Hi Ernie,
Sometime last year, I had put up a small doc trying to understand the
Lineage support in Atlas.
See if this helps.
Thanks

The APIs in question are
atlas/api/lineage/hive/table/{tableName}/inputs/graph and
atlas/api/lineage/hive/table/{tableName}/outputs/graph. The implementation
for the same is HiveLineageResource.java. (The ‘Hive’ in the names is an
unfortunate legacy – it applies to any type in Atlas that extends from a
DataSet). The UI code that shows the lineage graphs (in the older dashboard
module) should probably help see how the outputs of the two APIs can be
used for getting a lineage graph in place.
Thanks
Hemanth

Hi...
New to the list, so may have missed a response to the original note below,
but in the meantime, also had this question relative to the REST API. It
doesn't appear that there is currently a published API for declaring
lineage? (for connecting assets together). Is it just not yet documented?
Are there plans for exposing lineage definition via REST?
Thank you.

Subject: Question about REST payloads...
________________________________
Hello...
Thanks to everyone for all the useful information on the Apache Atlas site
to-date. Recently I started experimenting with Atlas, using the REST API,
and establishing some of my own types and then reviewing their metadata. I
was able to get things working for the currently published REST calls, but
would like to know more about the formatting of the payloads. The returned
JSON payload is valid but embeds further JSON that "appears" to have
additional formatting --- is this something that is handled automatically
by some of the (presumably java) existing client tooling? ...or maybe I
should have passed another argument or made a different call that would
pass back a straight text response?
Here is a snippet of the sample response I received....
{"requestId":"qtp430472391-17 -
12f1518c-fdac-4a50-a23a-f56af47ee069","GUID":"1731e6e8-ee11-4fc0-b86a-e83f08d67981","definition":"{\n
\"jsonClass\":\"org.apache.atlas.typesystem.json.InstanceSerialization
$_Reference\",\n \"id\":{\n \"jsonClass
\":\"org.apache.atlas.typesystem.json.InstanceSerialization$_Id\",\n \"id
\":\"1731e6e8-ee11-4fc0-b86a-e83f08d67981\"....
Is there a historical reason for the further formatting of "definition"? Is
there a parameter I should be passing that I accidentally missed (that
would avoid this formatting)?
Thanks. Many of our customers are considering using REST calls from a
variety of tools and languages. This structure will require additional
parsing and formatting after breaking out the initial elements.
