Driven by the philosophy of the ‘primacy of structure over data’, Component-Based Open Hypermedia Systems (CB-OHS) present an open set of structure servers providing structural abstractions of different hypermedia domains. To address the emergent requirements and to facilitate the development of structure servers, structure should be handled as a first(More)
The decline of bees has raised concerns regarding their conservation and the maintenance of ecosystem services they provide to bee-pollinated wild flowers and crops. Although the Mediterranean region is a hotspot for bee species richness, their status remains poorly studied. There is an urgent need for cost-effective, reliable, and unbiased sampling methods(More)
The general goal of our research is to automatically generate links and other hypermedia related services to analytical applications, such as geographic information systems and decision support systems. Using a dynamic hypermedia engine (DHE), we propose to automate the following features for database systems, both on and off the Web. First, we(More)
Behavior has only recently received the attention of structural computing research. Thus, the exact relation of behavior to structure is to a large extent unspecified. Current structural computing research still views behavior as something that is orthogonal to structure: something that has to be added on top of it. In this paper, we attempt to create a(More)
Using a dynamic hypermedia engine (DHE), we propose to automate the following features for database systems, both on and off the Web. First we automatically generate links based on the database's relational (physical) schema and its original (non-normalized) entity-relationship specification. Second, the application developer can specify which kinds of(More)
Web applications make increasingly use of services that are provided by external information systems to deliver advanced functionalities to end users. However, many issues regarding how these services are integrated into web applications and how service oriented web applications evolve, are reengineered and refactored are still addressed in an ad hoc(More)
