Infrastructure

The Infrastructure Area of the OHSWG is concerned with the overall architecture of an open hypermedia system and the generic services of a hypermedia backend. More specifically, infrastructure subgroups consider what kind of architectural support and services are common to (all) open hypermedia application domains.

Common Architectural Support

The goal of the architecture subtask is to develop a general architectural framework that can capture the use of open hypermedia systems in many different application domains. Currently, the following topics have been proposed for investigation:

• open hypermedia reference architecture
• open hypermedia system interoperability
• distribution of architectural components

Common Backend Services

The goal of the services subtask is to develop a general set of domain independent services in the hypermedia backend to be used in many different application domains. Currently, the following topics have been proposed for investigation:

• atomic abstractions (i.e., types of hypermedia objects)
• scripting services
• versioning support
• access control
• transaction support
• notification control
• concurrency control

One infrastructure subgroup was formed at OHS 3.5. This subgroup covers both Architecture and Services. The future plan is to split into several smaller subgroups each focusing on a few issues.
