Parent element supporting the unique identification of the
Transfer Object Type Descriptor within the Producer-Archive
Project.
Identifier of the Transfer Object Type Descriptor Model
upon which this Descriptor is based. It may be the
Descriptor Model as given in the standard or it may be a
specialized version. It shall be unique across the
Producer-Archive Project and shall be provided by the
Archive. The standard value for this ID, when no
specialization has been employed, is 'CCSD0014'. When
specialization has been employed, the value for the
Descriptor Model ID should be agreed between the Producer
and the Archive.
Identifier of the version of the Descriptor Model. This
allows tracking updates to the identified Descriptor
Model. The standard value for this ID, when the Descriptor
Model ID is 'CCSD0014' and no revisions to this standard
model have occurred, is 'V1.0'. When specialization has
been employed, the value for the Descriptor Model Version
shall be agreed between the Producer and the Archive.
Identifier of this Descriptor within the Producer-Archive
Project. Uniqueness shall be checked by the Archive. This
identifier can be used by a relationship element to refer
to this Transfer Object Type.
Identifier of the Producer Source sufficient to enable the
Archive to identify the origin of the SIP and to send an
acknowledgement. There may be multiple Producer Sources
sending SIPs to the Archive within a given
Producer-Archive Project. The form of the Producer Source
ID needs agreement between Producer and Archive. If
specified, only those Producer Sources identified here may
include Transfer Objects, of this Transfer Object Type, in
SIPs.
Allows a conforming XML document to have any additional
XML elements at this point in its structure.
Parent element giving a high level description of the Transfer
Object Type.
Extensive descriptive phrase used as the name of the
Transfer Object Type.
Explanatory text describing the meaning of the Transfer
Object Type.
Number of Transfer Object Type instances (Transfer
Objects) of this Transfer Object Type within the Producer-Archive Project. This may be
expressed as one, or more, or as a range of values. This
number may not be known at the time of descriptor
creation. In the case of a unique value, minOccurrence =
maxOccurrence = value.
Characterization of the size range for Transfer Objects of
this type. The size range may not be known at the time of
descriptor creation and therefore the corresponding
element may be omitted.
Specification from the Producer describing how to
recognize and/or create the preservable name to be given
to each Data Object. It shall apply to all the Data
Objects under this Transfer Object Type. It may assist the
Producer in creating the SIPs and it may assist the
Archive in preserving appropriate information.
Allows a conforming XML document to have any additional
XML elements at this point in its structure.
Parent element that identifies the collection to which the
Transfer Object Types under this Descriptor are a part, and
optionally that specify directional relationships between these
Transfer Object Types and other Data Object Types, Transfer Object Types,
Transfer Object Group Types and collections. These relationships are
specified using identifiers as given within the Descriptors of
the MOT.
Identifier of a Collection Descriptor that provides an
aggregation view that includes this Transfer Object Type.
The highest level Descriptor in the MOT shall be a
Collection Descriptor.
Parent element used to describe a relationship from this Transfer Object Type under this Descriptor to the object type or collection having the identifier given by the TargetID element (targeted object types include Transfer Object Type, Transfer Object Group Type, and Data Object Type). These are transversal links specifying the type of relation.
Allows a conforming XML document to have any additional
XML elements at this point in its structure.
Parent element that identifies one or several Group Types. A
Group Type is a set of characteristics describing zero or more
Data Object Types, even complex Data Objects Types made up of
several parts. The Transfer Object Group Type may contain
additional Transfer Object Group Types in support of complex
structures such as directory structures.
Allows a conforming XML document to have any additional XML
elements at this point in its structure.
Identifier of the Data Object Type. It shall be unique across the
Producer-Archive Project. Uniqueness shall be checked by the
Archive. This identifier can be used by a relationship element to
refer to this Data Object Type.
Explanatory text describing the meaning of this Data Object Type.
Parent element supporting the number of instances
(Data Objects) of this Data Object Type in each instance of its containing group. This may be expressed as
one, or more, or as a range of values. This number may not be
known at the time of descriptor creation and instantiation. In the
case of a unique value, then minOccurrence = maxOccurrence =
value.
Parent element supporting the number of file instances in each
Data Object Type instance. This may be expressed as one, or
more, or as a range of values. This number may not be known at
the time of descriptor creation and instantiation. In the case
of a unique value, then minOccurrence = maxOccurrence = value.
The absence of this element implies there shall be one file
instance.
Parent element supporting the identification of the format of this
Data Object Type in the Transfer Object Group Type using a MIME
type or a registration mechanism.
MIME type for the Data Object Type (e.g.,
"application/octet-stream" MIME type as documented by the
Internet Engineering Task Force (IETF)).
Parent element supporting information used to identify the
format of this Data Object Type as registered with a
specified registration authority.
Identifier of the organization or system that has
registered and holds the format description
(e.g.,IETF, CCSDS Control Authority(CA)).
Identifier of the format description within the
context of the registration authority (e.g., NSSD0145
under CCSDS CA).
Characterization of how a Data Object has been encoded. May be
used to describe possible nested encodings, for example a Data
Object encoded in a zip file and then encoded in a binhex file.
Parent element supporting the description of a relationship from this Data Object Type to the object type or collection having the identifier given by the targetID element (targeted object types include Data Object Type, Transfer Object Type, and Transfer Object Group Type). These are transversal
links specifying the type of relation.
Allows a conforming XML document to have any additional XML
elements at this point in its structure.
Identifier of a Transfer Object Group Type that shall be used to
distinguish this Group Type from other Group Types. It shall be
unique within a given Producer-Archive Project. Uniqueness shall be
checked by the Archive. This identifier may be used by a
relationship element to refer to this Transfer Object Group Type.
Explanatory text describing the meaning of this Transfer Object
Group Type.
A name for the type of Transfer Object Group Type, such as
directory, set, sequence, undescribed, or other name not included
in this list.
Characterisation of how groups of this type are encoded. It may be
used iteratively to describe possible nested encodings and in
which case they are described in the order of application. The
result of encoding shall be a single Data Object. The possible
presence of Data Object Type and any additional Transfer Object
Group Type specifications under this Transfer Object Group Type
specification shall be understood to comprise a detailed model of this
group after the encoding has been reversed. Validation of the
encoded content may not be possible because the resulting data
structure will not carry any of the identifiers associated with
the detailed modeling of this group.
Parent element supporting the number of instances (Transfer Object Groups) of this Transfer Object Group Type in each instance of its containing group or, if there is no containing group, in each containing Transfer Object Type instance. This may be expressed as one, or more, or as a range of values. This number
may not be known at the time of descriptor creation. In the case
of a unique value, then minOccurrence = maxOccurrence = value.
Parent element used to describe a relationship from this Transfer Object Group Type to the object type or collection having the identifier given by the targetID element (targeted object types include Transfer Object Type, Transfer Object Group Type, and Data Object Type). These are
transversal links specifying the type of relation.
Parent element supporting a description of the Data Object Type. A
Data Object Type describes one or more Data Objects (instances).
There may be multiple Data Object Types within a Transfer Object
Group Type.
Allows a conforming XML document to have any additional XML
elements at this point in its structure.
A name for the type of encoding, such as zip, tar, or other name
not included in this list.
Description or reference to the type of the encoding.
