Implements the Versioning Indicators Extension.
A concrete implementation of VersionExtension on an Asset that extends the properties of the Asset to include properties defined in the Versioning Indicators Extension.
This class should generally not be instantiated directly. Instead, call VersionExtension.ext() on an Asset to extend it.
The properties that this extension wraps.
The extension which implements PropertiesExtension can use _get_property and _set_property to get and set values on this instance. Note that _set_properties mutates the properties directly.
A base extension that just gets and sets attributes, not links.
Used for Assets and AssetDefinitions.
Applies attributes to this extension object.
Get or sets whether this object is deprecated.
A value of True specifies that the object is deprecated with the potential to be removed. It should be transitioned out of usage as soon as possible and users should refrain from using it in new projects. A link with relation type latest-version SHOULD be added to the links and MUST refer to the resource that can be used instead.
Note
A pystac.DeprecatedWarning is issued if the deprecated property is True when deserializing a dictionary to an object. The ignore_deprecated() context manager is provided as a convenience to suppress these warnings:
>>> with ignore_deprecated(): ... deprecated_item = pystac.Item.from_dict(deprecated_item_dict)
Get and set whether this object is experimental.
Specifies that the context this field is used in (e.g. Asset or Collection) is experimental with the potential to break or be unstable.
Extends the given STAC Object with properties from the Versioning Indicators Extension.
pystac.ExtensionTypeError – If an invalid object type is passed.
Gets the schema URI associated with this extension.
Get or sets a version string of this object.
A concrete implementation of VersionExtension on a Catalog that extends the properties of the Catalog to include properties defined in the Versioning Indicators Extension.
This class should generally not be instantiated directly. Instead, call VersionExtension.ext() on an Catalog to extend it.
The properties that this extension wraps.
The extension which implements PropertiesExtension can use _get_property and _set_property to get and set values on this instance. Note that _set_properties mutates the properties directly.
A concrete implementation of VersionExtension on a Collection that extends the properties of the Collection to include properties defined in the Versioning Indicators Extension.
This class should generally not be instantiated directly. Instead, call VersionExtension.ext() on an Collection to extend it.
The properties that this extension wraps.
The extension which implements PropertiesExtension can use _get_property and _set_property to get and set values on this instance. Note that _set_properties mutates the properties directly.

A concrete implementation of VersionExtension on an Item that extends the properties of the Item to include properties defined in the Versioning Indicators Extension.
This class should generally not be instantiated directly. Instead, call VersionExtension.ext() on an Item to extend it.

Generalized version of Catalog, Collection, Item, Asset or ItemAssetDefinition
alias of TypeVar(‘T’, ~pystac.catalog.Catalog, ~pystac.collection.Collection, ~pystac.item.Item, ~pystac.asset.Asset, ~pystac.item_assets.ItemAssetDefinition)
Generalized version of Catalog, Collection, or Item
alias of TypeVar(‘U’, ~pystac.catalog.Catalog, ~pystac.collection.Collection, ~pystac.item.Item)
An abstract class that can be used to extend the properties of an Item, Collection, or Catalog with properties from the Versioning Indicators Extension. This class is generic over the type of STAC Object to be extended.
To create a concrete instance of VersionExtension, use the VersionExtension.ext() method. For example:
>>> item: pystac.Item = ... >>> version_ext = VersionExtension.ext(item)
Applies version extension properties to the extended Item or Collection.
version – The version string for the item.
deprecated – Optional flag set to True if an Item is deprecated with the potential to be removed. Defaults to False if not present.
latest – Item representing the latest (e.g., current) version.
predecessor – Item representing the resource containing the predecessor version in the version history.
successor – Item representing the resource containing the successor version in the version history.
Extends the given STAC Object with properties from the Versioning Indicators Extension.
This extension can be applied to instances of Item or Collection.
pystac.ExtensionTypeError – If an invalid object type is passed.
A list of rel types defined in the Version Extension.
See the Version Extension Relation types documentation for details.
This link points to a version history or changelog.
This can be for example a Markdown file with the corresponding media type or a STAC Catalog or Collection.
Indicates a link pointing to a resource containing the latest version.
Indicates a link pointing to a resource containing the predecessor version in the version history.
Indicates a link pointing to a resource containing the successor version in the version history.
Context manager for suppressing the pystac.DeprecatedWarning when creating a deprecated Item or Collection from a dictionary.
