Usage

odata_entitylist_service_get(
  pid = get_default_pid(),
  did = "",
  url = get_default_url(),
  un = get_default_un(),
  pw = get_default_pw(),
  retries = get_retries(),
  odkc_version = get_default_odkc_version(),
  orders = get_default_orders(),
  tz = get_default_tz()
)

Arguments

pid

The numeric ID of the project, e.g.: 2.

Default: get_default_pid.

Set default pid through ru_setup(pid="...").

See vignette("Setup", package = "ruODK").

did

(chr) The name of the Entity List, internally called Dataset. The function will error if this parameter is not given. Default: "".

url

The ODK Central base URL without trailing slash.

Default: get_default_url.

Set default url through ru_setup(url="...").

See vignette("Setup", package = "ruODK").

un

The ODK Central username (an email address). Default: get_default_un. Set default un through ru_setup(un="..."). See vignette("Setup", package = "ruODK").

pw

The ODK Central password. Default: get_default_pw. Set default pw through ru_setup(pw="..."). See vignette("Setup", package = "ruODK").

retries

The number of attempts to retrieve a web resource.

This parameter is given to RETRY(times = retries).

Default: 3.

odkc_version

The ODK Central version as a semantic version string (year.minor.patch), e.g. "2023.5.1". The version is shown on ODK Central's version page /version.txt. Discard the "v". ruODK uses this parameter to adjust for breaking changes in ODK Central.

Default: get_default_odkc_version or "2023.5.1" if unset.

Set default get_default_odkc_version through ru_setup(odkc_version="2023.5.1").

See vignette("Setup", package = "ruODK").

orders

(vector of character) Orders of datetime elements for lubridate.

Default: c("YmdHMS", "YmdHMSz", "Ymd HMS", "Ymd HMSz", "Ymd", "ymd").

tz

A timezone to convert dates and times to.

Read vignette("setup", package = "ruODK") to learn how ruODK's timezone can be set globally or per function.

Value

An S3 class odata_entitylist_service_get with two list items:

  • context The URL for the OData metadata document

  • value A tibble of EntitySets available in this EntityList

Details

ODK Central presents one OData service for every Dataset (Entity List) as a way to get an OData feed of Entities. To access the OData service, add .svc to the resource URL for the given Dataset (Entity List).

The Service Document provides a link to the main source of information in this OData service: the list of Entities in this Dataset, as well as the Metadata Document describing the schema of this information.

This document is available only in JSON format.
