Migrating photos from Picasa to Synology Photostation?

Question

Google

Good day.
Faced such a problem. But first things first:
I bought a NAS Synology DS413. I have a photo archive (more than 100 gigs), faces are marked through Picasa (well, and other information). I ran Photostation on the server and I liked it for many reasons, but I had some questions:
1. How do I transfer faces from Picasa to Synology Photostation?
2. How to transfer geographical and other marks?
I searched the forums for solutions, but did not find them. I wrote to technical support, but they do not answer (more than a week has passed).

Answer 1

I had no business with Photostation, but I dealt with the export of faces from picasa.
If “embedding” data into photos is enabled in Picasa (Settings - Marks - Save in metadata), and Photostation supports the MWG Region Schema XMP extension, then faces should be transferred without any problems at all. If there is no such support, you will have to "shaman" with the conversion of regions from XMP to the format that Photostation understands (POST requests with coordinates to the script that is responsible for the marks?).
With saving data to photos disabled, you will have to deal with .picasa.ini files and their parsers. Now I won’t tell you the name, but I saw a good utility that can import data from .picasa.ini into the photos themselves, as if saving in metadata was enabled.
Either way, XMP is the perfect place to store this kind of information.
The remaining marks (coordinates, tags) are also saved, mainly in the form of XMP tags, so as not to touch the image itself. Although, I'm not sure about the tags, perhaps they are written in Exif.
