This repository contains code that requests all metadata from all HAPI servers daily and creates additional metadata and plots. See etc/crontab.sh for commands that are executed.

• abouts.py updates abouts.json, which contains the master list of HAPI servers; see also the README of its repository.

• catalogs.py reads /catalog responses (which contain a list of datasets) from each server in abouts.json. The /info response for each dataset from each server is then requested. The catalog response for each server is stored in a subdirectory of hapi-server.org/meta/catalogs. The /info responses for each dataset are stored in a subdirectory of hapi-server.org/meta/infos. The file catalogs-all.json contains all /catalog and /info responses in a single file.

• availability.py creates dataset availability plots based on the {start,stop}Date found in the dataset /info responses. Plots are stored at hapi-server.org/meta/availabilities/, and they are visible at hapi-server.org/servers when selecting a server and clicking "View SERVER Time Range Coverage."

• spase.py creates partial SPASE records for all datasets of all servers. It uses spase.json for configuration information. The output is stored in https://hapi-server.org/meta/spase/.
