Bitstorage API

To add files to DOMS, three things will need to happen:

The file must be uploaded to bitstorage, and characterised
The file must be connected to a Fedora object datastream of type TypeFile
The characterisation output must be added to a Technical Metadata-stream in the object (the file and the characterisation result must match, see the data model documentation)

Uploading the file to bit storage must be done with API calls for

  uploadFile  - in: filename,URLToFile,md5 out:characterizationOutput,fileName,fileUrl,md5,pronomId,validationStatus
  approveFile - in: fileUrl,md5
  disapproveFile - in: fileUrl,md5
  spaceLeft - out: bytes

WSDL: attachment:Bitstorage.xml

Basically, you upload a file by presenting the bit storage resolvable URI, and the expected MD5 sum. The file will then be made available, and you will get a URI the file is stored on, and characteristica of the file back.

Those characteristica MUST be added in the proper places of the accompanying Fedora object.

Approve is used when the accompanying Fedora object is first sets published.

Disapprove is used if the accompanying Fedora object is marked deleted before publishing.

Examples

Adding a file and an accompanying fedora metadata object:

Make a new fedora object of type File in draft mode
Call upload on the bitstorage API
Add pronomid and characterisation to the appropriate datastreams
Set URL and MD5 on the CONTENT datastream

Publishing a file fedora object

Set fedora metadata objects to state "published"
Call approve from the bitstorage API
