Note that the identifier is composed in different ways for the Canonical and Deprecated URN (all other portions are the same). The identifier in the Canonical URN is composed of the unique identifier which may be scoped to the agency or the maintainable object (urn:ddi:DDIAgencyID:BaseID:Version). In the case of being scoped to the maintainable, the identification is the ID of the Maintainable parent, followed by a dot '.', followed by the ID of the object. The identifier in the Deprecated URN is composed of the following parts separated by ':' a colon: The object type of the Maintainable Object, the ID of the Maintainable Object, and if the object is Versionable or Identifable this is followed by the Object Type and the Object ID.

You must designate they type of URN supported by your agency, either "Canonical" or "Deprecated". To fully support interoperability both the DDI URN and identification sequence should be used. Note that to support interoperability of the canonical and deprecated URN. If both URN and the identification sequence is used, and there is any conflict, the URN takes precedence. The action attribute is used ONLY for inheritance is a Group structure. For the local use the maintainable you can "Add", "Delete", or "Replace" an identified object.

There are three possible values for "action": Add - A new identifiable object (an Identifiable, Versionable, or Maintainable element) is provided locally with a new identifier (one that is not inherited). All properties (elements and attributes contained in the object) of the object are as specified. If an object with an existing id is created, this is an error.; Update - An object is provided locally with the SAME id as the inherited object. For each type of property that is specified locally, a full set of those properties is specified for local use. These properties replace any properties of this type which were inherited. Unspecified properties are used as inherited.; Delete - An object is provided locally with the SAME id as the inherited object. All properties specified locally in this object will be deleted if their types and values match those inherited. Note that to completely delete an object at the local level, all properties of the inherited object must be listed.

<!-- Maintainable -->
<xs:annotation>
<xs:documentation>
Used to identify described maintainable objects for purposes of internal and/or external referencing. Elements of this type may be maintained as independent objects (outside of a parent object). Provides containers for Uniform Resource Name (URN) as well as ID information. An entity can either be identified either by a URN and/or an identification sequence. At a minimum, one or the other is required. You must designate they type of URN supported by your agency, either "Canonical" or "Deprecated". To fully support interoperability both the DDI URN and the full identification sequence should be used. Note that to support interoperability of the canonical and deprecated URN, at minimum the MaintainableIdentifier and TypeOfMaintainableObject should be supplied if the canonical URN is being used by the agency. If both URN and the identification sequence is used, and there is any conflict, the URN takes precedence. The element can be designated as an addition, replacement, or deletion to facilitate tracking changes. In addtion to the elements and attributes inherited from AbstractIdentifiable, additional information regarding the versioning process can be provided; version date, the person and/or organization within the maintenance agency responsible for the change as either text or reference, and the reason for the change. If the object created was based on an exisiting object (other than by versioning), the object on which it is based can be identified using BasedOnReference. In addition to UserID, versionable and maintainable objects may also designate additional user specific properties expressed as a key/value pair using UserAttributePair. Maintainable objects may also contain any notes related to the objects they contain, identification of the software used to create and/or manage the metadata, a statement of the metadata quality, and a default URI value to use for external external references. The attribute xml:lang can be used to provide specification of the default language of the metadata contents. When the isPublished attribute is set to "true" it indicates to the user that they may safely reference the contents as they will continue to be accessible and any changes in the non-administrative content will be tracked by a versioning mechanism.

Note allows for the attachment of a piece of additional information to any object with an ID. Note facilitates capturing temporary processing notes such as "Review and approval required". A single note can be attached to multiple objects by reference to the objects. Note may also contain content for a needed object that has been reported for addition in a later version of the schema. Ideally this should be handled by a local extension, but Note can accommodate run-time extensions when required. The Note should be housed within the Maintainable object that contains the referenced objects. In this way the user is ensured of receiving all known Note attachments when the maintainable content is delivered. This means that if a Note references objects within multiple Maintainable objects, the Note should be repeated in each Maintainable and reference only those objects with that Maintainable.

Used for referencing an identified entity expressed in DDI XML, either by a URN and/or an identification sequence. If both are supplied, the URN takes precedence. At a minimum, one or the other is required. If the identification sequence is used the content of MaintainableObject may be required to be able to assemble the canonical or deprecated DDI URN. To fully support interoperability both the DDI URN and the full identification sequence should be used. Note that to support interoperability of the canonical and deprecated URN, at minimum the MaintainableIdentifier and TypeOfMaintainableObject should be supplied if the canonical URN is being used for the reference. The lateBound attribute has a boolean value, which - if set to true - indicates that the latest version should be used. Use the attribute lateBoundRestriction to indicate when a portion, such as the major version number, should be restricted to a specific value and then late bound within that restriction. Element descriptions will contain a list of applicable TypeOfObject values.

