Thanks Nicklas,
Sorry I hadn't seen the existing functionality - we will check it all out
and get back to you soon!

Hi Nicklas et al,
Getting up to speed with BASE3 and NGS - so far all seems good - even
upgrading our own API code has gone smoother than I expected. Thanks!
Great to hear that it is going well.
A possible feature request for general discussion:
Would it be possible to have placeholder files in the BASE file system
which weren't on disk but had an FTP location stored in the DB? It
would be a bit like the current offline option but for our use case
(fastq and BAM files stored elsewhere and never processed by BASE3 or
plugins) we would never even upload the files in the first place (I
can't find a way to create a file that is offline from the start).
The debate for other users/devs would be: should BASE automatically
retrieve the files when needed? I say no need for that - treat them
like offline files are currently (if I understand correctly how offline
files work).
There is already the *external files* feature. It can accessed with New
URL in the BASE file manager. It's not the same as an *offline* file
since by default BASE will try to check if it exists and download some
metadata (such as size and modification date). And BASE will also
retrieve the file if is requested by a plug-in or a user tries to
download or view it.
The external files feature is pluggable and the BASE core only provide
support for files that can be accessed with http or https. In theory it
is possible to register unsupported URLs (eg. ftp://...) but I guess
error messages will popup here and there.
As it happens, we discussed a similar problem last week. Up until now,
our approach has been to simply store the file path as an annotation on
bioassay items. In the future we'll need to provide access for external
researchers to our data, but we really don't want to have them on our
internal file servers so the idea is to let BASE act as a proxy.
So, I am currently working on an extension that add support for
accessing external files via FTP, FTPS and SFTP (see
http://baseplugins.thep.lu.se/wiki/net.sf.basedb.xfiles). I might be
able to release a first version later this week if you want to try it.
If you prefer the *offline* files feature there is unfortunately no
support in the GUI for creating offline files without first uploading
them. A possible solution would be to modify the New URL dialog to
make the URL field optional, and use this to decide between
offline/external file.
If you have any other ideas please let me know...
