Databrary is a data library, one specialized for storing and sharing
video with a restricted audience of institutionally approved
researchers. In this vignette, we’ll see how to use
databraryr to access data.
We’ll start simply. Let’s download a test video from volume 1 on Databrary.
The download_video() function handles this for us.
Running it with the default parameters downloads a simple test video
with numbers than increment. The file is stored in a temporary directory
created by the file system using the function tempdir().
The download_video() function returns a character string
with the full file name.
The function returns a path to the video on your file system. The
file name chosen, since we didn’t specify one, is the session number
9807, an underscore, the file/asset number 1,
another underscore, and a time stamp.
Note: You can navigate to the location where we’re downloading files by opening the following URL in your browser: https://databrary.org/volume/1/slot/9807
Depending on your operating system, the following commands may open the file so that you can play it with your default video player.
Or, you can navigate to the temporary directory to open and play the
video manually. Use tempdir() to find the directory where
test.mp4 is stored.
Now, let’s see what other files are shared in volume 1, not just those in session (slot) 9807. This takes a moment to run because there are many files in this volume.

#> 128 video/mp4 mp4 MPEG-4 videoIf we log-in using the commands described in authorized users, and provide the
function with a valid (non-NULL) httr2 request parameter,
the following function call would show files and data that are
restricted to authorized users:
Obviously, you would need to supply a vol_id for some
other non-public dataset for this to return useful information.
The list_volume_assets() command returns a data frame we
can manipulate using standard R commands. Here are the variables in the
data frame.
vol1_assets <- databraryr::list_volume_assets()
names(vol1_assets)
#> [1] "asset_id" "asset_format_id" "asset_duration" "asset_name"
#> [5] "asset_permission" "asset_size" "session_id" "session_date"
#> [9] "session_release" "format_mimetype" "format_extension" "format_name"Or, if you use the R (> version 4.3) ‘pipe’ syntax:
databraryr::list_volume_assets() |>
names()
#> [1] "asset_id" "asset_format_id" "asset_duration" "asset_name"
#> [5] "asset_permission" "asset_size" "session_id" "session_date"
#> [9] "session_release" "format_mimetype" "format_extension" "format_name"The magrittr package pipe (‘%>%’) also works (as of
databraryr v0.6.2).
The asset_format_id variable tells us information about
the type of the data file.
But this isn’t especially informative since the
asset_format is a code, and we don’t really know what
-800 or 6 or the other numbers refer to. To
decode it, we create a data frame of all the file formats Databrary
currently recognizes.
db_constants <- databraryr::assign_constants()
formats_df <- purrr::map(db_constants$format, as.data.frame) |>

video. There are lots of those in Volume 1. We see that6 is
a PDF document.
As of 0.6.0, list_volume_assets() adds this information
to the data frame.
We can summarize the number of files using the
stats::xtabs() function:
stats::xtabs(~ format_name, data = vol1_assets)

#> 2 1
#> MPEG-1 or MPEG-2 audio layer III MPEG-4 video
#> 2 75
#> Portable document Portable network graphics
#> 47 1So, there are lots of videos and PDFs to examine in volume 1. Here is a table of the ten longest videos.

Imagine you are interested in knowing more about this volume, the people who created it, or the agencies that funded it.
The list_volume_owners() function returns a data frame
with information about the people who created and “own” this particular
dataset. The function has a parameter this_vol_id which is
an integer, unique across Databrary, that refers to the specific
dataset. The list_volume_owners() function uses volume 1 as
the default.
databraryr::list_volume_owners()
#> # A tibble: 3 × 2
#> owner_name party_id
#> <chr> <int>
#> 1 Adolph, Karen 5
#> 2 Gilmore, Rick O. 6
#> 3 Staff 308The command (and many like it) can be “vectorized” using the
purrr package. This let’s us generate a tibble with the
owners of the first fifteen volumes.

#> 14 Messinger, Daniel 70As of 0.6.0, the get_volume_by_id() returns a list of
all data about a volume that is accessible to a particular user. The
default is volume 1.
vol1_list <- databraryr::get_volume_by_id()
names(vol1_list)
#> [1] "id" "name" "body" "doi"
#> [5] "creation" "owners" "permission" "publicsharefull"
#> [9] "publicaccess" "access" "citation" "links"
#> [13] "funding" "top" "tags" "excerpts"
#> [17] "comments" "records" "containers" "metrics"
#> [21] "state"Let’s create our own tibble/data frame with a subset of these variables.
vol1_df <- tibble::tibble(id = vol1_list$id,
name = vol1_list$name,
doi = vol1_list$creation,
permission = vol1_list$permission)
vol1_df
#> # A tibble: 1 × 4

#> 1 1 Databrary sponsored workshops and events 2013-01-11T10:26:40Z 1The permission variable indicates whether a volume is
visible by you, and if so with what privileges.
So, if you are not logged-in to Databrary, only data that are visible
to the public will be returned. Assuming you are not logged-in,
the above commands will show volumes with permission equal
to 1. The permission field derives from a set of constants
the system uses.
db_constants <- databraryr::assign_constants()
db_constants$permission
#> [[1]]
#> [1] "NONE"
#>
#> [[2]]
#> [1] "PUBLIC"
#>
#> [[3]]
#> [1] "SHARED"
#>
#> [[4]]
#> [1] "READ"
#>
#> [[5]]
#> [1] "EDIT"
#>
#> [[6]]
#> [1] "ADMIN"The permission array is indexed beginning with 0. So the
1th (1st) value is “PUBLIC”. So, the 1 means that the
volumes shown above are all visible to the public, and to you.
Volumes that you have not shared and are not visible to the public,
will have permission equal to 5, or “ADMIN”. We can’t
demonstrate this to you because we don’t have privileges on the same
unshared volume, but you can try it on a volume you’ve created but not
yet shared.
Other functions with the form list_volume_*() provide
information about Databrary volumes. For example, the
list_volume_funding() command returns information about any
funders listed for the project. Again, the default volume is 1.
databraryr::list_volume_funding()
#> # A tibble: 2 × 4
#> funder_id funder_name funder_award vol_id
#> <int> <chr> <chr> <dbl>
#> 1 100000001 National Science Foundation (NSF) BCS-1238599 1
#> 2 100000071 National Institute of Child Health and Human De… U01-HD-0765… 1The list_volume_links() command returns information
about any external (web) links that have been added to a volume, such as
to related publications or a GitHub repo.
databraryr::list_volume_links()
#> # A tibble: 2 × 3
#> link_name link_url vol_id

using databraryr, but this should get you started.
As of 0.6.3, it’s possible to download multiple files. The following
set of commands downloads all of the ‘csv’ files in volume 1 using the
output from list_volume_session_assets() (when you have a
volume ID and a session ID) or list_session_assets() when
you have only the session ID. The code below creates a new directory
based on the session/slot ID (9807). The function returns the file path
to the downloaded files.
