-----------------------------------------
Summary: Remove Catalog/Taxonomy feature from Atlas
Key: ATLAS-2216
URL: https://issues.apache.org/jira/browse/ATLAS-2216
Project: Atlas
Issue Type: Task
Components: atlas-core
Affects Versions: 1.0.0
Reporter: Sarath Subramanian
Assignee: Sarath Subramanian
Fix For: 1.0.0
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.
