R Documentation

`createMetadata` - Create master metadata table from objectstore data repository

Description

This function creates the metadata from a hierarchical data structure. It assumes a structure of: file_location/<taxa>/<data_type>/<dataset_name>. It assumes that all dataset names contain the year of entry (in the format 2019 or 2019.2 for the second dataset in 2019). It also assumes that there is an equivalent folder at: file_location/<taxa>/input_data/<dataset_name> Which contains the input data. A lot of the parameters are hardcoded, and as such it is unlikely to return perfect metadata if the structure of outputs is altered. This takes about an hour to run as of 12 May 2021. You can pass it the previous metadata as a parameter, so it will not run metadata collection on any old datasets.

Usage

createMetadata(file_location, oldMetadata = NULL)

Arguments

`file_location`	Path to root directory of data outputs on object store
`oldMetadata`	Dataframe object previously created by this function. All rows of data in this object will not be run. Note that if data has changed in any of the datasets contained within the old metadata dataframe, these will not be re-run. Defaults to NULL (metadata will be calculated for all datasets in the object store)
