element_texts: Read element texts from an Omeka item

In lmullen/omekaR: omekaR: A client for the Omeka API

Description

Omeka items as returned by the API have a deeply nested structure. Most of the interesting information is stored in the element texts. This function provides a convenient way of accessing those element texts. Calling this function on an Omeka item returns a named character vector of all the element texts. Optionally you can pass a character vector to filter the output so the function returns only a particular kind of metadata, e.g., "Title".

Usage

element_texts(item, filter)

Arguments

item	An Omeka item as a list
filter	Which element texts to return, as a character vector

Value

A named character vector of element texts

Examples

omeka_endpoint("http://20.rrchnm.org/api")
# Get the Papers of the War Department project item
war_dept <- omeka_get("items", 197)
element_texts(war_dept)
element_texts(war_dept, "Title")
element_texts(war_dept, "Content Experts")
element_texts(war_dept, c("Start Date", "End Date"))
