Querying the CTAN Database with JSON – Author

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

http://www.ctan.org/json/2.0/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 a JSON term as in the following listing:

{"key":"knuth","givenname":"Donald E.","familyname":"Knuth"}  

The entry is an object. It 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

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.

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

Names

Names are a complicated matter. We are adopting a simplification inspired by BibTeX.

Examples:

{ id:"...", givenname:"Donald E.", familyname:"Knuth" }

Barbara Beeton

{ id:"..." familyname:"Beeton", givenname:"Barbara", female:"true" }

Johann Wolfgang von Goethe

{ id:"..." givenname:"Johann Wolfgang" von:"von" familyname:"Goethe" died:"true" }

Dr. Rainer Schöpf

{ id:"..." title:"Dr." givenname:"Rainer" familyname:"Schöpf" }

{ id:"..." title:"King" givenname:"Richard" jr:"III" died:"true" }

Wladimir Iljitsch Uljanow aka Lenin

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/json/2.0/author/knuth?ref=true

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

{"key":"knuth","givenname":"Donald E.","familyname":"Knuth","packages":["ada","cmtest","gkpmac","graphbase",…]} 

In this case an additional attribute is included.

packages
