Proposed new beatmap object model

[ddevault]

public class BeatmapSetInfo // db bound
{
    [PrimaryKey]
    public int BeatmapSetID { get; set; }
    [sqlite-net-extensions ormy stuff goes here]
    public BeatmapMetadata Metadata { get; set; }
    public string Hash { get; set; }
    public string Path { get; set; }
}

public class BeatmapInfo // db bound
{
    [PrimaryKey]
    public int BeatmapID { get; set; }
    [ormy stuff]
    public BeatmapMetadata Metadata { get; set; }
    [ormy stuff]
    public BaseDifficulty BaseDifficulty { get; set; }
    [ormy stuff]
    public BeatmapSetInfo BeatmapSet { get; set; }
    public string Version { get; set; }
}

public class BeatmapMetadata // db bound
{
    [PrimaryKey, AutoIncrement]
    public int ID { get; set; }

    public int BeatmapSetID { get; set; }
    public string Title { get; set; }
    public string Artist { get; set; }
    public string AudioFile { get; set; }
    public string BackgroundFile { get; set; }
    // ...
}

public class BaseDifficulty // db bound
{
    // ...
}

public class BeatmapSet
{
    public BeatmapSetInfo Info { get; set; }
    public List<Beatmap> Beatmaps { get; set; }
}

public class Beatmap
{
    public BeatmapInfo Info { get; set; }
    public List<HitObject> HitObjects { get; set; }
    // ...
}

// Usage

// Get list of beatmaps in the db (i.e. SongSelect):
var beatmapSets = BeatmapStorage.Query<BeatmapSetInfo>().Where(...) etc

// Save a beatmap to the db
BeatmapSetInfo info = ...;
BeatmapStorage.Update(info);

// Get a full beatmap object:
BeatmapSetInfo setInfo = BeatmapStorage.GetBeatmapSet(113377);
Beatmap beatmap = BeatmapStorage.GetBeatmap(setInfo.Beatmaps[0]);
