PAD(R) - Provided by the Association of Software Professionals

PAD(R) is the Portable Application Description, and it helps authors provide product descriptions and specifications to online sources in a standard way, using a standard data format that will allow webmasters and software application librarians to automate app listings. PAD provides a complete content solution for application developers and the webmasters of software catalogs and directories.

PAD Specification History

IMPORTANT: On December 1, 2012, the ASP has released PAD Specification v4.0. This new specification immediately replaces PAD v3.1 and prior versions. All application developers, software publishers and websites who are currently deploying and supporting the PAD 3x specification need to immediately upgrade to PAD v4.0. All are encouraged to contact the ASP's PAD Committee here: http://appvisor.com/contact/.

PAD Extensions Specification 2 (October 2004)

  • Separated into extension creation spec and extension generation tools implementation spec.
  • Applies the proven concept of field validation against regular expressions to the extensions.
  • Adds the version and home URL of the extension to the file, so it can be found and updated easily.
  • Adds the possibility to mark an extension as company information specific, so generation tools may save the data entered with the company information and it does not need to be reentered for every program.
  • Enforces reservation of extension names ("extension identifiers") to avoid naming collisions.
  • Includes the possibility to let the ASP host an extension together with a XML view of the extensions directory.
  • 100% backwards compatible

PAD Specification 2.01 (May 2004)

  • PAD 2.01 Specification
  • The PAD 2.01 Specification is now an XML file. For each field in the PAD dataset, it lists the XML tag name, the XPath, a human readable title and description, a regular expression defining a constraint for the field content, and a human readable description of the regular expression.
  • All field titles and descriptions have been reworded for better consistence, readability and clearness.
  • The regular expressions have been revised for better compatibility with different regex implementations, but without effecting their meaning.
  • Some bugs have been found and fixed in the regular expressions.
  • Some minor changes have been made to a number of regular expressions.
  • In addition to the changes noted below, nearly all field descriptions have been reworded for better language consistence, readability and clearness. Additional comments have been added to display meaningful error messages within validations.
  • Another change has been made to most of the regular expressions. Instead of using non-greedy quantifiers, which is a unique feature of PCRE (Perl Compatible Regular Expressions), we do now use the (...){min, max} syntax where needed. This makes the spec more compatible to other common regex implementations that do not support the whole PCRE syntax, but technically results in the same in our case. There have also been other fixes of small bugs in the regular expressions.
