PubMan Sword

From MPDLMediaWiki

This page briefly describes the SWORD Server implementation in the PubMan solution. General Information about SWORD can be found here.

Implementation

For start the SWORD functionality is directly implemented in PubMan. In future we should have a separate SWORD service for all eSciDoc solutions.

PubMan implements 3 classes for the SWORD service:

1. PubManSwordServer - Processing of requests
2. PubManServiceDocumentServlet - Accepting requests for the Service Document (dependent on user credentials)
3. PubManDepositServlet - Accepting requests for the deposits (dependent on user credentials)

Interface

The PubMan SWORD interface is deployed within the PubMan ear, therefore one can access the above described servlets by the PubMan baseURL + the servlet path.

(Example with PubMan base url http://pubman.mpdl.mpg.de/pubman)

Service Document

   <atom:author>
      <atom:name>Friederike, Kleinfercher</atom:name>
   </atom:author>
   <atom:content src="http://pubman.mpdl.mpg.de/pubman/item/escidoc:xy"/>
   <atom:summary>item.xml ,123.pdf</atom:summary>
   <atom:title>First Sword item</atom:title>
   <atom:source>
      <atom:generator>http://pubman.mpdl.mpg.de/pubman</atom:generator>
   </atom:source>
   <atom:updated>2009-04-02T14:23:02Z</atom:updated>
   <sword:treatment>Zip archives recognised as content
      packages are opened and the individual files contained
      in them are stored. All other files are stored as
      is.</sword:treatment>
   <sword:acceptPackaging>http://purl.org/escidoc/metadata/schemas/0.1/publication</sword:acceptPackaging>
   <sword:noOp>false</sword:noOp>
 </atom:entry>

• The zip file may contain several files but must contain exactly one metadata file. All files not containing metadata are transformed to PubFiles and are added to the Publication item.
• The item is deposited to the collection: collectionIdentifier
• The validation of the item depends on the collection
• The action of deposit depends on the collection

Action Mapping

Important Information

• File visibility will be set to public
• File content category will be set to Publisher Version for all pdf files. Other files will get content category Supplementary Material.
