Tips for working with large datasets

[laijasmine]

Complementing #259

• Create a central table for all the attributes across all datasets and either use filter or left_join to refine what is needed

• Use references

• use relevant parts of the file name to help construct a description using dplyr::case_when , tools::file_path_sans_ext(), and stringr::str_extract

• use selectMember to help you grab the correct pids to use
  eg. zipId <- selectMember(dp, name="sysmeta@formatId", value="application/vnd.shp+zip")

• use for loops or purrr::map to help iterate through entities
