This vignette only highlights the most basic functions and shows a way to get to your data quickly.
Connection: Example
conn <- connect_idaifield(pwd = "hallo", project = "rtest")
db <- get_idaifield_docs(connection = conn)
index <- get_uid_list(db)Selection and Simplify: Example
Using the following few lines and all default arguments while selecting from the whole database:
library(dplyr)
pottery <- db %>%
idf_select_by(by = "category", value = "Pottery") %>%
# Note: simplify_idaifield() needs the index of the complete project database
# as a lookup-table to replace all UUIDs with their identifiers
simplify_idaifield(uidlist = index) %>%
idaifield_as_matrix() %>%
as.data.frame()Query and Simplify: Example
Or using the following few lines with direct queries to the database:
pottery <- idf_query(connection = conn,
field = "type",
value = "Pottery") %>%
simplify_idaifield(uidlist = index) %>%
idaifield_as_matrix() %>%
as.data.frame()See also: ?idf_index_query, ?idf_query and
?idf_json_query.
Language Lookup: Example
Downloading translations and converting them into a lookup table:
core_lang_list <- download_language_list(project = "core", language = "de")
pergamon_lang_list <- download_language_list(project = "Pergamon", language = "de")
config_lang_list <- get_configuration(attr(db, "connection"))
config_lang_list <- config_lang_list$languages
lookup <- get_language_lookup(core_lang_list, language = "de")
lookup <- rbind(lookup, get_language_lookup(pergamon_lang_list, language = "de"))
lookup <- rbind(lookup, get_language_lookup(config_lang_list, language = "de"))
head(lookup)
