Load attribute information from a entity attribute yaml or csv file

The read_attributes_file function reads an entity's attribute details from a "entity name"_attrs.yaml or "entity name"_attrs.csv file in the working directory - the details of which are incorporated into the EML metadata for that entity.

Usage

read_attributes_file(string_pointer, entity_id)

Arguments

string_pointer

(character) The quoted name of the data entity.

entity_id

(character) Quoted identifier of the data object that is being described, this will usually be the name or hash of the data table (or otherwise) of which the attribute is associated.

Value

A list of a list of attributes and column classes

Details

The read_attributes_file function reads an entity's attribute details from a "entity name"_attrs.yaml or "entity name"_attrs.csv file in the working directory - the details of which are incorporated into the EML metadata for that entity.

Note

Recent versions of the capeml package generate attribute (and factor) metadata files in yaml format; the read_attributes_file function will look also for attributes files in csv format to accommodate older projects.

The read_attributes_file function is intended primarily as a helper to other functions in the capeml ecosystem (notably read_attributes and read_raster_attributes) so is not meant to be called directly (but can be).
