Rate
|
|
****
|
|
Devicehub generates an rating for a device taking into consideration the
|
|
visual, functional, and performance.
|
|
|
|
.. todo:: add performance as a result of component fusion + general tests in `here <https://
|
|
github.com/eReuse/Rdevicescore/blob/master/img/input_process_output.png>`_.
|
|
|
|
A Workflow is as follows:
|
|
|
|
1. An agent generates feedback from the device in the form of benchmark,
|
|
visual, and functional information; which is filled in a ``Rate``
|
|
event. This is done through a **software**, defining the type
|
|
of ``Rate`` event. At the moment we have two rates: ``WorkbenchRate``
|
|
and ``PhotoboxRate``.
|
|
2. Devicehub gathers this information and computes a score that updates
|
|
the ``Rate`` event.
|
|
3. Devicehub aggregates different rates and computes a final score for
|
|
the device by performing a new ``AggregateRating`` event.
|
|
|
|
There are two **types** of ``Rate``: ``WorkbenchRate`` and
|
|
``PhotoboxRate``. Moreover, each rate can have different **versions**,
|
|
or different revisions of the algorithm used to compute the final score,
|
|
and Devicehub generates a rate event for **each** version. So, if
|
|
an agent fulfills a ``WorkbenchRate`` and there are 3 versions, Devicehub
|
|
generates 3 ``WorkbenchRate``. Devicehub understands that only one
|
|
version is the **official** and it will generate an ``AggregateRating``
|
|
only from the **official** version.
|
|
|
|
.. todo:: we should be able to disable a version without destroying code
|
|
|
|
In the future, Devicehub will be able to use different and independent
|
|
algorithms to calculate a ``Rate`` (not only changed by versions).
|
|
|
|
The technical Workflow in Devicehub is as follows:
|
|
|
|
1. In **T1**, the user performs a ``Snapshot`` by processing the device
|
|
through the Workbench. From the benchmarks and the visual and
|
|
functional ratings the user does in the device, the system generates
|
|
a ``WorkbenchRate``. With only this information,
|
|
the system generates an ``AggregateRating``, which is the event
|
|
that the user will see in the web.
|
|
2. In **T2**, the user takes pictures from the device through the
|
|
Photobox, and DeviceHub crates an ``ImageSet`` with multiple
|
|
``Image`` with information from the photobox.
|
|
3. In **T3**, an agent (user or AI) rates the pictures, creating a
|
|
``PhotoboxRate`` **for each** picture. When Devicehub receives the
|
|
first ``PhotoboxRate`` it creates an ``AggregateRating`` linked
|
|
to such ``PhotoboxRate``. So, the agent will perform as many
|
|
``PhotoboxRate`` as pictures are in the ``ImageSet``, and Devicehub
|
|
will link each ``PhotoboxRate`` to the same ``AggregateRating``.
|
|
This will end in **T3+Tn**, being *n* the number of photos to rate.
|
|
4. In **T3+Tn**, after the last photo is rated, Devicehub will generate
|
|
a new rate for the device: it takes the ``AggregateRating`` from 3.
|
|
and computes a rate from all the linked ``PhotoboxRate`` plus the
|
|
last available ``WorkbenchRate`` for that device.
|
|
|
|
If the agent in 3. is an user, Devicehub creates ``PhotoboxUserRate``
|
|
and if it is an AI it creates ``PhotoboxAIRate``.
|
|
|
|
The same ``ImageSet`` can be rated multiple times, generating a new
|
|
``AggregateRating`` each time.
|
|
|
|
.. todo:: which info does photobox provide for each picture?
|
|
|
|
Snapshot
|
|
********
|
|
The Snapshot sets the physical information of the device (S/N, model...)
|
|
and updates it with erasures, benchmarks, ratings, and tests; updates the
|
|
composition of its components (adding / removing them), and links tags
|
|
to the device.
|
|
|
|
When receiving a Snapshot, the DeviceHub creates, adds and removes
|
|
components to match the Snapshot. For example, if a Snapshot of a computer
|
|
contains a new component, the system searches for the component in its
|
|
database and, if not found, its creates it; finally linking it to the
|
|
computer.
|
|
|
|
A Snapshot is used with Remove to represent changes in components for
|
|
a device:
|
|
|
|
1. ``Snapshot`` creates a device if it does not exist, and the same
|
|
for its components. This is all done in one ``Snapshot``.
