Get Wikidata property of one or more items as a tidy data frame

Description

Get Wikidata property of one or more items as a tidy data frame

Usage

tw_get_property(
  id,
  p,
  language = tidywikidatar::tw_get_language(),
  id_df = NULL,
  cache = NULL,
  overwrite_cache = FALSE,
  cache_connection = NULL,
  disconnect_db = TRUE,
  wait = 0
)

Arguments

id	A character vector, must start with Q, e.g. "Q180099" for the anthropologist Margaret Mead. Can also be a data frame of one row, typically generated with tw_search() or a combination of tw_search() and tw_filter_first().
p	A character vector, a property. Must always start with the capital letter "P", e.g. "P31" for "instance of".
language	Defaults to language set with tw_set_language(); if not set, "en". Use "all_available" to keep all languages. For available language values, see the dedicated Wikimedia page.
id_df	Default to NULL. If given, it should be a dataframe typically generated with tw_get(), and is used instead of calling Wikidata or using SQLite cache. Ignored when id is of length more than one.
cache	Defaults to NULL. If given, it should be given either TRUE or FALSE. Typically set with tw_enable_cache() or tw_disable_cache().
overwrite_cache	Logical, defaults to FALSE. If TRUE, it overwrites the table in the local sqlite database. Useful if the original Wikidata object has been updated.
cache_connection	Defaults to NULL. If NULL, and caching is enabled, tidywikidatar will use a local sqlite database. A custom connection to other databases can be given (see vignette caching for details).
disconnect_db	Defaults to TRUE. If FALSE, leaves the connection to cache open.
wait	In seconds, defaults to 0. Time to wait between queries to Wikidata. If data are cached locally, wait time is not applied. If you are running many queries systematically you may want to add some waiting time between queries.

Value

A tibble, corresponding to the value for the given property. A tibble of zero rows if no relevant property found.

Examples

# Who were the doctoral advisors - P184 - of Margaret Mead - Q180099?
advisors <- tw_get_property(id = "Q180099", p = "P184")
advisors

# tw_get_label(advisors)

# It is also possible to get one property for many id

if (interactive()) {
  tw_get_property(
    id = c(
      "Q180099",
      "Q228822"
    ),
    p = "P31"
  )

  # Or many properties for a single id

  tw_get_property(
    id = "Q180099",
    p = c("P21", "P31")
  )
}
