Collaboration in Software Engineering
In software development
Processes are increasingly becoming more collaborative, trying to engage
users in all development phases
Agile methodologies, development of Free Open Source Systems...
In Domain-Specific Language development
DSL development is usually centered on developers rather than the users
Even if a DSL is a language specific for a domain, domain experts have
very limited participation in its creation.
Why not making the development process for DSLs more collaborative?

How to get it?
What do we need?
Infrastructure to deal with the collaborations arisen when developing/evolving a
language
What do we propose?
A new DSL, called Collaboro, to represent proposals, solutions and comments
which arise among the members of a language community.
What shall we get?
With Collaboro we can:
Justify and argument about changes in Ecore models (Eclipse)
Record the discussions and apply a voting mechanism
Track changes
Traceability of design decisions

Conclusion and Future Work
What have we presented?
Collaboro, a brand new DSL which:
Allows representing change requests and solutions (and comments)
Promotes participation and tracking language changes
More work?
Support the collaborative development of concrete syntax
Enable Change by example
Complex decision algorithms
Generation of examples to control the evolution
