Unfortunately I was unable to make the discussion call. Can you elaborate
on "ranger integration being important". I would certainly agree, but
intrigued as to whether you noted any particular points. Or was it more
recognition that we do need to think about this?  At the last meeting it
was felt a new Jira should be opened to capture any improvements to ranger
integration?

Subject: Meeting on 25th of April about relationships design

Hello,
I thought I would share details of some very productive meetings I attended
about Atlas relationships.

On the 25th of April,
We discussed the Jira 1690
https://issues.apache.org/jira/browse/ATLAS-1690 on relationships. I think
this Jira is an enabler for a lot of capability including a new glossary
https://issues.apache.org/jira/browse/ATLAS-1410.
  The meeting attendees included committers and a PMC member (Madhan)

I walked through the relationships design. We had a vibrant discussion
around the approach to take. We are thinking that in addition to a
technical document, it would be useful to story board how this would effect
users, taking into a account user interfaces. We are looking to pursue both
these approaches. On the technical front, I think more examples of how
these relationships would look in metadata , instance level and in the
graph would be helpful.

For these story board - higher level stories, there are projects detailing
proposals how metadata can/should be used by many different governance
roles. These projects are proposals for inclusion in Atlas. Various
companies have contributed to the thinking around these projects; I would
like to explicitly invite the community to feedback/ contribute to these
projects. The projects are being documented in the newly opened up Atlas
wiki :  https://cwiki.apache.org/confluence/display/ATLAS/Atlas+Projects

On the 2nd of May
  The meeting attendees included committers and  PMC members (Suma and
Madhan)

<madhan@apache.org>, eostic@us.ibm.com

We reviewed the v1.5 design document for Jira 1690. Madhan suggested the
attribute names of the end points were held in the relationship object and
not in the the typedefs, we all felt this simplified the model. We agreed
not use structures in the relationship as they require a separate vertex;
instead we would allow simple attributes. We talked of the relationship
being a vertex to cut down the number of edges especially for many to many
relationships. We agreed to add cardinality to the end points. We agreed to
remove iscontainer from the relationshipdef endpoint and have a
containerendpoint in the relationshipDef. We agreed there was enough
consensus to start coding. We agreed that we would look at the search use
cases then move onto the glossary. We talked about Ranger integration being
important.

I look forward to hearing your thoughts,ideas and responses,     all the
best, David.
