Canvasses

This page defines the Canvass resource.

A canvass occurs when one person attempts to contact another person for the purpose of obtaining data about that person. For example, a canvasser visits a voter’s home and asks the voter whether she intends to vote in the next election; or, a campaign staffer calls a volunteer to ask whether he intends to attend the candidate’s upcoming kick-off event. The person being contacted is known as the “target” of the canvass, and the target may have Answers or Taggings applied to them as a result of the canvass. Alternatively, the target may have a non-canvass result (e.g. “not home”) applied to them. Canvasses can be part of a larger Canvassing Effort, representing a day of canvassing, for example.

It is not necessary to create a Canvass in order to create an Answer or Tagging for a Person. However, a Canvass can provide useful information about how the Answer or Tagging was collected, which may prove valuable for future organizing purposes.

Sections

Endpoints and URL structures

OSDI does not specify specific endpoints and link structures for compliant systems to use. Rather, because OSDI is a HAL+JSON API, endpoints and structures are defined in the links section of each returned resource, starting with the API Entry Point link.

HAL’s link structure lets an API consumer move through API levels, resources, and collections by parsing and following links. While most systems will not change the value of their links often and obey RESTful design principles, the value of each link when that resource is retrieved is the only canonical value, and it can change at any time.

The link relation label for an Canvass resource is osdi:canvass for a single Canvass resource or osdi:canvasses for a collection of Canvass resources.

Fields

The field names for this resource, with standard names, punctuation and capitalization, and values where appropriate.

Note: As with the entire OSDI specification, the specific fields a compliant system implements will vary between each system, as will the fields each system requires when creating or updating resources, which fields are writeable, and the operations you are allowed to perform on each resource.

Common Fields

A set of common fields that appear on all resources is included first, for reference.

Name Type Description
identifiers strings[] A unique string array of identifiers in the format [system name]:[id]. See the general concepts document for more information about identifiers.
created_date datetime A read-only property representing the date and time the resource was created on the local system.
modified_date datetime A read-only property representing the date and time the resource was last modified on the local system.

Control Headers

An “osdi:control” JSON object may contain common OSDI control headers which can be used on an OSDI POST, PUT, PATCH, Helper or other function calls to modify server behavior. Read More

Name Type Description
return_response boolean Defaults to true, if specified as false, the operation does not need to return the resource representation in the response

Canvass Fields

Name Type Description
origin_system string A human readable identifier of the system where this canvass was created. (ex: “OSDI System”)
action_date string The date and time the canvass was attempted.
contact_type string A code indicating the method by which the person was contacted. For example: “in-person”
input_type string A code indicating the method by which the canvass is being input into the system. For example: “mobile”
success boolean True if the target was successfully contacted, False otherwise.
status_code string A code indicating the status of the contact attempt. For example: “not-home” indicates that the contact failed because the target was not home, while “success” indicates that the target was contacted successfully. An empty or missing value for status_code should be assumed to mean that the contact was successful.

The links associated with this resource, available in the links section of the resource. Links that are part of the OSDI spec are typically prefixed with the osdi: namespace to aid in curie matching and readability.

Note: As with the entire OSDI specification, the specific links a compliant system supplies will vary between each system. In addition, systems may choose to embed a linked resource directly in the response in addition to linking to it in the links section, using the standard _embedded syntax described in the general overview documentation.

Name Type Description
self Canvass* A self-referential link to the Canvass.
canvasser Person* A link to a single Person resource representing the person who made the contact.
target Person* A link to a single Person resource representing the person who was contacted.
answers Answers[]* A link to the collection of Answers to Questions posed during the Canvass.
taggings Taggings[]* A link to the collection of Taggings applied as a result of the Canvass.
canvassing_effort Canvassing Effort* A link to the Canvass Effort this Canvass was part of.

Helpers

Helpers faciliate combined creation operations (POST) that are commonly performed by users. Each resource may have one or more associated helpers, which perform different operations and have separate syntax. Some initial OSDI implementations may only support helpers, rather than full RESTful access.

The helpers that operate on this resource are described in the table below. Click on the helper to view its documentation and syntax.

Name Description
record_canvass_helper Allows the creation of a Canvass and associated Answers and Taggings.

Scenario: Modifying a Canvass (PUT)

You can update an Canvass by calling a PUT operation on that canvass’s endpoint. Your PUT should contain fields that you want to update. Missing fields will be ignored by the receiving system. Systems may also ignore PUT values, depending on whether fields you are trying to modify are read-only or not. You may set an attribute to nil by including the attribute using nil for value.

Note: Modifying members of an array separately is not supported. To change the contents of an array, first GET the current contents and then PUT back only those you wish to keep.
