The database manager is an API within OmnipathR which is able to load various datasets, keep track of their usage and remove them after an expiry period. Currently it supports a few Gene Ontology and UniProt datasets, but easily can be extended to cover all datasets in the package.

To see a full list of datasets call the omnipath_show_db function:

## # ℹ 14 more rowsIt returns a tibble where each dataset has a human readable name and a key which can be used to refer to it. We can also check here if the dataset is currently loaded, the time it’s been last used, the loader function and its arguments.
Datasets can be accessed by the get_db function. Ideally you should call
this function every time you use the dataset. The first time it will be
loaded, the subsequent times the already loaded dataset will be returned.
This way each access is registered and extends the expiry time. Let’s load
the human UniProt-GeneSymbol table. Above we see its key is up_gs.
up_gs <- get_db('up_gs')

Looking again at the datasets, we find that this dataset is loaded now and
the last_used timestamp is set to the time we called get_db:

## # ℹ 20,459 more rowsThe default expiry of datasets is given by the option omnipath.db_lifetime.
By calling omnipath_save_config this option is saved to the default config
file and will be valid in all subsequent sessions. Otherwise it’s valid only
in the current session.
options(omnipath.db_lifetime = 600)
omnipath_save_config()The built-in dataset definitions are in a JSON file shipped with the package. Easiest way to see it is by the git web interface.
Currently no API available for this, but it would be super easy to implement. It would be matter of providing a JSON similar to the above, or calling a function. Please open an issue if you are interested in this feature.
