How do I mount a specific version of a collection

arv-mount keep
cd keep/by_id/<collection_uuid>

will mount my collection.

But how do I mount a specific numerical version of my collection? e.g. version number 3


You can mount using the portable data hash. If you click on the version numbers, you can go to page for the version you want and grab the portable data hash (pdh). The idea is that you use the UUID for the most recent version of the data collection and the pdh for a specific version of the data collection. You can use the PDH the same way as the UUID when mounting keep as a file system (ie. use /keep/by_id/PDH). There is an example in the doc here: Arvados | Access Keep as a GNU/Linux filesystem. Hope this helps. Let us know if you have any other questions.
