The sixth European Lisp Workshop was held on July 6 in Genova, Italy, in
co-location with ECCOP 2009.
It was sponsored by ITA Software and EPITA.

Edi Weitz gave a keynote talk entitled: Lisp in the Real World[TM]. The abstract is given below:
Edi Weitz is well known in the Common Lisp community for his numerous
open source libraries. In this keynote, he will talk about some
applications of these in commercial projects he's been working on. The
focus is intended to be on Real World[TM] usage of Lisp so that the
talk hopefully turns into surreptitious advertising for the upcoming
European Common Lisp Meeting which has the same theme.

Minimal filtered dispatch
Pascal Costanza A central contribution of object-oriented programming is ad-hoc polymorphism via dynamic method dispatch, which enables behavioral variations based on typically one receiver argument in object-centric languages, or potentially multiple arguments in languages based on generic functions. In object-centric languages, methods and their overriding relationships are defined along the inheritance chains of classes or objects, but even in the case of generic functions, method selection and combination is driven by the inheritance hierarchies in which the received arguments are involved. In the presentation, I would like to give an overview of the ideas behind filtered dispatch, show some details of the minimal version, and try to sketch some ideas how to proceed further with this idea. My hope is to start some discussion with the audience how this can be used to improve the CLOS MOP, and deepen both their and my understanding of the involved issues.SWCLOS: A Semantic Web Processor on CLOS
Seiji Koide SWCLOS is a Semantic Web processor built on top of CLOS which represents vocabularies defined in RDFS and OWL as CLOS objects that obey the semantics of RDF and OWL. SWCLOS allows Lisp programmers to build ontologies in RDFS and OWL, and write diverse Semantic Web applications naturally in Common Lisp. For example, using SWCLOS programmers can internally process RDF descriptions as S-expressions and externally communicate information in the RDF/XML encodings of the Semantic Web. SWCLOS also provides the following functionality.
