Loading specification (draft)
=============================
Loading specification
=====================
This part discusses the deposit loading part on the server side.
AN important part of the deposit specifications is the loading procedure whereas
a deposit is ingested into the Software Heritage (archive), using
the tarball loader and the complete schema of software artifacts creation
in the archive.
Tarball Loading
---------------
......@@ -14,26 +17,316 @@ The loading of the deposit will use the deposit's associated data:
* the metadata
* the archive(s)
We will use the ``synthetic`` revision notion.
To that revision will be associated the metadata. Those will be included
in the hash computation, thus resulting in a unique identifier.

Origin artifact
~~~~~~~~~~~~~~~~
We create an origin using the url in the deposited metadata.
The current deposit and future deposits with the same url or external_id
will be associated to this origin.
.. code-block:: json
origin: {
"id": 89283768,
"origin_visits_url": "/api/1/origin/89283768/visits/",
"type": "deposit",
"url": "https://hal.archives-ouvertes.fr/hal-02140606"
}
Visits
~~~~~~~
We identify with a visit each deposit push of the same external_id.
Here in the example below, two snapshots are identified by two different visits.
.. code-block:: json
visits: [
{
"date": "2019-06-03T09:28:10.223007+00:00",

}
]
Snapshot artifact
~~~~~~~~~~~~~~~~
The snapshot represents one deposit push. The master branch points to a
synthetic revision. We will create a second branch pointing to a release
artifact, if the indicate that the deposit is a release with a `releaseNotes`.
.. code-block:: json
snapshot: {
"branches": {
"master": {
"target": "396b1ff29f7c75a0a3cc36f30e24ff7bae70bb52",

}
},
"id": "a3773941561cc557853898773a19c07cfe2efc5a",
"next_branch": null
}
Release artifact
~~~~~~~~~~~~~~~~
The content is deposited with a set of descriptive metadata in the CodeMeta
vocabulary. The following CodeMeta terms implies that the
artifact is a release:
- `releaseNotes`
- `softwareVersion`
If present, a release artifact will be created with the mapping below:
+-------------------+-----------------------------------+-----------------+----------------+
| SWH release field | Description | CodeMeta term | Fallback value |
+===================+===================================+=================+================+
| target | revision containing all metadata | X |X |
+-------------------+-----------------------------------+-----------------+----------------+
| target_type | revision | X |X |

| name | release or tag name (mandatory) | softwareVersion | X |
+-------------------+-----------------------------------+-----------------+----------------+

