Hello,

What is the best way to programatically access experiments? I want to write a script which goes through all of the experiments on a particular ref e.g. HEAD, and collects some data / information from the files there. The files could be git or dvc tracked. I have lots of output from my pipeline, so it is more than I would want to put in a metrics json. It seems like DVCFileSystem ([DVCFileSystem](https://dvc.org/doc/api-reference/dvcfilesystem)) might do this? Would I just need to get a list of all the experiment revs, then loop over them and create a DVCFileSystem for each one?

Thanks,  
Greg

Hey Greg,

Currently there is no exp-specific api like that, but if all you need is an fs-like interface to experiments then yes, creating a DVCFileSystem for each rev would do the trick. Please let us know how it goes for you or if you’ll run into any problems.

Thanks for the advice.

This is what I ended up doing:

```auto
repo = Repo(".")
# determine current branch
branch = repo.scm.active_branch()
# get experiments on this commit
experiments = repo.experiments.ls()[branch]
for exp_name in experiments:
    print(f"collecting data for {exp_name}")
    # make dvc file system for this experiment
    fs = DVCFileSystem(rev=exp_name)

```

then accessing files, e.g. `pandas.read_csv` through the dvc fs.
