freedb Extended Data

Postby gbilley » Thu Aug 04, 2016 8:35 am

Greetings,

In retrieving data from freedb, I see that extended track data is saved in the MM Song Comment field. However, if a freedb entry includes CD extended data, MM doesn't seem to retrieve and save it -- at least as far as I can find.

Does MM retrieve and save CD extended data from freedb, and if so, where does it store and display that data?

Thanks.

Can you please make few screenshots of data you are referring to?

And Do you have CDDBID for the CD that you know contains extended data on FreeDB Use http://www.freedb.org/freedb_search.php for CD search

As example http://www.freedb.org/freedb/blues/7a0a310a do not have extended data

The disc that I first noticed the problem on is b908a50f. Here's the freedb URL: http://www.freedb.org/freedb/folk/b908a50f

As you can see, the entry has both CD extended data and track extended data on several tracks. When I retrieve the data from freedb, the track data is saved in the Song Comment field.

But I can't find the CD extended data anywhere. It's not in Album or Media Comments. I've even used a SQLite browser to search in out-of-the-way places. I even tried on another computer with a fresh copy of the latest MM. Same result.

If I retrieve the data with EAC, it does pull in the CD extended data.

I'm inquiring about this for two reasons. One, obviously, is that some entries might have useful CD extended data, so it would be useful to have it brought into MM.

The other reason is that I developed an Addon to allow users to submit data to freedb from MM. Right now, it allows you to submit a new disc, or update an existing disc.

However, if MM doesn't retrieve CD extended data, it won't be a good idea to allow updates from MM since an update would wipe the existing CD extended data on freedb.

Thanks for checking into this.

Cheers,

Gary

Hi Peke,

Sorry for the late reply. I just noticed your post today.

To answer your question, there is no pattern. Extended disc data never gets carried over to MM. I cross-checked all the discs in EAC which indicated extended disc data with the same entries in MM, and MM had none of the extended disc data. The data ranged in complexity from simple one-liners to long, multi-line statements with line breaks, tabs, and extended characters. None show up in MM.

Does MM actually capture extended disc data from freedb? And if so, where does it put it? In the Album Comments field?

Thanks.

Regards,

Gary

Hi,
As pointed, I checked our code and MMW do not import extended data by latest non documented protocol but only standard CDDB/FreeDB information structure.
