http://schemas.opengeospatial.net/csw/2.0.1/CSW-publication.xsd This schema defines the request and response messages for the CSW-Publication operations specified in clause 10 of OGC-04-021. Users may insert, update, or delete catalogue entries. If the verboseResponse attribute has the value "true", then one or more csw:InsertResult elements must be included in the response. Submits one or more records to the catalogue. The representation is defined by the application profile. The handle attribute may be included to specify a local identifier for the action (it must be unique within the context of the transaction). Update statements may replace an entire record or only update part of a record: 1) To replace an existing record, include a new instance of the record; 2) To update selected properties of an existing record, include a set of RecordProperty elements. The scope of the update statement is determined by the Constraint element. The 'handle' is a local identifier for the action. Deletes one or more catalogue items that satisfy some set of conditions. The RecordProperty element is used to specify the new value of a record property in an update statement. The Name element contains the name of a property to be updated. The name may be a path expression. The Value element contains the replacement value for the named property. The response for a transaction request that was successfully completed. If the transaction failed for any reason, a service exception report indicating a TransactionFailure is returned instead. Reports the total number of catalogue items modified by a transaction request (i.e, inserted, updated, deleted). If the client did not specify a requestId, the server may assign one (a URI value). Returns a "brief" view of the catalogue items modified by some transaction. The handle attribute may reference a particular statement in the corresponding transaction request. Requests that the catalogue attempt to harvest a resource from some network location identified by the source URL. Source - a URL from which the resource is retrieved ResourceType - a URI that specifies the type of the resource (DCMES v1.1) being harvested if it is known. ResourceFormat - a media type indicating the format of the resource being harvested. The default is "application/xml". ResponseHandler - a reference to some endpoint to which the response shall be forwarded when the harvest operation has been completed HarvestInterval - an interval expressed using the ISO 8601 syntax; it specifies the interval between harvest attempts (e.g., P6M indicates an interval of six months). The content of the response varies depending on the presence of the ResponseHandler element. If present, then the catalogue should verify the request and respond immediately with an csw:Acknowledgement element in the response. The catalogue must then attempt to harvest the resource at some later time and send the response message to the location specified by the value of the ResponseHandler element using the indicated protocol (e.g. ftp, mailto, http). If the ResponseHandler element is absent, then the catalogue must attempt to harvest the resource immediately and include a TransactionResponse element in the response. In any case, if the harvest attempt is successful the response shall include summary representations of the newly created catalogue item(s).