"target_type": "revision",
"target_url": "/api/1/revision/396b1ff29f7c75a0a3cc36f30e24ff7bae70bb52/"
}
Revision artifact
~~~~~~~~~~~~~~~~
The metadata sent with the deposit is included in the revision which affects
the hash computation, thus resulting in a unique identifier.
This way, by depositing the same content with different metadata, will result
in two different revisions in the SWH archive.
The date mapping
^^^^^^^^^^^^^^^
A deposit may contain 4 different dates concerning the software artifacts.
The deposit's revision will reflect the most accurate point in time available.
Here are all dates that can be available in a deposit:
+-------------------+-----------------------------------+-----------------------------------------------+
| dates | location | Description |
+===================+===================================+===============================================+
| reception_date | On SWORD reception (automatic) |the deposit was received at this ts |
+-------------------+-----------------------------------+-----------------------------------------------+
| complete_date | On SWH ingestion (automatic) |the ingestion was completed by SWH at this ts |
+-------------------+-----------------------------------+-----------------------------------------------+
| dateCreated | metadata in codeMeta (optional) |the software artifact was created at this ts |
+-------------------+-----------------------------------+----------------------+------------------------+
| datePublished | metadata in codeMeta (optional) |the software was published (contributed in HAL)|
+-------------------+-----------------------------------+----------------------+------------------------+
A visit targeting a snapshot contains one date:
+-------------------+----------------------------------------------+----------------+
| SWH visit field | Description | value |
+===================+==============================================+================+
| date | the origin pushed the deposit at this date | reception_date |
+-------------------+----------------------------------------------+----------------+
A revision contains two dates:
+-------------------+-----------------------------------------+----------------+----------------+
| SWH revision field| Description | CodeMeta term | Fallback value |
+===================+=========================================+================+================+
| date | date of software artifact modification | dateCreated | reception_date |
+-------------------+-----------------------------------------+----------------+----------------+
| committer_date | date of the commit in VCS | datePublished | reception_date |
+-------------------+-----------------------------------------+----------------+----------------+
A release contains one date:
+-------------------+----------------------------------+---------------+----------------+
| SWH release field |Description |CodeMeta term | Fallback value |
+===================+==================================+===============+================+
| date |release date = publication date |datePublished |reception_date |

* one dedicated temporary objstorage to store archives before loading
* one client to test the communication with SWORD protocol
Deposit reception schema
~~~~~~~~~~~~~~~~~~~~~~~~
* SWORD imposes the use of basic authentication, so we need a way to
authenticate client. Also, a client can access collections:
**deposit\_client** table: - id (bigint): Client's identifier - username
(str): Client's username - password (pass): Client's crypted password -
collections ([id]): List of collections the client can access
* Collections group deposits together:
**deposit\_collection** table: - id (bigint): Collection's identifier - name
(str): Collection's human readable name
* A deposit is the main object the repository is all about:
**deposit** table:
* id (bigint): deposit's identifier
* reception\_date (date): First deposit's reception date
* complete\_data (date): Date when the deposit is deemed complete and ready
for loading
* collection (id): The collection the deposit belongs to
* external id (text): client's internal identifier (e.g hal's id, etc...).
* client\_id (id) : Client which did the deposit
* swh\_id (str) : swh identifier result once the loading is complete
* status (enum): The deposit's current status
- As mentioned, a deposit can have a status, whose possible values are:
.. code:: text
'partial', -- the deposit is new or partially received since it
-- can be done in multiple requests
'expired', -- deposit has been there too long and is now deemed
-- ready to be garbage collected
'deposited' -- deposit complete, it is ready to be checked to ensure data consistency
'verified', -- deposit is fully received, checked, and ready for loading
'loading', -- loading is ongoing on swh's side
'done', -- loading is successful
'failed' -- loading is a failure
* A deposit is stateful and can be made in multiple requests:
**deposit\_request** table:
* id (bigint): identifier
* type (id): deposit request's type (possible values: 'archive', 'metadata')
* deposit\_id (id): deposit whose request belongs to
* metadata: metadata associated to the request
* date (date): date of the requests
Information sent along a request are stored in a ``deposit_request`` row.
They can be either of type ``metadata`` (atom entry, multipart's atom entry
part) or of type ``archive`` (binary upload, multipart's binary upload part).
When the deposit is complete (status ``deposited``), those ``metadata`` and
``archive`` deposit requests will be read and aggregated. They will then be
sent as parameters to the loading routine.
During loading, some of those metadata are kept in the ``origin_metadata``
table and some other are stored in the ``revision`` table (see `metadata
loading <#metadata-loading>`__).
The only update actions occurring on the deposit table are in regards of: -
status changing: - ``partial`` -> {``expired``/``deposited``}, -
``deposited`` -> {``rejected``/``verified``}, - ``verified`` -> ``loading`` -
``loading`` -> {``done``/``failed``} - ``complete_date`` when the deposit is

Scenarios for HAL- on HAL's platform
------------------------------------
The same procedure is used for all tests:
Software Author:
#. prepare content
#. fill out form
#. submit
HAL moderator:
#. review content submitted
#. check metadata fields on HAL
#. validate submission
SWH side:
1. check content in SWH:
- directory was created
- revision was created
- release was created when releaseNotes and softwareVersion was included (new feature!)
- origin corresponds to HAL url
2. check metadata fields on SWH (in revision)
3. check directory
4. check swh-id on HAL
5. check browsability when entering SWH artifact from HAL
6. check vault artifact recreation
7. access deposit's origin from SWH

Past known bugs:
- v2 problem, where swh-id from first version is kept in the second version
instead of the new swh-id.
- when deposit workers are down- error 500 is returned on HAL without real
explanation (because there is no error on SWH- deposit status
stays `deposited`).
