Getting artists by tag

[wo80]

I'm not sure this can be done with the webservice. Obviously, you could do

var artists = await Artist.SearchAsync("tag:pop");
// http://musicbrainz.org/ws/2/artist/?query=tag:pop&fmt=json

but this does not return the list as presented on https://beta.musicbrainz.org/tag/pop/artist (which seems to be sorted by some kind of 'relevance').

I get you.

All these different possibilities with Browse, search or Get is confusing.
3 different methods to get different data.
I know that it is how MusicBrainz works, i guess it's just learning curve.

For example, trying to do:
http://beta.musicbrainz.org/ws/2/release-group/a1084754-8bb5-3ebc-bbd2-6a27d48e798a?inc=ratings+releases

I wrote
var artistTracks = await ReleaseGroup.BrowseAsync("", AlbumMbid, 20, 0, "ratings","releases");
something is wrong with the query string.

[ColorTwist]

I guess after i get into it more i can assist in documentation.

[wo80]

The link corresponds to "get release-group with given MBID and include ratings+releases".

The C# code is missing the related entity (first parameter) to browse for. If it was "artist", the meaning would be "browse all release-groups that are directly linked to artist with given MBID and include ratings+releases".

i did try
await ReleaseGroup.BrowseAsync("artist", AlbumMbid, 20, 0, "ratings","releases");
but i get exception .

[wo80]

Take a look at https://wiki.musicbrainz.org/Development/XML_Web_Service/Version_2#Browse

Browsing release-groups does not support including "releases".

At the moment, the exceptions thrown when the webservice fails are not instructive at all. If you look at the response of the request, corresponding to the C# code

http://musicbrainz.org/ws/2/release-group?artist=45a663b5-b1cb-4a91-bff6-2bef7bbfdd76&limit=20&offset=0&inc=ratings+releases&fmt=json

error: "releases is not a valid inc parameter for the release-group resource."

you can see the problem. This error message should be included in the exception thrown, so:

please leave this issue open until it gets addressed :-)

[ColorTwist]

Sure,

I want to elaborate what i am trying to do and if it is possible:
First i get artist main albums:
ReleaseGroup.BrowseAsync("artist", artistMbid, limit, 0, "ratings");

I save aside the release group mbid,

Now i want to get the tracks of only one (main one preferable) of that release group, this i where i am stuck. :)

Regarding errors, just a suggestion, to show what MusicBrainz returns as error.

[wo80]

Just chain a couple of requests:

1. Browse release-groups: ReleaseGroup.BrowseAsync("artist", artist_id, ...).
2. Find mbid of release-group you are interested in (don't know what you mean by main one preferable).
3. Get details of release-group: ReleaseGroup.GetAsync(group_id, "artists", "releases").
4. Find mbid of release you are interested in.
5. Get details of release: Release.GetAsync(release_id, "recordings").

Great, will check that out.

Regarding "main one", since there are many releases per release group, i need only to feach 1 release from the group. Question is, which 1 to fetch? maybe first country that released it.

[wo80]

Yeah, I usually do something like

var release = releases.Items
    .Where(r => r.Date != null)
    .OrderBy(r => r.Date)
    .First();

That's great, i appreciate that.

Leaving this thread open until exception error:

"releases is not a valid inc parameter for the release-group resource."

is handled.
