Subject [jira] [Updated] (ATLAS-1410) V2 Glossary API
Date Thu, 13 Apr 2017 16:12:41 GMT

     [ https://issues.apache.org/jira/browse/ATLAS-1410?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

David Radley updated ATLAS-1410:
--------------------------------
    Attachment: Atlas Glossary V2 proposal v1.4.pdf

Added a document to remove the classification details and remove the details of the relationship.
These will be designed separately. I have added more detail around how semantic relationships
could be implemented.

> The BaseResourceDefinition uses the AttributeDefintion class from typesystem. There are
newer more funcitonal versions of this capability in the atlas-intg project. This Jira is
changing over the glossary implementation to the newer entity / type classes.  
> Instread of the instanceProperties and collectionProperties in the BaseResourceDefintions
we should use something in this sort of style :

> For the parent child relationships with glossary categories and terms we should be able
to have the type system manage edge deletion. As part of this, we will need to investigate
whether we could get rid of the disconnect and connect methods added in ATLAS-1186
