, tagging also has its own problems. One of them is losing the grasp of the entire set of tags when the number of tags is growing. Piggydb offers hierarchical tagging to tackle this problem.
Hierarchical tagging allows you to classify a tag through other tags, exactly like knowledge fragments, and the classification is transitive; that is, if there is a tag “cat” classified with a tag “animal” and you classify some fragments with “cat”, then those fragment will be classified as an “animal” also. The hierarchical tagging feature allows you to classify fragments more naturally, and drill down a large number of fragments more easily and smoothly.
Hierarchical tagging solves this problem by allowing users to organize tags themselves in simple hierarchies.
Examples below illustrate the benefits and typical uses of hierarchical tags. As is the convention at www.threetags.com, tags are separated by semicolons; sub-tags are separated from parent tags by colons.
rst of all, please use our new service AES.io (https://aes.io), as it is much more secure than ThreeTags, and we no longer actively work on ThreeTags.
Secondly, this is how you create hierarchical software/winamp tags (in AES.io):
1. create “software” tag (left panel – click “Tags”, click “+”), type “software”, click “OK”
2. select “software” tag, click “+”, type “winamp”, click “OK”.
