[Loc-xferutils-mail] Preserving directory structure

[Calvin W. <cal...@ha...>]

Hello,

Is there a way to preserve the path structure up to the folder to be
bagged?  Such as if I had an input path like
"C:\users\calvin\documents\stuff," I want the folders inside the bag to
also be something like "C\users\calvin\documents\stuff."

Is there also a way to keep duplicate folders with the same name that are
in different paths separate?

Thanks

Hi,

1. regarding your first question:

I suppose you want something like this...:

bag/ 
  manifest-md5.txt
  data/
    C\users\calvin\documents\stuff

...in order to preserve some sort of "history" (where was it originally stored?)
of the filename/directory.

No, this is not possible: a bag is simply a directory,
to be dragged from source to destination, like
any other directory. That destination can be another
computer, but also another directory on the same
filesystem.

Even a zip does not preserve the full path of the source files, 
because unzipping a file like "C\users\calvin\documents\stuff"
would write the file to "C:\users\calvin\documents\stuff" instead
of to the same directory of the zip file.

I would recommend describing this kind of information
in a mets.xml:

http://www.loc.gov/standards/mets/

It's an international metadata standard for describing files
and their corresponding metadata (and so also their history).

I'm not sure if I understood your first question correctly ;-)

2. and your second question:

"Is there also a way to keep duplicate folders with the same name that are in different paths separate?"

Mm, I suspect you tried to add source directories with the same name
(but in different parent directories) to the bag? That will not work.
For they are added to the "root" of the bag.
It's like copying those directories to the same destination directory
(they would overwrite each other).

Simply prepare the directory structure the way
you want it to look in the bag, and then add
this new directory to the bag.

Actually, preserving the paths that way is generally an option in
many compression tools. Some people intend for an archive to be
expanded at the root of a filesystem, or otherwise just want the
archive to reflect the entire hierarchy for whatever reason.

I wouldn't say it's "not possible", but I don't think it's provided
by default in any official BagIt utilities or libraries. You'll just
need to implement that logic yourself somehow.

you're right. Had forgotten about that;-)

But bagging is al about "transfer" of data from one
computer to the other, not about restoring of
data to the same locations they were before
(for that is the reason their paths preserved
in a zip).

Bagit is basically just a directory structure. ZIP is only
used as a way of transferring this bag.

See "serialization" of bags: http://www.digitalpreservation.gov/documents/bagitspec.pdf