Use when lateBound is changed to "true". The specifies the point to begin late binding the version number. For example if an object had a two part version number such as X.Y where X is a major version and Y a minor version and the request is for the latest minor version of major version number 4, the content of this field would be 4. Indicating lateBound and not providing information for this field indicates the request is for the latest version available without restriction.

A reusable type assigned to an element with the naming convention XxxName e.g. OrganizationName at selected locations where the element may be assumed to be administered by a registry or is otherwise shared. This is a human understandable name (word, phrase, or mnemonic) that reflects the ISO/IEC 11179-5 naming principles. An item administered by a registry should have at least one name. Names within an administered registry should follow the naming conventions of the registry. If more than one name is provided the context of each name should be noted and one name selected as the preferred name. See ISO/IEC 11179-5 Information Technology - Metadata Registries (MDR) Part 5: naming and identification principles. ISO/IEC1179-5:2005(E).

A structured display label for the element. Label provides display content of a fully human readable display for the identification of the element. DDI does not impose any length limitations on Label. If length of Label is constrained due to use of the element in a specific application, the maximum length supported should be noted in the attribute maxLength. TypeOfLabel should be used to indicate the application either directly or as an identified type, such as “systems with an 8 character label length limitation”. The label may also indicate its applicability to a specific locale using the attribute locationVariant. Label may be repeated to provide content for different uses or situations. Language variants should be made within the Label using the internal structure of the Structured String type. The assumption is that replication of Label is done to provide different intellectual content or content specific to differing systems or applications.

If the content is from a controlled vocabulary provide the code value, as well as a reference to the code list from which the value is taken. This differs from a CodeValue only by the provision of a language-location specification. DDI uses the International CodeValue in cases where controlled vocabularies are assumed to be highly language specific, such as nationally maintained subject headings, thesauri, or keywords derived from the content of documents. The ability to identify language is especially important when supporting searches by external language-specific search engines.

<!-- NOTES -->
<xs:annotation>
</xs:annotation>
</xs:element>
<xs:annotation>
<xs:documentation>
A note related to one or more identifiable objects. Note is designed to be an inherent part of the DDI. (Unlike XML comments or other types of system-level annotations, which may be removed during processing.) DDI recommends placing the note within the maintainable object containing the objects this note relates to in order to assist tracking of note items within a study. Each note may indicate who is responsible for the note, its type using a controlled vocabulary, the subject of the note, a head and note content, a set of key/value pairs and language specification for the overall note. In addition each note must be related to one or more identifiable objects.

The content of the note. Note should contain content except when it is a production flag that is fully explained by its "type". If the note provides system specific information in a structured way using XHTML formating, DDI strongly recommends the use of local extensions or the Key/Value pair structure in ProprietaryInfo whenever possible.
</xs:documentation>

</xs:element>
<xs:annotation>
<xs:documentation>
A set of actions related to the object as described by a set of name-value pairs. This would commonly be used in a case where additional information needs to be recorded regarding the content of a new element or attribute that has not yet been added to the schema, for example when a bug for a missing object has been filed and the user wishes to record the content prior to correction in the schema. Ideally this should be handled by local extensions of the schema as described in Part 2 of the formal documentation. However, the structure in Note allows for an unanticipated need for an extension at run time by providing a means of capturing system specific information in a structured way.

Structures the representation for a geographic point to ensure collection of relevant information using a single response domain structure. The point may be associated with a polygon (such as the centroid of the polygon) or a line (end or shape points of a line). The structure provides a description of the default values for the datum type, coordinate system used, the coordinate zone, error correction method, standard offset, the geographic object being positioned, the type of address match if used, the point format, and spatial primitive type. It provides response options for the coordinate pairs being captured, and alternate values for the offset, geo-referenced object and coordinate system if a different one is used to capture a specific response.

A value along the MeasureDimension is defined by a stack of references to one or more MeasureDefinitions found in the logical description of the NCube with each containing an attribute of orderValue which provides its value for use in the cell address (similar to the use of a CodeRepresentation of a Variable used as a conceptual dimension. This allows measures (whether one or several) to be handled in the same way as the conceptual dimension of the NCube in declaring a cell address. It is assumed that the value of the MeasureDimension is the last value in the address array. For example, for an NCube with 3 conceptual dimensions of rank 1 = Sex, rank 2 = Age, and rank 3 = Educational Attainment, plus a MeasureDimension. The cell address of 1,4,2,2 would indicate Code value of 1 for Sex, 4 for Age, 2 for Educational Attainment, and 2 for MeasureDimension. For systems translating to SDMX or an OLap structure DDI assumes that the MeasureDefinitionReference with the orderValue="1" is the equivalent of the PrimaryMeasure.