|
|
2. If the device exists, it updates its component composition by
|
|
*adding* and *removing* them. If,
|
|
for example, this new Snasphot doesn't have a component, it means that
|
|
this component is not present anymore in the device, thus removing it
|
|
from it. Then we have that:
|
|
|
|
- Components that are added to the device: snapshot2.components -
|
|
snapshot1.components
|
|
- Components that are removed to the device: snapshot1.components -
|
|
snapshot2.components
|
|
|
|
When adding a component, there may be the case this component existed
|
|
before and it was inside another device. In such case, DeviceHub will
|
|
perform ``Remove`` on the old parent.
|
|
|
|
Snapshots from Workbench
|
|
========================
|
|
When processing a device from the Workbench, this one performs a Snapshot
|
|
and then performs more events (like testings, benchmarking...).
|
|
|
|
There are two ways of sending this information. In an async way,
|
|
this is, submitting events as soon as Workbench performs then, or
|
|
submitting only one Snapshot event with all the other events embedded.
|
|
|
|
Asynced
|
|
-------
|
|
The use case, which is represented in the ``test_workbench_phases``,
|
|
is as follows:
|
|
|
|
1. In **T1**, WorkbenchServer (as the middleware from Workbench and
|
|
Devicehub) submits:
|
|
|
|
- A ``Snapshot`` event with the required information to **synchronize**
|
|
and **rate** the device. This is:
|
|
|
|
- Identification information about the device and components
|
|
(S/N, model, physical characteristics...)
|
|
- ``Tags`` in a ``tags`` property in the ``device``.
|
|
- ``Rate`` in an ``events`` property in the ``device``.
|
|
- ``Benchmarks`` in an ``events`` property in each ``component``
|
|
or ``device``.
|
|
- ``TestDataStorage`` as in ``Benchmarks``.
|
|
- An ordered set of **expected events**, defining which are the next
|
|
events that Workbench will perform to the device in ideal
|
|
conditions (device doesn't fail, no Internet drop...).
|
|
|
|
Devicehub **syncs** the device with the database and perform the
|
|
``Benchmark``, the ``TestDataStorage``, and finally the ``Rate``.
|
|
This leaves the Snapshot **open** to wait for the next events
|
|
to come.
|
|
2. Assuming that we expect all events, in **T2**, WorkbenchServer
|
|
submits a ``StressTest`` with a ``snapshot`` field containing the
|
|
ID of the Snapshot in 1, and Devicehub links the event with such
|
|
``Snapshot``.
|
|
3. In **T3**, WorkbenchServer submits the ``Erase`` with the ``Snapshot``
|
|
and ``component`` IDs from 1, linking it to them. It repeats
|
|
this for all the erased data storage devices; **T3+Tn** being
|
|
*n* the erased data storage devices.
|
|
4. WorkbenchServer does like in 3. but for the event ``Install``,
|
|
finishing in **T3+Tn+Tx**, being *x* the number of data storage
|
|
devices with an OS installed into.
|
|
5. In **T3+Tn+Tx**, when all *expected events* have been performed,
|
|
Devicehub **closes** the ``Snapshot`` from 1.
|
|
|
|
Synced
|
|
------
|
|
Optionally, Devicehub understands receiving a ``Snapshot`` with all
|
|
the events in an ``events`` property inside each affected ``component``
|
|
or ``device``.
|
|
|
|
ToDispose and DisposeProduct
|
|
****************************
|
|
There are four events for getting rid of devices:
|
|
|
|
- ``ToDispose``: The device is marked to be disposed.
|
|
- ``DisposeProduct``: The device has been disposed. This is a ``Trade``
|
|
event, which means that you can optionally ``DisposeProduct``
|
|
to someone.
|
|
- ``RecyclingCenter`` have two extra special events:
|
|
- ``DisposeWaste``: The device has been disposed in an unspecified
|
|
manner.
|
|
- ``Recover``: The device has been scrapped and its materials have
|
|
been recovered under a new product.
|
|
|
|
.. note:: For usability purposes, users might not directly perform
|
|
``Dispose``, but this could automatically be done when
|
|
performing ``ToDispose`` + ``Receive`` to a ``RecyclingCenter``.
|
|
|
|
.. todo:: Ensure that ``Dispose`` is a ``Trade`` event. An Org could
|
|
``Sell`` or ``Donate`` a device with the objective of disposing them.
|
|
Is ``Dispose`` ok, or do we want to keep that extra ``Sell`` or
|
|
``Donate`` event? Could dispose be a synonym of any of those?
