Introduction

Avalon's batch ingest feature provides a method of building one or more media items at a time from uploaded content and metadata outside the user interface. A batch ingest is started by uploading an ingest package consisting of one manifest file and zero or more content files to the Avalon dropbox. For your convenience there is a demo ingest package available to download and import into test systems. Follow the instructions below to ensure a succesful batch upload.

Ingest Packages

An ingest package is the combination of content and metadata that make up a single batch.

Package Layout

The package (manifest file and associated content files) must be uploaded within the appropriate collection subdirectory of the Avalon dropbox. The package can either be at the root of the collection directory, or in any subdirectory thereof. All items included in a single ingest package will be uploaded to the same collection. The following is a very simple package that has been uploaded:

Manifest File Format

The manifest file is a spreadsheet (xls, xlsx, csv, or ods) containing the metadata for the items to be created, as well as the names of the content files that make up each item. In this case, the manifest file is named batch_manifest.xlsx. See batch_manifest_template_R3.xlsx for an Excel example file. Required fields are in bold.

4Test item 2Northwestern1951content/file_3.mp4   

Row 1, Column A contains a reference name for the batch. This is mostly for your reference so we recommend naming the batch file according to what will help you remember the contents.

Row 1, Column B contains the submitter's email address (to be used for notifications and exceptions). The submitter's email must be listed as a manager, editor, or depositor for the collection in which this batch is deposited in the Avalon dropbox.

Row 2 specifies the names of the metadata fields supplied in the following rows. Main TitleCreator, Date Issued, and File are required. These fields are shown in bold in the Excel example file. Each subsequent row represents a single media item to be created. Metadata values are specified first, followed by a list of content files to be attached to each item.

Content files listed in the manifest file must have the correct path noted for where those files are located in the Avalon dropbox, relative to the manifest file. Additionally, all content files must include a file extension. If necessary, include any directories or subdirectories (note the paths listed in columns D and F in the above example).

Multivalued fields are specified by multiple columns with the same header, e.g. Topical Subject in the following example:

Supported Field Names (required fields in bold)

In addition to the descriptive fields, there are five supported operational fields:

Notes

The batch ingest process will verify that the package is complete (i.e., all content files specified in the manifest are present and not open by any other processes) before attempting to ingest. If the package is incomplete, it will be skipped and returned to on a subsequent pass.

Each batch will generate 2 emails to the email address listed at the top of the manifest.
