DSVL framework

• Present DSVLs in wider context
• Research
• Practice
• Outline framework integrating research areas
• What areas are there
• Concerns in areas
• How areas are related
• Suggest common vocabulary for workshop

6
Paper presentations

• UML Components
• A Language to Describe Software Texture in
  Abstract Design Models and Implementation, Joern
  Bettin
• Text Models
• Visual Aspect-Oriented Programming of Resource
  Constrained Real-Time Embedded Systems using the
  Port-Based Object Model of Computation, Thomas W.
  Carley, David B. Stewart
• DSVL Practice
• Experiences with Visual Programming Languages for
  End-Users and Specific Domains, Philip T. Cox,
  Trevor J. Smedley

7
Working groups

• Focus on a specific topic
• Three parallel groups
• UML Components
• Text Models
• DSVL Practice
• The goal of those groups is to
• establish theoretical background
• summarise past experience
• investigate most interesting approaches
• identify future research topics
• Groups present their results for discussion

8
Publishing results

• Poster in OOPSLA 2001
• Spreading the word
• Presented in Welcome Reception
• Visible in Exhibition Hall during conference
• Workshop web-site
• http//www.isis.vanderbilt.edu/oopsla2k1/
• Papers
• Workgroup results
• Photos ?

9
Workgroup reporting template

• Background and basic assumptions
• What has been done
• Experiences from practice
• Industry state of the art
• Collect "hot topics" in DSVLs
• What are the most interesting approaches proposed
  now (little experiences on those yet)
• Future research topics
• What should be done

10
UML ComponentsExtending existing approaches
towards DSVLs

• How powerful are UMLs extension facilities?
• Stereotypes, tagged values
• Does extending UML lose the standard value of
  UML?
• Is MOF/UML OCL a good meta-metamodel?
• How does component use differ between standard
  UML and DSVLs?
• When to use DSVL instead of standard UML?
• Architecture Framework - Metamodel

11
Text ModelsCode generation, models for text
processing

• What are the different approaches for code
  generation? pros and cons
• Model-based push, intermediate format e.g. XML,
  code-based pull
• How to address separation of concerns through
  DSVLs?
• How to divide responsibility between DSVL and
  code generator?
• Language characteristics that influence code
  generation success
• Can generated code be edited?

12
DSVL PracticeApproaches for implementing DSVLs

• How to handle metamodel evolution?
• Model code migration, size of models, number
  and distribution of users, code generation
• Organisational issues of DSVL introduction
• Models as reusable components
• How to divide responsibility between DSVL, code
  generator, and components?
• Domain characteristics that influence DSVL
  success?

Workshop topics

• Industry/academic experience reports
• Separation of concerns and the application of new
  modularity technologies to domain-specific
  languages
• Approaches to identify constructs for
  domain-specific languages
• Novel approaches for code generation from DSVLs
• Issues of support/maintenance for systems built
  with DSVLs
• Evolution of languages in accordance with domain
• Metamodeling frameworks and languages
• Tools for supporting DSVLs
• Specific domains where this technology can be
  most productive in the future
