Exploring ODC data

The KM3Store serves as interface to the data available in the open data center (ODC). Information is retrieved on first use of the KM3Store from the ODC and stored in cache.

from openkm3.store import KM3Store
store = KM3Store()
INFO:root:Loaded catalog from cache.

If information should be reloaded from the ODC, update the catalog.

store.update_catalog()
store.list() # lists all available collections
INFO:root:Updated catalog!
