How MinimServer Deals with Tags - muzz77 - 24-03-2016 06:47
Hi Simon,
Just a question for when you have some time ... it's just a general query as I am having a robust discussion with a hardware maker regarding their app and their lack of support for Vorbis Comments. You don't need to get into intricacies of MinimServer or supply any programming that maybe commercial in confidence but as you're extremely knowledgeable on this and given that Minimserver handles all file formats well I thought you might be the best person to ask.
On reading the Minimserver documentation it appears you are mapping ID3 tags up to a Vorbis Comment tag. Presumably your programming then deals with the Vorbis Comment and any database fields and indexes are based on the Vorbis Comment name. The program then uses the functionality of Vorbis Comments like allowing multiple tags and extended field lengths. Is this a very simplistic idea of what's going on?
Also is there any other documentation you use other than that on xiph.org to explain standards in Vorbis Comment tagging?
Any comments you have would be much appreciated. BTW it's been 18months with Minimserver. I finally gave up and got a Samsung tablet and BubbleUpnp and couldn't be happier. Thanks for the recommendation.
Cheers, Kel

MinimServer maps ID3v2 tags and Apple iTunes tags to Vorbis comments using the mappings listed in this section. The mapping doesn't add any functionality, so it is only possible to support multiple tags and extended field lengths if these are present in the original file tags. Also, MinimServer maps user-defined tag names "as is" from ID3v2 (the TXXX frame) and iTunes (the '----' atom) to Vorbis comments.

There are no official standards for tag names and tag mappings. The comment names in xiph.org are a starting point but are by no means complete. I did a lot of research to find out what tag names and tag name mappings most servers and tagging programs are using. The tag mappings table used by MinimServer represents my best effort at some kind of de facto industry consensus that should produce the expected result in most cases. In addition, MinimServer supports the aliasTags mechanism to alow the default mappings to be changed if the user wants to do this.
