Hi everybody.
I was wondering if there is a clean way for accessing metadata provided
via EFS mechanisms.
I'll try to explain better my use case. I successfully wrote a
filesystem for accessing a remote system. The openInputStream and
openOutputStream allow me to interact with the remote data by reading
and saving it.
Now my problem is that the remote data (that is actually a document)
also has some metadata associated (e.g., the version, author, etc.).
I was thinking of providing, through the openInputStream method, both
the content and the metadata as the result. However I would like to keep
things separated.
The solution I found was to ask to EFS to give me the FileStore
associated to the current edited URI. Then I cast this FileStore to its
actual type that will have some extra methods for accessing the
metadata, and I use them for getting what I want.
This solution works fine. However it seems a bit dirty since I have to
"open" the implementation of my filesystem by exporting all the
FileStores that, normally, should be "internal".
Do you know another way for doing what I am trying to do in a clean way?
Thank you.

You may be able to use IFileInfo#getStringAttribute for this kind of
metadata.
