Hi Dannon,
I understand that instead of having one dataset with multiple files you are planning to
use existing datasets and combine them in a 'collection'. My concerns are:
1. Our data consists of 200-8000 files, can you imagine how many datasets we'll end up
with? It will be a mess.
2. All these files in a dataset belong to each other and it doesn't make much sense
to keep them separately.
3. For performance reasons, all these files are located in a single directory which makes
it easier to iterate over.
4. From my point of view, it makes perfect sense to have a concept of a
"dataset" with multiple files, you have already a dataset_xxx_files folder
anyway, and it's not a big change comparing to the new concept of
"collection"
5. We are already using the "m:xxx" type datasets (thanks John) in our project,
I guess you don't even have a timeframe for implementing the "collection"
concept? I'm sure that for many projects using multi file datasets is a requirement
now, not in 'years' time.
6. "Collection" is also a good idea and I guess they both can exist together,
but only in the future, given current users an opportunity to use Galaxy for their needs.
Otherwise we simply have to look at other frameworks which already support multi file
datasets.

Alex,
To reiterate what Jeremy has already said on the mailing list, this is definitely
something we want, and need, for Galaxy. While this particular implementation has a lot
of good parts, creating these collections as first-class composite datasets isn't
ideal and we'd be stuck supporting them going forward, forever.
There's a clear plan for implementing this in Trello (
https://trello.com/c/325AXIEr),
most of which is straightforward to implement. The 'hard' part is really going to
be implementing an ideal UI for dealing with these collections, something which we could
do in phases.
What exactly are your concerns with the implementation as set out in the Trello card?

Yeah John,
This is sad, I don't understand why it is such a problem? If it's already
implemented and used in real projects like ours - then it is needed for the community. I
don't think we have other options for our requirements, your multiple file datasets
implementation was a real saviour for us.

Hi Alex,
Thanks for the comments. The galaxy team has made it clear here and to me privately that
this will NOT be included in the Galaxy main code base. I hope and am I confident that
they will make grouping datasets work, hopefully even to thousands of files.
I do not believe the two ideas are mutually exclusive and I will be maintaining a fork
of galaxy-central with these additions, I will set this up this week hopefully. I will do
my best to respond to support requests and make multiple file datasets and composite types
in general as robust as possible, keep up with Galaxy updates, etc....
Obviously, it is risky to let a code base drift so far from galaxy main's however and
you, me, and others who might want to use them will have to carefully weigh the risks when
determining if multiple file datasets are worth the headache.
Thanks for all your help and inputs. I am sorry this did not turn out differently, I
feel I have really failed here.

Hi John,
Are you saying that "composite multiple file dataset" isn't required and
won't be implemented?
We are using your implementation of multifiles dataset ("m:xxx" type) and hope
that eventually it will be pushed into main Galaxy implementation.
As we are using Galaxy for CT reconstruction tools, where input and output can consist of
a couple thousand files, other options are not feasible, i.e. grouping datasets.

Hey Jeremy,
I am trying to think about a path forward with this composite multiple file dataset
implementation. It seems there is consensus among the galaxy team that it shouldn't be
included because grouping actual datasets would be superior. In that light, I am
revisiting this e-mail, because depending on the implementation of what you described
multiple file datasets are a specific case of this concept with some likely
uncontroversial enhancements for the specific case of composite datatypes that are a
homogeneous list of files. Does that make any sense?
If I implemented (i) and (ii) in such a way that the multiple file dataset stuff flowed
out more organically is there any chance than it could be included in galaxy-central. If
no and the implicit datatypes and parallelism stuff would remain no-gos implementing what
you described would still benefit the multiple file datasets implementation, so I still
might do this, would a clean implementation of just what you described be accepted?
Any thoughts you or anyone has on the future direction of composite datatypes in
general would be appreciated?
Thanks for your time,
-John
