Perform a partial update to content or metadata of a document at a
caller-specified URI. This operation is equivalent to
PATCH /v1/documents.
| URL Parameters | |
|---|---|
| uri | The URI of the document whose content or metadata is being updated. Required. |
| category* |
The category of data to insert or update. Category may be specified
multiple times to insert or replace any combination of content and
metadata. Valid categories: content (default),
metadata, metadata-values,
collections, permissions,
properties, and quality.
Use metadata to update all metadata.
See the Usage notes below.
|
| database? | Perform this operation on the named content database instead of the default content database associated with the REST API instance. Using an alternative database requires the "eval-in" privilege; for details, see Security Requirements in the REST Application Developer's Guide. |
| format? |
The content type of the patch specification and any metadata in the
request body. Specifying format overrides the
Content-type header if the Content-type header does not map to a MIME
type equivalent to XML or JSON. Allowed values: xml,
json. For details, see
Controlling Input and Output Content Type in the REST Application Developer's Guide.
|
| txid? |
The transaction identifier of the multi-statement transaction in
which to service this request. Use the /transactions
service to create and manage multi-statement transactions.
|
| temporal-collection? | Specify the name of the temporal collection to which the document being updated belongs. For details, see Managing Temporal Documents in the Temporal Developer's Guide. |
| temporal-document? |
The "logical" document URI in the temporal collection specified
using the temporal-collection request parameter. For
details, see
Managing Temporal Documents in the Temporal Developer's Guide.
This parameter can only be used when the temporal-collection
parameter is also present.
|
| source-document? |
The temporal collection document URI of the document to be patched.
This must be the URI of a document in the collection specified by
the temporal-collection parameter. See the Usage Notes
for details.
|
| system-time? |
Set the system start time for the insertion or update. This time will
override the system time set by MarkLogic. Ignored if
temporal-collection is not included in the request.
|
| Request Headers | |
|---|---|
| Content-Type? | The MIME type of the data in the request body. See the Usage Notes for details. |
| If-Match? | Specifies a document version identifier that must match the current version of the target document for the update to succeed. If the current version of the document does not match, a 412 (Precondition Failed) status is returned. A value of 0 indicates the document must not already exist in the database. Ignored unless optimistic locking is enabled; for details see Using Optimistic Locking to Update Documents in the REST Application Developer's Guide. |
| X-HTTP-Method-Override |
This header signals that this request is a partial update to document
content or metadata. You must include this header and it must have
a value of PATCH.
|
Upon success, MarkLogic Server responds with 201 (Document Created) or 204 (Updated or Unchanged).
rest-writer role, or the
following privileges:
http://marklogic.com/xdmp/privileges/rest-writer
http://marklogic.com/xdmp/privileges/rest-reader
Use this form of POST /v1/documents to update a portion
of the content and/or metadata for an existing document at a
caller-supplied URI. For all other document and metadata creation and
update operations, use PUT /v1/documents or one of the
other forms of POST /v1/documents.
You can also use a PATCH request to apply a partial update. For details,
see PATCH /v1/documents. The functionality and request
body contents are the same.
To perform a partial update of content and/or metadata, specify the
document URI using the uri parameter, set the
category parameter to reflect the content and/or metadata
to be modified, and set the request header
X-HTTP-Method-Override to PATCH. The
request body must be a JSON or XML patch specification.
You can only apply partial updates of content to XML and JSON documents. You can apply partial updates of metadata to any document type.
When patching a temporal document, the uri parameter
specifies the URI of the output document. If you do not specify a
source document using source-document or
temporal-document, then uri also specifies
the URI of the input document.
Use the temporal-document parameter to identify the
temporal document collection URI. If temporal-document
is present and source-document is not present, then
temporal-document identifies the input document. If
source-document is present, then it identifies the
input document. The input document must be in the temporal
collection specified in the temporal-collection parameter.
The metadata-values category represents "metadata fields"
document metadata. For more details, see
Metadata Fields in the Administrator's Guide.
