9. Conventions for the About Tag > Tags for Indicating Related Objects (Linking...

It is common to want to create links between objects in Fluidinfo, and this is easy to do. For objects that have about tags, the obvious way to achieve this is simply to tag one object with the about tag for the other, using the name of the tag to indicate the nature of the relationship. For example, the musicbrainz.org user uses this mechanism to link artists and albums.

If we look at the object for the album Strange Fruit, by Billie Holiday (Figure 9-1, top), we see that it has a tag called related-artists that links this album to its artist—in this case, artist:billie holiday, the object in the middle. Similarly, if we look at the object whose about tag is simply Billie Holiday (bottom) we see a tag related-albums, linking to the more specific object for the artist, and also one to the album called Billie Holiday, having the about tag album:billie holiday (billie holiday).[32]
