Querying the CTAN Database with XML – Author

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

http://www.ctan.org/xml/1.3/author/knuth

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 an XML file as in the following listing:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE authors SYSTEM 'http://www.ctan.org/xml/1.3/catalogue.dtd'>
<author key="knuth" givenname="Donald E." familyname="Knuth" />  

The entry has the outer tag <author>. This tag has several attributes:

key
This attribute contains the key of the author. This attribute is mandatory.
title
This attribute is the title of the author. It is optional and can be empty. The default is empty.
givenname
This attribute contains the given name. It is optional and can be empty.
von
This attribute is the von part of the author's name. It is usually in lower case and has values like von, van, or de. It is optional and can be empty. The default is empty.
familyname
This attribute is the family name. It is optional and can be empty.
junior
This attribute is the junior part of the author's name. It is usually an addition to the name like jr., sr., or a numeral like I, II, III, IV. It is optional and can be empty. The default is empty.
pseudonym
This attribute is the alias name to protect the privacy of an author who requests it. It is optional and can be empty. The default is empty. In case this attribute is not empty the other name constituents are not shown.
female
This attribute is the boolean indicator that the author is female. It is optional and can be empty. The default is false.
died
This attribute is the indicator that the author is deceased. It is optional and can be empty. The default is empty.

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

References

You can request that more information about the authors is provided. This information is the list of packages in which the author is mentioned. This is accomplished with the parameter ref. It can be set to true as in the following example:

http://www.ctan.org/xml/author/knuth?ref=true

This results in an XML file like in the following listing;

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE author SYSTEM 'http://www.ctan.org/xml/1.3/catalogue.dtd'>
<author key="knuth" givenname="Donald E." familyname="Knuth">
  <package key="ada" />
  <package key="cmtest" />
  <package key="gkpmac" />
  <package key="graphbase" />
  …
</author  

In this case the <author> tag contains a list of inner tags for the packages. Each package is contained in the tag <package> which has the following attributes:

key
This attribute contains the key of the package. This attribute is mandatory.
