In isteves/emlspice: Converts EML to Tabular Formats

emlspice

Functions for translating EML into dataspice tabular formats:

• attributes.csv - explains each of the variables in the dataset
• biblio.csv - for spatial and temporal coverage, dataset name, keywords, etc.
• access.csv - for files and file types
• creators.csv - for data authors

Installation

devtools::install_github("isteves/dataspice")

Example

library(emlspice)
library(eml2)

eml_path <- system.file("LeConte_meteo_metadata.xml", package = "emlspice")
eml <- read_eml(eml_path)

Currently, there are 4 functions in the package, which each take an emld object (using eml2::read_eml and translates it to a dataspice table.

Here are the first few lines of each tabular format:

As part of that study we operated a Campbell Scientific weather station near the glacier terminus that recorded temperature, rain, wind speed and direction, humidity, incoming shortwave radiation, and barometric pressure. In addition, we also deployed HOBO temperature sensors and tipping bucket rain gauges at two locations: one was across the terminus from the base camp and the other was about 7 km upglacier from the terminus. | 2017-11-14 | NA | NA | This work is licensed under the Creative Commons Attribution 4.0 International License.To view a copy of this license, visit http://creativecommons.org/licenses/by/4.0/. | NA | LeConte Glacier, Alaska | 56.8281 | -132.3517 | 56.8281 | -132.3517 | NA | 2016-03-28 | 2017-09-18 | |
