Request: Facilitate visualization of qza/qzv artifacts

[jennaj]

Currently, the "transfer by URL" fails over at https://view.qiime2.org for known reasons per @mvdbeek.

But @bernt-matthias thinks we can maybe configure a .loc file to make hosting by URL possible.

This ticket is to track the end-user hurdle, and a potential solution.

The operation otherwise requires a Galaxy dataset download, then upload to the https://view.qiime2.org site. Exploring data there is recommended by the Qiime2 authors the primary method an end-user can use to visually inspect/explore what is actually inside of a qiime2 artifact/viz.

Other ideas: could the function of the https://view.qiime2.org website be bundled as a Galaxy tool? Could that be accessed by clicking on the eye icon, similar to how a peek view for compressed BAMs are displayed as a SAM? Or maybe better, as a dedicated Visualize tool?

Qiime artifacts are a data structure with some metadata (qzv) plus a list of content similar to a collection (qza) ... and are somewhat opaque in Galaxy. Enabling some kind of viz would be a start for making the usage easier.

@jennaj Thanks for opening this, sorry I didn't respond in chat! Shouldn't be a tool, but a galaxy viz. I looked into this before but never pushed it over the finish line -- let me see where that was.

For a workaround there is a tool since a while. Even if a viz would be better a tool seems useful for workflows / automatization.

Regarding the viz I remember that the problem was that the qzv (zip) files contain the Javascript, but it would be better if it would be a proper package, or @dannon?

We don't have the data table required by the q2view display application. You mentioned that this works on your server, so you must have that elusive data table somewhere. It would be amazing if we can find that data table (q2view_display)

No! Since my Galaxy is not public the display application never worked for me (like many others).
