Metadata insert, update and delete services¶

These services provide insert, update and delete operations for metadata records. They could be used by a metadata editing program external to GeoNetwork.

This is the Create, Update, Delete part of the metadata CRUD operations in GeoNetwork. For read/retrieve operations (the R in CRUD) see Search and Retrieve Metadata services.

Insert metadata (xml.metadata.insert)¶

The xml.metadata.insert service allows you to insert a new record into the catalogue.

Requires authentication: Yes

Request¶

Parameters:

data: (mandatory) Contains the metadata record
group (mandatory): Owner group identifier for metadata
isTemplate: indicates if the metadata content is a new template or not. Default value: “n”
title: Metadata title. Only required if isTemplate = “y”
category (mandatory): Metadata category. Use “_none_” value to don’t assign any category
styleSheet (mandatory): Stylesheet name to transform the metadata before inserting in the catalog. Use “_none_” if you don’t have a stylesheet to apply
validate: Indicates if the metadata should be validated before inserting in the catalog. Values: on, off (default)

Insert metadata request example:

Url:
http://localhost:8080/geonetwork/srv/en/metadata.insert

Mime-type:
application/xml

Post request:
<?xml version="1.0" encoding="UTF-8"?>
<request>
  <group>2</group>
  <category>_none_</category>
  <styleSheet>_none_</styleSheet>
  <data><![CDATA[
    <gmd:MD_Metadata xmlns:gmd="http://www.isotc211.org/2005/gmd"

       </gmd:DQ_DataQuality>
      </gmd:dataQualityInfo>
    </gmd:MD_Metadata>]]>
  </data>
</request>

Response¶

If request is executed successfully HTTP 200 status code is returned along with an XML document with id details of the record inserted. Example success response:

<response>
  <id>31</id>
  <uuid>9c623013-8d90-4e61-ae61-8e96800f3b08</uuid>
</response>

If request fails an HTTP status code 500 is returned and the response contains an XML document with the exception. Example error response:

<error id="error">
  <message>Unique index or primary key violation: "CONSTRAINT_INDEX_1 ON PUBLIC.METADATA(UUID)"; SQL statement: INSERT INTO Metadata (id, schemaId, data, createDate, changeDate, source, uuid, is Template, isHarvested, root, owner, doctype, groupOwner) VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) [23001-152]</message>
  <class>JdbcSQLException</class>
  <stack>..</stack>
  <request>...</request>
</error>

See Exception handling for more details.

If validate parameter is set to “on” and the provided metadata is not valid with respect to the XSD and schematrons in use for the metadata schema then an exception report is returned.

Example validation metadata report:

Errors¶

Service not allowed (error id: service-not-allowed), when the user is not authenticated or their profile has no rights to execute the service. Returns 500 HTTP code
Missing parameter (error id: missing-parameter), when mandatory parameters are not provided. Returns 500 HTTP code
bad-parameter XXXX, when a mandatory parameter is empty. Returns 500 HTTP code
ERROR: duplicate key violates unique constraint “metadata_uuid_key”, if another metadata record in catalog has the same uuid of the metadata record being inserted. Returns 500 HTTP code

Update metadata (xml.metadata.update)¶

The xml.metadata.update service allows you to update a metadata record in the catalog.

Requires authentication: Yes

Request¶

Parameters:

id or uuid: (mandatory) Identifier of the metadata to update
version: (mandatory) This parameter is used by the GeoNetwork editor to avoid concurrent updates to the same metadata record. This is not accessible to the service user at present so this parameter can be set to any integer value.
isTemplate: indicates if the metadata content is a new template or not. Default value: “n”
showValidationErrors: Indicates if the metadata should be validated before updating in the catalog.
minor: If the metadata update is a minor change (changedate will not be updated, notification of change in metadata will not be sent) then this parameter should be set to “true”, “false” otherwise.
title: Metadata title (for templates)
data (mandatory) Contains the metadata record.

Update metadata request example:

Url:
http://localhost:8080/geonetwork/srv/eng/xml.metadata.update

Mime-type:
application/xml

  <minor>false</minor>
</response>

If request fails an HTTP status code 500 (server error) is returned and the response is an XML document with the exception. Example error response:

<error id="bad-parameter">
  <message>id</message>
  <class>BadParameterEx</class>
  <stack>...</stack>
  <request>...</request>
</error>

See Exception handling for more details.

  <id>10</id>
</request>

Response¶

If request executed successfully HTTP 200 status code is returned and an XML document with details of what has been deleted. Example success response:

<response>
  <id>32</id>
</response>

If request fails an HTTP 500 status code error is returned and the response is an XML document with the exception. Example error response:

<error id="metadata-not-found">
  <message>Metadata not found</message>
  <class>MetadataNotFoundEx</class>
  <stack>...</stack>
  <request>...</request>

See Exception handling for more details.

Errors¶

Service not allowed (error id: service-not-allowed), when the user is not authenticated or their profile has no rights to execute the service. Returns 500 HTTP code
Metadata not found (error id: metadata-not-found), if the identifier provided did not correspond to an existing metadata record. Returns 500 HTTP code
Operation not allowed (error id: operation-not-allowed), when the user is not authorized to edit the metadata. To edit a metadata one of the following must be true:
- The user is the metadata owner
- The user is an Administrator
- The user has edit rights over the metadata
- The user is a Reviewer and/or UserAdmin and the metadata groupOwner is one of his groups
Returns 500 HTTP code.

Batch Delete (xml.metadata.batch.delete)¶

The xml.metadata.batch.delete service deletes the metadata records in the selected set.

Note

This service requires a previous call to the xml.metadata.select service (see Select metadata records (xml.metadata.select)) to select the metadata records to delete.

Note

Only those metadata records for which the user running the service has ownership rights on will be deleted. If metadata versioning is on then deletions will be recorded in the version history.

Requires authentication: Yes

Request¶

Parameters: None

Example request:

POST:

Url:
http://localhost:8080/geonetwork/srv/eng/xml.metadata.batch.delete

Mime-type:
application/xml

Post request:
<?xml version="1.0" encoding="UTF-8"?>
<request/>

GET:

Url:
http://localhost:8080/geonetwork/srv/eng/xml.metadata.batch.delete

Response¶

If the request executed successfully then HTTP 200 status code is returned and an XML document with a summary of how the metadata records in the selected set have been processed. An example of such a response is shown below:

<response>
        <done>5</done>
  <notOwner>0</notOwner>
  <notFound>0</notFound>
</response>

The response fields are:

done - number of metadata records successfully deleted
notOwner - number of metadata records skipped because the user running this service did not have ownership rights
notFound - number of metadata records skipped because they were not found (may have been deleted)

If the request fails an HTTP 500 status code error is returned and the response is an XML document with the exception. An example of such a response is shown below:

<error id="service-not-allowed">
  Service not allowed
  <object>xml.metadata.batch.delete</object>
</error>

See Exception handling for more details.

Errors¶

Service not allowed (error id: service-not-allowed), when the user is not authenticated or their profile has no rights to execute the service. Returns 500 HTTP code
