MangoObject.identifier

[mcdittmar]

I don’t understand the purpose of this attribute from the description

• it is a required string in a MangoObject, but has no example or detail of purpose.
• the architecture diagram includes an ‘Identifier’ block in the ‘finding’ section near registry.. is this related?
• is this related to Section 2.1.1 GAIA: detection identifier?
• why isn’t this a Property of the MangoObject?

Note:

• the MangoObject.xml file has 2 MangoObject instances, the value of the identifier in each is “”, yet section 4.10.1 describes it as a ‘Unique identifier of the MangoObject’.
• the TAP implementation file maps this to a "IAUNAME" column, described as a "unique SRCID"
  I get the impression that the use case which requires this is not part of the implementations

• It relates to 2.1.1 GAIA least.
• It is a property of MangoObject

The xml files are snippet generated to help implementers.

• They are meant to be completed by the users
• The snippet generator insert into each collection a dummy item instance. This is why there there are 2 MangoObject in this snippet, one is the associated instance of the other.

IAUNAME is a perfect identifier as defined by MANGO. I do not what the trouble with this.
