I believe every field has its own standards.
For instance in astronomy the standard for transport of image data is
FITS (basic FITS). The de facto standard for transport of other data
is a set of extension to FITS (which unfortunately are too flexible and
relaxed to be an unique standard ... let's say they ensure interoperability
more than portability).
On the other hand what is a great thing for *transport* may not be a
great thing as work format. Most astronomical packages therefore convert
into a native format (OS dependent, that's often more efficient). I have my
own too.

The advantage of IDL is that is is not a package but a language, and
can be adapted very flexibly to import any kind of data (whose format
is documented). E.g. I know there is an "astrolib" to read FITS, and
I have my own little set of routines to read my own format.
I've also been told by a colleague that one can save an IDL session
under a given OS, move the saved binary file to a different OS, restore
it and continue working as one just resumes the session. But probably
this is barely relevant to the present issue.
