Introduction

This documentation describes the installation, configuration and use of the Fedora Export Plugin in Goobi workflow.

Overview and functionality

An export step must be configured:

• Export DMS

• Automatic task

• Plugin for step: FedoraExport

When the step is executed, the Goobi process is exported (in the same way as it is exported to the file system) to the configured Fedora Repository, taking into account the configuration (see above).

The following process properties are used to create container URLs or additional container attributes (and are mandatory):

• barcode (containing either a 10-character barcode or a 36-character PID)

• unit_Item_code (only mandatory when using a 10-digit barcode)

• full_partial

The process data can then be retrieved from the repository using the following URL pattern:

http(s)://<Fedora REST endpoint>/records/<barcode.substring(0,4)>/<barcode.sunstring(4,8)>/<barcode.substring(8,10)>/

Integration of the plugin into the workflow

Examples of URLs after successful ingest to Fedora

Example using a barcode (barcode=“barcode123”):

Main container for the pictures

http://localhost:8888/fedora/rest/records/barc/ode1/234/images/

Container for the master images

http://localhost:8888/fedora/rest/records/barc/ode1/234/images/1/files/master_00000001.tif http://localhost:8888/fedora/rest/records/barc/ode1/234/images/2/files/master_00000002.tif http://localhost:8888/fedora/rest/records/barc/ode1/234/images/3/files/master_00000003.tif

Containers for JP2 derivatives

http://localhost:8888/fedora/rest/records/barc/ode1/234/images/1/files/00000001.jp2 http://localhost:8888/fedora/rest/records/barc/ode1/234/images/2/files/00000002.jp2 http://localhost:8888/fedora/rest/records/barc/ode1/234/images/3/files/00000003.jp2

Example using a PID (barcode=“DB0027DB-F83B-11E9-AE98-A392051B17E6”):

Main container for the pictures

http://localhost:8888/fedora/rest/records/DB/00/27/DB/-F83B-11E9-AE98-A392051B17E6 /images/

Container for the master images

http://localhost:8888/fedora/rest/records/DB/00/27/DB/-F83B-11E9-AE98-A392051B17E6 /images/1/files/master_00000001.tif http://localhost:8888/fedora/rest/records/DB/00/27/DB/-F83B-11E9-AE98-A392051B17E6/images/2/files/master_00000002.tif http://localhost:8888/fedora/rest/records/DB/00/27/DB/-F83B-11E9-AE98-A392051B17E6/images/3/files/master_00000003.tif

Containers for JP2 derivatives

http://localhost:8888/fedora/rest/records/DB/00/27/DB/-F83B-11E9-AE98-A392051B17E6/images/1/files/00000001.jp2 http://localhost:8888/fedora/rest/records/DB/00/27/DB/-F83B-11E9-AE98-A392051B17E6/images/2/files/00000002.jp2 http://localhost:8888/fedora/rest/records/DB/00/27/DB/-F83B-11E9-AE98-A392051B17E6/images/3/files/00000003.jp2

Configuration

The configuration is done via the configuration file intranda_export_fedora.xml and can be adapted during operation.

Parameter	Explanation
fedoraUrl	REST Endpoint of the Fedora application
useVersioning	If true, the versioning of Fedora is used. In this case, each time the export step is executed, a new version of the process is created in the repository. The default value is true.
userName, password	Optional Basic HTTP Authentication. Both values must be set for authentication to take place.
ingestMaster	If true is set, the master images of the operation are exported. The default value is true.
ingestMedia	If true is set, the derivatives of the transaction are exported. The default value is true.
ingestJp2	If true, the JPEG2000 images of the operation are exported to the /media subcontainer. The default value is true.
ingestPdf	If true, the PDFs of the operation are exported to the /media subcontainer. The default value is true.
ingestMetsFile	If true is set, a METS/MODS file is created and exported to the container. Default value is true.
exportMetsFile	If true is set, a METS/MODS file is created and written to the usual export folder (e.g. /hotfolder). Default value is true.
externalLinkContent	External URL using a 10-character barcode and the unit item code.
externalLinkContentPID	External URL using a 36-character PID.
fullPartialContent
availableMetadataQuery	Optional SPARQL query to add the publication date to the root container attribute of the plant. The process property available must be set for this.
imagesContainerMetadataQuery	Optional SPARQL query to add additional attributes and links to the /images container.
filesContainerMetadataQuery	Optional SPARQL query to add additional attributes and links to the /files container.
imageFileMetadataQuery	Optional SPARQL query to write additional attributes for all image files in the repository (under e.g. ../00000001.tif/fcr:metadata).

The block config is repeatable and can define different metadata in different projects. The workflow sub-element is used to check whether the current block is to be used for the current step. The system checks whether there is an entry that contains both the workflow name and the current step. If this is not the case, the block is used with <workflow>*</workflow>.
