    v23 v24  
    6060S3XML implements the [wiki:S3XRC/RESTfulAPI S3 RESTful API] and its [wiki:S3XRC/RESTfulAPI/URLFormat URL format] to address resources.
     62=== RESTful Methods ===
    6264The following methods are supported:
    7880  ||PUT <resource> ''with job ID''||commits the specified job to the database||
    7981  ||PUT <resource> ''with source''||analyzes the source, creates an import job and commits the job to the database||
     83=== Source Submission ===
     85There are multiple ways to submit source files:
     87==== Files on the Server ====
     89A source file in the server file system can be specified using the ''filename'' URL variable:
     91PUT http://<server>/<resource>?filename=<path>
     94Multiple files can be specified as list of comma-separated pathnames:
     96PUT http://<server>/<resource>?filename=<path>,<path>,<path>
     99==== URLs ====
     101A source file can be specified by its URL using the ''fetchurl'' URL variable:
     104PUT http://<server>/<resource>?fetchurl=<url>
     107Multiple files can be specified as list of comma-separated pathnames:
     109PUT http://<server>/<resource>?fetchurl=<url>,<url>,<url>
     112Supported URL protocols are http, ftp and file, where file is interpreted in the server file system context. URLs of different protocols can be mixed.
     114The specified URLs must be accessible either without authentication, or (if you specify credentials in the URLs) they must support unsolicited HTTP basic authentication - HTTP 403 retries are not handled by the interface. The URLs must be properly [ quoted], and must not contain commas.
     116==== Request Attachments ====
     118Source files can also be attached to a multipart-request. In this case the file extension of the source file must match the request URL file extension. Multiple files can be attached.
     120==== Multiple Sources ====
     122Where multiple sources are specified or attached, they are first converted and transformed one-by-one and then combined into a single element tree before import.
     124==== Duplicate Resolution ====
     126In the current S3 implementation, the interface does not handle duplicates within the same request. This is because the order of elements in the resulting element tree is not defined, and the last update time attribute is optional in source elements. Records must not be fractionated, but submitted in one element. Fractions of records will not be merged by the interface, and which of the fractions finally would be imported is not predictable.
     128Source elements using unique keys are automatically matched with existing records. Where matches are ambiguous (e.g. a set of keys matching multiple existing records), the import element will be rejected as invalid. For certain resources, the server may have additional duplicate finders and resolvers configured. How duplicates are handled by these resolvers, can differ from resource to resource.
     130The default behavior for duplicate resolution in standard import mode is to update the exiting records with the values from the source record. In synchronization mode, though, the default is to accept the newest data.
