# Panoptes API
Panoptes API is a *crowdsourcing system* based on serving _subjects_,
images or other media, to _volunteers_ and asking them to _classify_
the _subject_ based on a defined _workflow_ for the _subject_ type.
# Naming Conventions
Resources attributes related to human readable names for resources
follow a common convention.
+ name - the url_escaped, downcased, and underscored unique identifier that can be used to construct client URLs
+ display_name - a non-unique identifier that can contain any character. Used to quickly describe a resource.
+ title - a non-unique identifier that can contain any character. Maybe translated if a client requests a representation of a resource in another language
# Authentication
Panoptes API provides an OAuth 2.0 authentication mechanism. (TODO:
Describe Authentication Workflow).
# Headers
Panoptes API sometime requires specific headers to be sent as part of requests.
All requests should set `Accept: application/vnd.api+json; version=1`. You will receive a `404 Not Found` without it.
All PUT and POST requests should set `Content-Type: application/vnd.api+json; version=1` or `Content-Type: application/json`. You will receive a `415 Unsupported Media Type` without one of those two headers.
All PUT and DELETE requests should set the `If-Match` header to the value of the `ETag` header of the request where the resource was originally retrieved. You will receive a `428 Precondition Required` without the header and a `412 Precondition Failed` if the etags do not match.

### List all classifications [GET]
Only lists classifications the active user has made or projects the user has edit permissions for.
Classifications have special collection routes that indicate the scope you would like to retrieve.
Possible options are:
+ '/' default, will fetch the current user's past complete classifications.
+ '/incomplete' will fetch the current user's past incomplete classifications.
+ '/project' will fetch classifications from projects a user has 'edit' permissions for
+ '/gold_standard' will fetch gold standard classifications for all marked workflows
Any of the scopes may be further filtered using the *project_id*, *workflow_id*
and *user_group_id* parameters.
+ Parameters
+ page (optional, integer) ... index of the collection page, 1 is default
+ page_size (optional, integer) ... number of items on a page. 20 is default
+ sort (optional, string) ... fields to sort collection by. updated_at is default
+ project_id (optional, integer) ... only retrieve classifications for a specific project
+ user_group_id (optional, integer) ... only retrieve classifications for a specific user group
+ include (optional, string) ... comma separated list of linked resources to return with the collection
+ last_id (optional, integer) ... only classifications with ids greater than `last_id` will be returned
(`/project` only, requires project_id)

### Create a Classification [POST]
Create a classification by providing a JSON-API formatted object, that
must include _metadata_, _annotations_ and a _links_ hash. Optionally, it
may include the _completed_ field, which if not included defaults to true.
The completed field is used to store half-completed classifications, so the user
can later continue from where they stopped.
The _links_ hash must contain a _subjects_ hash, a _project_ and a _workflow_.
The _metadata_ hash must contain all the keys specified in the example.
Please note, the _workflow_version_ should be the value returned from the
specific workflow representation. The annotations array must be in the
format specified in the example, i.e. an array of objects, containing a _task_ and a _value_.
The _task_ can be anything and must not necessarily align with the tasks of the workflow
(even though that is generally not advised).

Subjects allow a special sort option called 'cellect' that produces a
list of subjects that have not been seen by the active user.
When the cellect sort is used, *workflow_id* is a required parameter.
Subjects also allow an 'queued' sort, which will return a random
subset of subjects have a been queued for a particular user to
classify, usually for expert classifiers.

[Subject Collection][]
### Create a Subject [POST]
A *locations* attribute and a project link are required.
To have the Zooniverse host your media resources the *locations* array
should have the mime-types of the subject's associated media,
e.g `"locations":["image/png", "image/jpeg", "image/png"]`,
note the locations mime types are stored in order.
The create response will contain signed s3 urls the client may make a PUT
request containing the media to. The signed urls will be valid for 20 minutes.
Please take the order of the returned s3 urls into account when PUT'ing
local media resources to the remote location.
To use your own hosted media resources the *locations* array
should be comprised of objects that represent the mime-type and the hosted URL
of the subject's associated media,
e.g. `"locations":[
{"image/png": "https://your.s3_account.com/subjects/1.png"},
{"image/jpeg": "https://your.s3_account.com/subjects/1.jpg"}
]`.
The *metadata* attribute is optional.
