> Taxonomy was introduced as a tech preview feature earlier, but the following
> challenges in design/implementation make it necessary to replace the current
> implementation with newer features being introduced:
>
> 1. Current implementation uses tags to model taxonomy terms, which limits a
> term to be associated to one entity only. Associating with multiple entities
> would require copying of a term, making it difficult to manage.
> 2. Current implementation uses dot separated naming convention to model
> taxonomy hierarchy. This makes it inefficient to rebuild taxonomy hierarchy.
> 3. Current implementation uses tinkerpop blueprints API and makes it
> difficult for migration to newer tinkerpop version.
> 4. Current implementation is tied to tinkerpop2/titan0 version and since this
> is not abstracted; it blocks the introduction of JanusGraph into Atlas
>
> ATLAS-1410 introduces a new Glossary API, which uses entities to model
> taxonomy terms and uses relationships feature to associate terms with
> entities. Also, the new model includes categories, which makes Glossary to be
> used for wider use-cases. Use of relationships to associate terms with
> entities would also allow tag-propagation more naturally.
>
> Given above, I propose to remove current tech-preview implementation of
> taxonomy feature from both server-side and UI in master branch. Once this is
> removed, existing taxonomy terms will be seen as tags along with rest of the
> tags.
