The Application Services Library (ASL) is a public domain standard, which describes a standard for processes within Application Management (the discipline of producing and maintaining information systems and applications). The term "library" is used because the ASL standard is based on the descriptions of best practices from the industry.
This standard was developed in the late nineties in the Netherlands, originally as the proprietary R2C model, which evolved into ASL in 2000. In 2001 it was donated by the IT Service Provider PinkRoccade to the ASL Foundation, now the ASL BiSL Foundation.
ASL is closely related to ITIL, BiSL and CMM. It is described in several books and articles (most of them only available in Dutch), as well as on the official website of the ASL BiSL Foundation.
The standard was developed because of the inability to structure the way of working within the Application Management departments by only using the ITIL framework, an older library embraced by the IT infrastructure departments for structuring their way of working. At the time of development, ITIL was very useful for infrastructure management but lacked specific guidance for application design, development, maintenance and support. Newer ITIL versions, particularly V3, have increasingly addressed the Application Development and Application Management domains. A reference to a white paper comparing ITIL V3 and ASL is included.
ASL was defined in order to fill this gap for Application Management. A similar development has led to the definition of the BiSL-standard for Information Management / Functional Management.

Famous quotes containing the words application, services and/or library:
“We will not be imposed upon by this vast application of forces. We believe that most things will have to be accomplished still by the application called Industry. We are rather pleased, after all, to consider the small private, but both constant and accumulated, force which stands behind every spade in the field. This it is that makes the valleys shine, and the deserts really bloom.”
—Henry David Thoreau (1817–1862)
“Men will say that in supporting their wives, in furnishing them with houses and food and clothes, they are giving the women as much money as they could ever hope to earn by any other profession. I grant it; but between the independent wage-earner and the one who is given his keep for his services is the difference between the free-born and the chattel.”
—Elizabeth M. Gilmer (1861–1951)
“I view askance a book that remains undisturbed for a year. Oughtn’t it to have a ticket of leave? I think I may safely say no book in my library remains unopened a year at a time, except my own works and Tennyson’s.”
—Carolyn Wells (1862–1942)
