Sharing LR catalogs through Creative Cloud for team work

Bug with LR4 on OSX
I have exported an LR cat from my master catalog on the desktop. The export generated 3 files: xxx.lr.cat, Previews.db, root-pixels.db. I belong to Creative Cloud. I posted these 3 files to the cloud and invited a team member to download them. This team member also belongs to Creative Cloud. He is unable to see the previews after installing the three files on his computer and opening the LR cat. Our goal is to work on metadata for this particular catalog. Why is he unable to see the previews? It is woefully inefficient to force us to upload dngs to the cloud, build a catalog, and re-export and upload the dngs. The folder of dngs would be very large. Why can't the xmp be written into the catalog and shared through previews and the cloud?

I agree that it would be great to have cloud sharing with the catalogs, but back to the initial problem, I'd guess there's a permissions issue - perhaps the whole previews, maybe a file within the previews package.

By just explain your workflow for me? Are the original DNG's on both computers already? If so, just sending the catalog to the cloud and back down again would work.

I do not believe the inability of LR to support cloud sharing of catalogs is a permissions issue.

There is no permission issue if I give you an LR cat on a drive along with the corresponding previews. You can download the catalog and previews and work away. Many photographers take their LR cats and previews on the road. Why should it be different on the Cloud?

Bear in mind, the team member is not working ON the Creative Cloud, merely using the Cloud service as a relay vehicle, much like an ftp service. The team member must download the exported LR cat and supporting folders. Creative Cloud does not allow you to work Live on the Cloud.

Our dng folders from a single production day are too large to efficiently upload and download to the Cloud. If Adobe can not support cloud sharing of LR catalogs then why bother with Creative Cloud for this purpose? What is the competitive advantage?

My proposal is that Adobe support xmp changes of LR catalog and previews shared through the Creative Cloud. This would allow a photographer to upload an LR catalog to the Cloud for a key wording team to download the cat for metadata application. Assuming the catalog was properly set up to embed metadata changes, the meta team should be able to share the the tagged catalog to the Cloud again for another team member, such as an editor, to perform the next task.

Thanks for your interest in the topic.

The permissions issue I was referring to was in response to your question "Why is he unable to see the previews?"

I do agree that some kind of cloud sharing would be useful someday though.

That's not a bug, it's a design limitation. The catalogs must be local. It's requirement of SQLite, the database that LR uses. Maybe someday the catalogs can be on the network, but not now.

Lee,

The LR cat is ultimately local. It merely passes through the Creative Cloud as a delivery mechanism.

Here is the process: the LR catalog owner exports the LR catalog and preview folders. The LR Export as Catalog command generates the following files:
xxx.lr.cat
Previews.db
root-pixels.db

All the above files are posted to the Creative Cloud. Another Creative Cloud user is invited to share the folder.

The invited user downloads all the above items locally to their own computer. Previews will not appear in the LR cat when opened. It's not possible to embed metadata. Why? It works if I hand you a drive with the same folders on it.

Your thoughts?

It sure would be a nice feature.

My first thought is the stuff isn't being downloaded but that it's still on the cloud or located in a folder with the wrong permissions. Truly downloading them is the same as copying them from a hard drive.

Zipping might be the way to go. I've exported a catalogue with previews and uploaded the zipped folder to CC.

That's wonderful news, John. Thanks for unraveling this mystery.

I tested your zip file theory tonight and found it works, although the upload speed is probably too slow to be useful in the field.
