Fluid Topics' clustering feature allows content publishers to group publications or topics using a shared ft:clusterId metadata value.
It is possible to cluster DITA publications using one of two methods:
- Add the
ft:clusterIdmetadata in the<othermeta>element - Use DITAVAL filters.
Clustering requires:
- Documents sharing the same
ft:clusterIdmetadata key value to be able to switch between different versions of the same document. - Topics inside documents sharing the same
ft:clusterIdmetadata key value to be able to switch between different versions of the same topic. - Other common metadata keys (for example,
audience) with different values to distinguish them (for example,expertandbeginner).
