Lightroom Classic: Export XMP files even if originals are not avaiable

So, I have a person that edits my files for me, but she lives in another city. So, I export the files that have to be edited in a separate catalog along with SmartPreviews. Then, I send her only the catalog, without the original RAW files (or negatives). After editing the files, she has to send me back the edits, but for that, she has to send me the whole catalog again. As there are thousands of files in the catalog, it very big, and it takes a long time to transfer the files. One solution would be to be able to export the edits in XMP files. The problem is that LR disables the export of these files as the originals are not available. It would be great to be able to export XMP files even though the original files are not present. I understand LR writes XMP files in the same folder as the originals, but it could have an option to ask where XMP files will be stored. This way, after finishing all edits, the person can just send me the XMP files which are way smaller, and then I can import these files to my original catalog and have everything ready to be exported. 

By the way, how do you do to work with remote editing? Do you send the catalog and get it back? What if you have, like, 2000 RAW files that have to be edited? How do you do it?

The solution is easy and has been around for years: DNG. The edits, a preview and a pretty large (if so set) rendered JPEG of the edits reside inside the DNG as does the dcp profile and more. No need to send a catalog or anything else; just the DNG.

Send the catalogue (with smart previews), get it back (just the lrcat), File > Import from Another Catalog.

"After editing the files, she has to send me back the edits, but for that, she has to send me the whole catalog again."

That is correct.  She needs to send you the .lrcat catalog file, but that shouldn't be terribly large and should compress down pretty well, if you zip it.

"As there are thousands of files in the catalog, it very big, and it takes a long time to transfer the files."

Not quite right.  The catalog is just one database file - the .lrcat file.  The thousands of other files you're referring to are probably the previews in the .lrdata folder(s).  She doesn't need to send you those.  All she needs to send you back is the .lrcat catalog file.  You would then need to import that .lrcat file and let Lr rebuild the previews.

I do this all the time.  The basic process looks like this - 

-Create a collection of the images you're sending off to be edited.
-Export the collection as a catalog.  In the options, only check "Build / Include Smart Previews".
-Send the folder that gets created and all its contents to the editor.
-The editor will be able to open the catalog and edit using the Smart Previews.
-When the editor is done, the only thing they need to send back is the catalog file (.lrcat file).  All the edit info is contained in that file.
-Once you get it back, go to File --> Import from Another Catalog, pick the file that was sent to you and in the options, choose "Metadata and develop settings only" in the Replace drop down.

Give it a try.  It's easy.

I don't understand how you get good results without the RAW files. Editing Smart Previews is NOT a substitute. You understand that those are rendered previews, not mosaiced RAW data?
