Common Works Registration (CWR) Format
In this article, one of several articles about CWR, the Common Works Registration format will be covered. If you are looking for CWR-capable software, instead of explanations, you may want to have a look at DMP, a complete online solution for original publishers, or some of the Free CWR Tools. Some more advanced options will be covered throughout this article. Let’s get technical!
Underlying Format
CWR is based on EDI, a long obsolete standard for data exchange over 300bps modems from the seventies. I will not go into reasons why CISAC still insists on it, even plans to release at least two more versions. It is a fixed width text format, and here is a CWR 2.1 example created form made-up data in DMP.

Please note that CWR 2.2 is a dead-end and CWR 3.0 is not in real use yet.
Here is an example of the same data in normalized JSON, something that is quite familiar to contemporary software developers:

}The two works represented here contain only very basic data, most notably only the data about a single original publisher for a controlled writer. In reality, contemporary CWR files often also contain data about several original publishers for each work, administrators, and many sub-publishers with different society affiliations for their respective territories, data on agreements and different share splits for different territories. CWR files with over 100 lines per work are quite common these days.
But it is not the size that makes CWR complicated, nor this obsolete format, it is the complexity of validation rules, which differ from one society to the next and not all are documented. While a single CWR file should work everywhere, there are edge cases when the rules by different societies are conflicting. The tools on this site can help in the process of figuring thigs out. They are divided into the free tools, development tools and commercial services ones.
If you choose to do it the hard way, you should go to https://www.cisac.org and search the documents for CWR. The proper overview is in the next article.
