GetObjectMetadataResponse

Gets and sets the AcceptRanges.

Gets and sets the property ArchiveStatus.

The archive state of the head object.

Gets and sets the property BucketKeyEnabled.

Indicates whether the object uses an S3 Bucket Key for server-side encryption with Key Management Service (KMS) keys (SSE-KMS).

Gets and sets the property ChecksumCRC32.

The base64-encoded, 32-bit CRC-32 checksum of the object. This will only be present if it was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

Gets and sets the property ChecksumCRC32C.

The base64-encoded, 32-bit CRC-32C checksum of the object. This will only be present if it was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

Gets and sets the property ChecksumSHA1.

The base64-encoded, 160-bit SHA-1 digest of the object.

Gets and sets the property ChecksumSHA256.

The base64-encoded, 256-bit SHA-256 digest of the object.

Gets and sets the ContentRange.

Gets and sets the property DeleteMarker.

Specifies whether the object retrieved was (true) or was not (false) a Delete Marker. If false, this response header does not appear in the response.

An ETag is an opaque identifier assigned by a web server to a specific version of a resource found at a URL

Gets and sets the Expiration property. Specifies the expiration date for the object and the rule governing the expiration. Is null if expiration is not applicable.

This functionality is not supported for directory buckets.

The date and time at which the object is no longer cacheable.

The date and time at which the object is no longer cacheable.

The collection of headers for the request.

Gets and sets the property LastModified.

Date and time when the object was last modified.

The collection of meta data for the request.

Gets and sets the property MissingMeta.

This is set to the number of metadata entries not returned in x-amz-meta headers. This can happen if you create metadata using an API like SOAP that supports more flexible metadata than the REST API. For example, using SOAP, you can create metadata whose values are not legal HTTP headers.

Gets and sets the property ObjectLockLegalHoldStatus.

Specifies whether a legal hold is in effect for this object. This header is only returned if the requester has the s3:GetObjectLegalHold permission. This header is not returned if the specified version of this object has never had a legal hold applied. For more information about S3 Object Lock, see Object Lock.

Gets and sets the property ObjectLockMode.

The Object Lock mode, if any, that's in effect for this object. This header is only returned if the requester has the s3:GetObjectRetention permission. For more information about S3 Object Lock, see Object Lock.

Gets and sets the property ObjectLockRetainUntilDate.

The date and time when the Object Lock retention period expires. This header is only returned if the requester has the s3:GetObjectRetention permission.

The count of parts this object has.

Amazon S3 can return this header if your request involves a bucket that is either a source or a destination in a replication rule.

In replication, you have a source bucket on which you configure replication and destination bucket or buckets where Amazon S3 stores object replicas. When you request an object (GetObject) or object metadata (HeadObject) from these buckets, Amazon S3 will return the x-amz-replication-status header in the response as follows:

• If requesting an object from the source bucket, Amazon S3 will return the x-amz-replication-status header if the object in your request is eligible for replication.

  For example, suppose that in your replication configuration, you specify object prefix TaxDocs requesting Amazon S3 to replicate objects with key prefix TaxDocs. Any objects you upload with this key name prefix, for example TaxDocs/document1.pdf, are eligible for replication. For any object request with this key name prefix, Amazon S3 will return the x-amz-replication-status header with value PENDING, COMPLETED or FAILED indicating object replication status.

• If requesting an object from a destination bucket, Amazon S3 will return the x-amz-replication-status header with value REPLICA if the object in your request is a replica that Amazon S3 created.

• When replicating objects to multiple destination buckets the x-amz-replication-status header acts differently. The header of the source object will only return a value of COMPLETED when replication is successful to all destinations. The header will remain at value PENDING until replication has completed for all destinations. If one or more destinations fails replication the header will return FAILED.

For more information, see Replication.

If present, indicates that the requester was successfully charged for the request.

Gets and sets the RestoreExpiration property. RestoreExpiration will be set for objects that have been restored from Amazon Glacier. It indiciates for those objects how long the restored object will exist.

Gets and sets the RestoreInProgress Will be true when the object is in the process of being restored from Amazon Glacier.

The Server-side encryption algorithm to be used with the customer provided key.

For directory buckets, only server-side encryption with Amazon S3 managed keys (SSE-S3) (AES256) is supported.

If present, indicates the ID of the KMS key that was used for object encryption.

The Server-side encryption algorithm used when storing this object in S3.

The server-side encryption algorithm used when you store this object in Amazon S3 (for example, AES256, aws:kms, aws:kms:dsse).

Gets and sets the property StorageClass.

Provides storage class information of the object. Amazon S3 returns this header for all objects except for S3 Standard storage class objects.

For more information, see Storage Classes.

Gets and sets the property VersionId.

Version ID of the object.

Gets and sets the property WebsiteRedirectLocation.

If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata.
