Wishlist: Info from .xml

[HeresJonny]

I think parts of this SACDdecoder are based on the work of Maxim Anisiutkin - would it be possible to implement reading/importing the info for an ISO from an .xml file with the same name as the .iso, like in foobar2000?

Can you briefly write what exactly is the background to using the XML?
I don't really have experience with foobar2000 myself.

Is it about getting the information about the associated ISO without having to open it?

[HeresJonny]

Background is that .iso files are usually not taggeable with metadata since they are read-only. To work around this, the author of the foobar2000 SACD plugin has developed a method to write metadata to .xml files which are associated with the corresponding .iso file.

SACD .iso images are a partial exception to the rule that .iso files normally contain no metadata since the streams/tracks within sometimes DO contain info like track and artist names. However, labels write whatever info they want to their discs and however they want, like everything in caps and so on. The .xml tagging method gives the user the opportunity to use their own tagging system. However, at this point I think only foobar2000 supports writing those tags.

Aha, OK, can you give a example xml (if available, also can you rename his content, need only his style), so I look inside foobar2000's code how does and also to use the xml for tests and confirm my code comes on right compatible design, so it works on both 😄.

Maybe also a note where it is stored on foobar2000 (if you use), seen on his code this:

        store_path = core_api::get_profile_path();
        store_path.end_with_slash();
        store_path += METABASE_CATALOG;
        store_path.end_with_slash();
        auto store_file = store_path;
        store_file.end_with_slash();
        store_file += store_id;
        store_file += ".xml";

Seems stored somewhere in app user path, but not sure.

In the add-on settings you can define where the .xml is stored. Previously the default was a dedicated folder in the user folder, now the default is next to the .iso file with the same name. A long time ago I provided some files to use for others, you can find them here for download: https://sourceforge.net/projects/sacddecoder/files/sacd_metabase/

Please note that tags reflect my personal preferences at the time and not any tagging convention.

Btw, if you want to tackle this, one of your biggest challenges will probably be to get a good separator for multivalue fields. You should probably invoke black_eagle and DaveBlake who are the most knowledgeable devs in this area.

I would also like this feature implemented! This way we could tag the music however we want with .xml files. Thanks for this great add-on!
