Use Case:  As a DAMS user, I need to ingest a set of digital objects

What this does

Tiered Ingest allows you to group all of the files corresponding to a simple asset's datastreams (including archival files, publication files, other derivatives created outside of Islandora) as one Fedora asset with multiple datastreams so that my workflow is streamlined and related objects are stored together in one place.Solution:  We need to use a specialized batch ingest module for this because the standard Islandora Batch only allows for two files per asset, one .xml file for the MODS datastream and one other file for the OBJ datastream. Tiered Ingest allows you to group all of the files corresponding to an asset's datastreams (with the exception of RELS-EXT) into a sub-directory, with the exception of RELS-EXT) into a sub-directory.

Staging folder structure

• All of the files you are ingesting as part of one asset

...

• will be staged in one directory per asset, as a sub-directory of

...

• a batch job folder.
• Each sub-directory corresponds to one asset and must

...

• contain at least a manifest file for the

...

• key datastreams

...

• (datastreams.txt).

...

• The batch job folder can contain just one asset folder, but would still need the extra nesting

Step 2: Create datastreams.txt manifest

Subdirectories in the batch job folder MUST each contain a manifest file named datastreams.txt. The manifest file specifies the intended structure of the DAMS asset, for instance pointing to the MODS XML containing the metadata for the asset, or specifying which additional datastreams should be created from staged files.

Each line of the manifest file contains an argument-value pair in the following format:

<ARGUMENT>==<VALUE> 

Use 2 (two) equal signs to separate arguments and values.

Manifest Arguments

Refer to Anatomy of DAMS digital assets and Content models for a list of allowed/expected datastreams per content model. Consult with the DAMS Management Team for use cases not covered by the datastreams listed in this documentation.

OBJ==primaryfile.ext

# optional, if no MODS file is included, minimal metadata is automatically generated during ingest
PDF==custom.pdf
# optional
ARCHIVAL_FILE==originalversionof_primaryfile.ext
# optional, use for archival file (e.g. uncropped scan)
COMPONENT1==componentfile1.ext
COMPONENT2==componentfile2.ext
# optional, can for instance be used in cases where a primary image is stitched from multiple component images; increment for additional files in same directory
# DO NOT use for complex objects that can be modeled as paged content or Islandora component assets!

DERIVATIVE1==anyarbitraryderivativefile.ext [use for derivative file with direct descendant relationship from file designated OBJ; increment for additional in same directory]

COMPONENT1==anyarbitrarycomponentfile.ext [use for cases such as a file comprising one piece of a stitched OBJ or one page image in a pdf OBJ; increment for additional in same directory]

MEDIAPHOTOGRAPH1==anymediaphotographfile.ext [use for images documenting physical media, cases, covers, etc.; increment for additional in same directory]

MODS==metadata.xml   [use for optional included metadata file, if not included then very minimal mods will be added]

Notes:  

• [text] should not be included in datastreams.txt file, used above for explanatory purposes only.
• Additions beyond the standard datastream IDs shown above are allowed.  Consult with DAMS Management Team for recommendations. 

Example Ingest:

User1 in Architecture has a collection and needs to ingest their media with extra datastreams

they use ftp to upload their files to the server in a directory called batch1

fill out form as follows:

Select top-level UTL collection for this batch  >>> Architectural Collections

sample directory structure:

utlarch

    batch1

    set1

        datastreams.txt

primaryfile.tif

        anyarbitraryderivativefile.ext

        anyarbitrarycomponentfile.ext

        anymediaphotographfile.ext

        metadata.xml

    set2

       datastreams.txt

primaryfile.tif

        anyarbitraryderivativefile.ext

        anyarbitrarycomponentfile.ext

        anymediaphotographfile.ext

        metadata.xml

Notes:

...

audiotranscript.txt
# Textual representation of linguistic content in audio and video assets. REQUIRED for audio assets to be publishable. Transcripts MUST be in plain text.
PROXY_MP4==audioderivative.mp4
# optional; audio content can be provided as streaming media, which adds a limited technical hurdle against a simple download of a complete MP3 audio file. If you prefer to deliver audio content as streaming media, you need to externally create an MP4 derivative and ingest it into a datastream labeled PROXY_MP4.

OBJ==videofile.mpg
MODS==metadata.xml
# optional, if no MODS file is included, minimal metadata is automatically generated during ingest
CAPTIONS==videocaptions.vtt
# Timed textual representation of linguistic content in audio and video assets. REQUIRED for video assets to be publishable. Captions MUST be provided in WebVTT format.
TRANSCRIPT==audiotranscript.txt
# optional; textual representation of linguistic content in audio and video assets. Transcripts MUST be in plain text.

Step 3: Upload batch job to Jscape

Step 4: Set up collection and submit form in DAMS interface
