The GAIA framework prototype, described herein, explores the possibilities and problems that arise
when combining versioning and open hypermedia paradigms. It will be argued that it - by adding
versioning as a separate service in the hypermedia architecture – is possible to build consistent
versioning of both documents and hyperstructure. This approach eases some of the problems inherent in
separating versioning of documents and structure - and even allows versioning to be added to domains
that would otherwise be unversioned. A brief introduction is given to research results in the hypermedia
versioning field and GAIA is compared with previous attempts at defining hypermedia versioning
frameworks. GAIA is capable of multi-level versioning and versioning of structures and supports
freezing mechanisms for both documents and hyperstructure. The experiences from GAIA provide an
input to new reference architectures for future versioned hypermedia frameworks.
