Questions tagged [squeak]

Squeak is a modern, open-source implementation of the Smalltalk language, with a history of being very easy to port across platforms. See https://squeak.org/.

Squeak started in 1996 as a project of Alan Kay and friends at Apple. They wanted an open source Smalltalk with a view to building Smalltalk's replacement.

Among its features:

  • The Virtual Machine is written in (a subset of) Smalltalk.
  • Runs bit-identically across all its platforms.
  • Very easy to port: it runs on Linux, Macs (both old and new), Windows, iPhones, iPads, and even bare metal.

Parsing RDF in Smalltalk

Is there any example, in any Smalltalk flavour, showing how to parse a RDF file? The only package I've seen is Rikaiko with a RDFXMLReader class, but there are no references and it seems very undocummented.
