The status of "Card" is assigned when items are work in progress only (and may be incomplete).

The status of "Draft" is assigned when items are complete or near complete but it is known that further submission will be made before quality review. If a model fails to achieve Recorded status, it may be entered at "Draft" level.

To achieve Recorded status, items must have all mandatory meta-attributes completed. However, the set of mandatory meta-attributes that should be added by the submitter is reduced by four factors:

• Many ISO 14817 meta-attributes correspond to mandatory UML constructs and will be present automatically.
• Some meta-attributes are assigned by the registrar.
• Some meta-attributes are considered to cascade down from the top level of a submission to all the items within.
• The HA Data Registry has chosen non-compliance with ISO 14817, and a small number of mandatory meta-attributes are declared optional.

Models submitted for Recorded level status will have to pass a Recorded status level check. This check verifies that the following meta-attributes are added to the specified UML elements:

1. "Definition" - Every package, class, attribute and enumeration should have a "Definition". This should be the "documentation" or annotation associated with a UML element. Different UML tools implement this feature in different ways, but they all have the concept.
2. "Multiplicity" - Every association should specify multiplicity (expressed in the normal UML way)
3. "Data type" - Every attribute should have a data type (expressed in the normal UML way).

If a model fails the Recorded level status check, submitters will be supplied with a list of the UML elements that failed and the reasons why they failed.
The meta-attributes downgraded to optional in this trial are:

• "ASN.1 Name", "ASN.1 object identifier" for all elements
• "Definition" for Associations
• "Standard", "Format", "Unit of measure" and "Valid value rule" for Attributes.

The status of "qualified" is assigned when the all mandatory meta-attributes are completed and conform to quality requirements. The Steward makes the decision on quality.

The status of "preferred" is assigned when the Steward and Change Control Committee confirm that the item should be preferred for use in the ITS community.
