etc). If the package is an AIP, DIP or AIC and the current_location is an AIP or DIP storage location it also moves the files from the source to destination location. If the package is a Transfer and the current_location is transfer backlog, it is also moved.

This is handled through the modified obj_create function, which calls Package.store_aip or Package.backlog_transfer

Get package details[edit]

  • URL: /api/v2/file/<UUID>/
  • Verb: GET

Update package contents[edit]

  • URL: /api/v2/file/<UUID>/
  • Verb: PUT
  • Parameters: JSON body
    • reingest: Flag to mark that this is reingest. Reduces chance to accidentally modify an AIP.
    • uuid: UUID of the existing package
    • origin_location: URI of the Location where the package is currently
    • origin_path: Path to the package, relative to the origin_location
    • current_location: URI of the Location where the package should be stored
    • current_path: Path where the package should be stored, relative to the current_location
    • package_type: Type of package this is. One of: AIP, AIC
    • size: Size of the package
    • origin_pipeline: URI of the pipeline the package is from. This must be the same pipeline reingest was started on (tracked through Package.misc_attributes.reingest_pipeline)

Updates the contents of a package during reingest. If the package is an AIP or AIC, currently stored in an AIP storage location, and the 'reingest' parameter is set, it will call Package.finish_reingest and merge the new AIP with the existing one.

This is implemented using a modified obj_update which calls obj_update_hook.

Update package metadata[edit]

  • URL: /api/v2/file/<UUID>/
  • Verb: PATCH
  • Parameters: JSON body
    • reingest: Pipeline UUID or None.

Used to update metadata stored in the database for the package. Currently, this is used to update the reingest status.

Improvement Note: Currently, this always sets Package.misc_attributes.reingest to None, regardless of what value was actually passed in.

This is implemented using a modified obj_update which calls obj_update_hook. update_in_place also helps.

Delete package request[edit]

  • URL: /api/v2/file/<UUID>/delete_aip/
  • Verb: POST
  • Parameters: JSON body
    • event_reason: Reason for deleting the AIP
    • pipeline: UUID of the pipeline the delete request is from
    • user_id: User ID requesting the deletion. This is the ID of the user on the pipeline, and must be an integer greater than 0.
    • user_email: Email of the user requesting the deletion.

Recover AIP request[edit]

  • URL: /api/v2/file/<UUID>/recover_aip/
  • Verb: POST
  • Parameters: JSON body
    • event_reason: Reason for recovering the AIP
    • pipeline: URI of the pipeline the recovery request is from
    • user_id: User ID requesting the recovery. This is the ID of the user on the pipeline, and must be an integer greater than 0.
    • user_email: Email of the user requesting the recovery.

Download single file[edit]

  • URL: /api/v2/file/<UUID>/extract_file/
  • Verb: GET, HEAD
  • Parameters: Query string parameters
    • relative_path_to_file: Path to the file to download, relative to the location where is stored down to the lowest level.
      E.g.: test01-36d4efb7-83ba-46bf-a171-8c7b965d9dcb/data/objects/MARBLES.TGA, where test01-36d4efb7-83ba-46bf-a171-8c7b965d9dcb contains both the UUID of the package and the name of the transfer which you can find using Get package details (see current_path attribute).
  • Response: Stream of the requested file

Returns a single file from the Package. If the package is compressed, it downloads the whole AIP and extracts it.

This responds to HEAD because AtoM uses HEAD to check for the existence of a file.

Improvement Note: HEAD and GET should not perform the same functions. HEAD should be updated to not return the file, and to only check for existence. Currently, the storage service has no way to check if a file exists except by downloading and extracting this AIP

If the package is in Arkivum, the package may not actually be available. This endpoint checks if the package is locally available. If it is, it is returned as normal. If not, it returns 202 and emails the administrator about the attempted access.

Download package[edit]

  • URL: /api/v2/file/<UUID>/download/
  • URL: /api/v2/file/<UUID>/download/<chunk number>/ (for LOCKSS harvesting)
  • Verb: GET, HEAD
  • Parameters: None
  • Response: Stream of the package

Returns the entire package as a single file. If the AIP is uncompressed, create one file by using `tar`.

If the download URL has a chunk number, it will attempt to serve the LOCKSS chunk specified for that package. If the package is not in LOCKSS, it will return the the whole package.

This responds to HEAD because AtoM uses HEAD to check for the existence of a file.

Improvement Note: HEAD and GET should not perform the same functions. HEAD should be updated to not return the file, and to only check for existence.

If the package is in Arkivum, the package may not actually be available. This endpoint checks if the package is locally available. If it is, it is returned as normal. If not, it returns 202 and emails the administrator about the attempted access.

Get pointer file[edit]

  • URL: /api/v2/file/<UUID>/pointer_file/
  • Verb: GET
  • Parameters: None
  • Response: Stream of the pointer file.

Check fixity[edit]

  • URL: /api/v2/file/<UUID>/check_fixity/
  • Verb: GET
  • Parameters: Query string parameters
    • force_local: If true, download and run fixity on the AIP locally, instead of using the Space-provided fixity if available.
  • Response: JSON
    • success: True if the verification succeeded, False if the verification failed, None if the scan could not start
    • message: Human-readable string explaining the report; it will be empty for successful scans.
    • failures: List of 0 or more errors
    • timestamp: ISO-formated string with the datetime of the last fixity check. If the check was performed by an external system, this will be provided by that system. If not provided,or on error, it will be None.

AIP storage callback request[edit]

  • URL: /api/v2/file/<UUID>/send_callback/post_store/
  • Verb: GET

Request to call any Callbacks configured to run post-storage for this AIP.

In SS0.15 and above, this endpoint has been extended to support callbacks for AIP, AIC and DIP stored events.



Improvement Note: This only works on locally available AIPs (AIPs stored in Spaces that are available via a UNIX filesystem layer).
