The digital warehouse offers you the possibility to add new publications, or to update the metadata of existing publications, in batch.

Overview of batch processing

The platform creates or modifies a batch of publications using an external file that you must prepare and import.

This external file can take two forms:

  • A metadata file, which is a single file containing the metadata of the publications to be added/modified (title, authors, etc.).
  • An import folder, which is a folder compressed into one file, and containing the above metadata file, together with any other files (EPUB, PDF, JPG) to be associated with the publications to be imported/modified.

In the metadata file, each publication is identified by its ISBN (or EAN). As this identifier is unique and permanent, it is the key that the platform examines when importing a metadata file, to determine how to process each publication it contains.

  • If the identifier does not already exist in the warehouse, a new publication is created, and the corresponding metadata in the file is applied to it.
  • If the identifier already exists in the warehouse, the metadata of the corresponding publication will be updated with that contained in the metadata file.

The processing of metadata is as follows:

  • If a data item is present in the metadata file and in the warehouse, the information in the file will replace that in the warehouse.
  • If data is present in the metadata file and not in the warehouse, the information will be added to the warehouse (if its format is recognized).
  • If data is absent from the metadata file but present in the warehouse, the data present in the warehouse will be kept intact.
  • If an ONIX 2.1 or ONIX 3.0 tag is present in the metadata file, but is empty, the corresponding data in the warehouse will be deleted. 
The steps to import a batch of publications are as follows:

  • Metadata must be in XLMS or ONIX formats.

  • When importing files, these must be placed with the metadata in a single folder and compressed in .zip format.

  • The import results can be seen in the System Tasks section.

  • No file may be above 150 Mb.

  • No archive (compressed file) may be above 500 Mb.

  • Importing can be done using the interface or FTP upload.
