The metadata attribute group includes common metadata attributes, several of which support conditional processing (filtering and flagging) or the creation of new attribute domain specializations.

props
Root attribute from which new metadata attributes can be specialized. This is a property attribute which supports conditional processing for filtering or flagging. If no value is specified, but the attribute is specified on an ancestor within a map or within the related-links section, the value will cascade from the closest ancestor.
base
A generic attribute that has no specific purpose. It is intended to act as a base for specialized attributes that have a simple value syntax like the conditional processing attributes (one or more alphanumeric values separated by whitespace), but is not itself a filtering or flagging attribute.

The props and base attributes each take a space-delimited set of values. However, when acting as a container for generalized attributes, the attribute values will be more complex; see Attribute generalization for more details.

platform
Indicates operating system and hardware. If no value is specified, but the attribute is specified on an ancestor within a map or within the related-links section, the value will cascade from the closest ancestor.
product
Contains the name of the product to which the element applies. If no value is specified, but the attribute is specified on an ancestor within a map or within the related-links section, the value will cascade from the closest ancestor.
audience
Indicates the intended audience for the element. If no value is specified, but the attribute is specified on an ancestor within a map or within the related-links section, the value will cascade from the closest ancestor.
otherprops
This attribute can be used for any other properties that might be needed to describe an audience, or to provide selection criteria for the element. Alternatively, the props attribute can be specialized to provide a new metadata attribute instead of using the general otherprops attribute. If no value is specified, but the attribute is specified on an ancestor within a map or within the related-links section, the value will cascade from the closest ancestor.

The audience, platform, product, and otherprops attributes are property attributes which support conditional processing for filtering or flagging. Each takes a space-delimited set of values, with optional groups of space-delimited properties. Although these attributes are not specialized and not specializeable, the group syntax matches that for generalized attributes in Attribute generalization.

deliveryTarget
The intended delivery target of the content, for example "html", "pdf", or "epub". This attribute is a replacement for the now deprecated print attribute.

The deliveryTarget attribute is specialized from the props attribute. It is defined in the deliveryTargetAttDomain, which is integrated into all OASIS-provided document-type shells. If this domain is not integrated into a given document-type shell, the deliveryTarget attribute will not be available.

importance
A range of values that describe an importance or priority attributed to an element. For example, in steps of a task, the attribute indicates whether a step is optional or required. This attribute is not used for DITAVAL-based filtering or flagging; applications might use the importance value to highlight elements. Allowable values are: obsolete, deprecated, optional, default, low, normal, high, recommended, required, urgent, and -dita-use-conref-target.
rev
Indicates a revision level of an element that identifies when the element was added or modified. It can be used to flag outputs when it matches a run-time parameter; it cannot be used for filtering. It is not sufficient to be used for version control. If no value is specified, but the attribute is specified on an ancestor within a map or within the related-links section, the value will cascade from the closest ancestor.
status
The modification status of the current element. Allowable values are: new, changed, deleted, unchanged, and -dita-use-conref-target.
