[ome-users] OMERO sub-folders

Hi Doug,

This sounds terrific. My understanding is that it could be similar to Gmail. Indeed, as far as I see it, they “fake” a folder structure simply by visualizing a tag structure slightly differently. In fact, for OMERO we could imagine having two separate systems. One creating “folders” which in fact creates some tag hierarchy, and the traditional tags which are not necessarily in a given order.

We have discovered that our users are quite demanding for such features and thus will eagerly monitor any developments in this direction.

Hopefully, one day we can contribute as well!

Best,

Hi Christophe,

Indeed this is a much desired feature! In the simplest possible terms, the reason we do not have sub-folders is because it is hard to do this well in a database especially once you consider permissions, in the filesystem, if it's above you, it is the master of you. This is not so in a database.

However, I'm encouraged to find that you have discovered OMERO.webtagging. Yes, it can be used to similar (and I believe in many ways, superior) effect than infinitely nested hierarchies. The tagsearch feature is a very simple implementation of a visualisation of the tag structure you have created. I have plans to implement a tree-like view of the tagged data, but this was stalled somewhat while I have upgraded many components of OMERO.web to support this work. I hope to return to it at the end of the year.

The idea is to display a tree-like structure that is familiar to the users, but is in fact working similar to tagsearch, refining the search results each time the user 'navigates' into a 'directory'. This functionality will come with a serious caveat, which is that it will not scale to huge amounts of data/tags because the queries will start to run very slowly because of how the tags are stored in the system. I hope to create this proof of concept to show that tags are powerful and useful with the idea that utilising new technology in OMERO in the future, (e.g. graph databases) we are able to scale this up.

Thanks,

Douglas

Dear all,

Is there a specific reasoning as to why it is not possible to create multiple sub-folders to sort images in ?

My understanding is that together with OMERO.webtagging a rather complex structure can be created where users can search for and find their images. However, traditionally, users are used to store their images in multiple sub-folders.

Perhaps somebody could elaborate a bit and thus enlighten our staff? ☺

Thanks,
