The Deliveries tool is a feature solely available to publishers, allowing you to send your publishing catalogue in some available structured formats to your collection societies or sub-publishers. The available formats are CWR, Catalogue Shipment & MLC’s DQI.

  • CWR – Common Works Registration is a standard format developed by CISAC. It is used to share metadata of music works and is accepted by most collection societies around the world.
  • Catalogue Shipment – A structured catalogue format used by Music Maestro
  • MLC’s DQI – The Data Quality Initiative by MLC allows you to reference your catalogue with the MLC database to address discrepancies and improve the quality of your data on the MLC database.

Prior to creating a CWR delivery, make sure your CWR Setup is complete on the Overview tab of your General Settings. Your Sending Party Name, Sending Party ID & Sending IPI No are mandatory to be included in your CWR files.

To create a delivery, head to the Deliveries index on the toolbar and start a new delivery by clicking the Create button at the top right of your screen. You then need to enter the following:


  • Name – give the delivery a name for your reference
  • Receiving Party – this is the collection society you are sending your catalogue to. This will make sure the CWR is picking up the correct agreement number. If you are sending to a sub-publisher, or don’t want agreement numbers to be included in your CWR, you can leave this field blank.
  • Territory – Here you specify all the Territories in which you want the society or sub-publisher to represent your copyright. You can use Territory Groups to select multiple Territories for your delivery. If you have Territory specific IP Chains set on your Work, all matching chains on that Work will be included in the CWR.
  • Delivery Partner  – choosing a delivery partner allows you to automate the delivery of the catalogue file via an FTP or email. For a detailed explanation on how to set up a Delivery Partner, we refer to our Settings Documentation. You can leave this field blank if you are not using a delivery partner (ie personally sending your catalogue file).
  • Output Format – Here you can choose your data format.
  • CWR Version – Here you can choose between Version 2.2 or Version 2.1. Which version to choose depends on which version the society or publisher on the receiving end prefers.


Next, you can filter which Works to include in the delivery. There are a number of factors which you can filter your Works on; such as when the Works were created, whether you publish them in a particular territory or whether you have already delivered them to a particular collection society before. Once clicking the Save button of your Delivery, Curve will automatically add all the works that meet your filters. You can flick through the list of Works, and choose to include or exclude specific Works or Catalogue Groups.


Once you are satisfied with the created Delivery, you can either export the CWR file, or deliver directly. Hitting the Export button on the top right of your screen will export your CWR file for you to share with your partners. Alternatively, if you have selected a Delivery Partner in the overview, a Deliver button will be present for you to send the CWR file directly via FTP. A new Delivery Partner can be set up in your Settings.


Once you have delivered your catalogue, your partner may provide you with an acknowledgement file. To import this ACK file, please head to the Acknowledgements page and hit the Create button at the top right of your screen.

  • Name – Name the Acknowledgement for your own reference
  • Source – Specify the Source from which this ACK file is coming
  • Delivery – Select the respective Delivery associated with this ACK file

The import will update the status of your works, and allows you to check if the registration of your Works was successful. The status will either say “Accepted” or “Rejected”

When accepted and provided in the acknowledgement file, Curve will automatically populate your Works with work aliases.

When rejected, an update on why the delivery of this particular Work has failed will display. You can choose to update your Work’s metadata based on the feedback provided, and redeliver the previously rejected works by exporting a new CWR file.
