Subject: Friday (7/9/2012), 11:00, L120: Mark Hills on external resources
From: Vadim Zaytsev
To: SWAT

Dear colleagues,

This Friday, there will be a SEM colloquium presentation as usual.
Mark Hills will give a practice talk for his (joint with Paul Klint
and Jurgen Vinju) upcoming talk at SLE 2012, and could definitely use
feedback, so please do your best to attend. The presentation will take
place in L120 (sic!) at 11:00.
Since I am now not physically close to Amsterdam, I will try to follow
the talk and the discussion via Skype.

 Date: 7 September 2012
 Time: 11:00
 Room: L120 (CWI)
 Speaker: Mark Hills
 Title: Meta-Language Support for Type-Safe Access to External Resources
 Abstract: see below

----------------------------------------------------------------------
          Meta-Language Support
                   for
          Type-Safe Access
                   to
          External Resources

Meta-programming applications often require access to heterogeneous
sources of information, often from different technological spaces
(grammars, models, ontologies, databases), that have specialized ways
of defining their respective data schemas. Without direct language
support, obtaining typed access to this external, potentially
changing, information is a tedious and error-prone engineering task.
The Rascal meta-programming language aims to support the import and
manipulation of all of these kinds of data in a type-safe manner. The
goal is to lower the engineering effort to build new meta programs
that combine information about software in unforeseen ways. In this
talk I'll describe built-in language support, so called resources, for
incorporating external sources of data and their corresponding
data-types while maintaining type safety. I will describe the
requirements for resources, the features of Rascal that enabled us to
add them into the language, and the design of the resources extension.
I will also present several examples of existing Resources and discuss
related work.
