Querying the CTAN Database with JSON – Author

The information about a single author can be obtained under the URL like


The last element in the URl is the key of the author as used by CTAN. Those keys are also listed in the list of authors.

The result is a JSON term as in the following listing:

The entry is an object. It has several attributes:

This attribute contains the key of the author. This attribute is mandatory.
This attribute contains the given name. It is optional and can be empty.
This attribute is the family name. It is optional and can be empty.

Note that the authors information does not contain the email address of the author to protect the privacy.
