Enforcing Strong Object Typing in Flexible Hypermedia - Furtado, Madeira (Correct)
....their contents. The user is offered a graphical means to express the queries. Our investigation focused on how to provide type emergent features that are easy to use and automate the process for repetitive data. But in contrast with previous work on this issue (Viki [10] 11] Dolphin[5] Cowfish [21]) we do not settle for slotted frames of information. Instead, the user is encouraged to create object types in an intuitive way. We are especially concerned with enforcing strong typing to achieve as much as possible database integration of the emergent structures. This way, we outline the path ....
....flexibility to the user organizing the content holding entities, supports structure emergence and also some degree of structure recognition. Similarly, Dolphin [5] also supports structure emergence, the coexistence of different degrees of formality and mutual transformation between them. Cowfish [21] extends Sepia activity spaces [18] into flexible metamodel activity spaces in which the user flexibly specifies types. These systems also use a frame based approach: Sepia uses a frame model with object oriented frame representations similar to Aquanet or MacWeb [13] Dolphin [5] uses nodes as ....

.... we add a third layer on top that provides process support services (i.e. in the form of a cooperative activity space called process space) Activity Space The foundation of this work is a hypermedia meta model for representing task specific hypermedia spaces, which we call activity spaces [24]. The basic elements of the meta model are links, nodes, node content pages, and other media objects. The meta model describes an activity space from three semantics: structural, relational, and computational. Structural semantics describe the graph type of a hypermedia structure. Along this ....
....a page. The shade under a page indicates that there is a page schema for each page. The structure of a composite is determined by its root node page schema, because the structures of its components are recursively defined along embedded organizational links. For details on activity spaces see also [24]. Process Space In this section we introduce the components for modeling processes. Abstractly speaking, both the logical structure of a workflow process and a hypermedia network can be seen as a directed graph. This makes the correspondence between many workflow concepts and hypermedia concepts ....

An artifact may be hierarchically structured, and the structure of aggregated artifacts can be defined in an artifact definition tool, which is a part of the COWFISH system [Wang Haake 97] Definition of collaboration protocols: A collaboration protocol is described like a state transition diagram where a node may contain a sub diagram describing the state represented by that node in more detail. A state node in a diagram represents a state within the collaboration protocol. A ....

A cooperative activity space provides multiple users with synchronous or asynchronous access to a shared hypermedia workspace (Streitz et al. 1992) In addition to access, cooperative activity spaces provide group awareness by showing collaborators presence and activities in the shared ....

For example, a product design model or an argumentation model can be defined in an activity space which can be instantiated to capture specific design or argumentation structures. An activity space instance provides support for creating information spaces consisting of instances of allowed ....
....capture specific design or argumentation structures. An activity space instance provides support for creating information spaces consisting of instances of allowed object types, limiting its organization to allowed structures, and potentially offering task specific operations. The COWFISH system [23] extends the SEPIA [10, 21] activity space concept into a meta model for defining hypermedia based activity spaces. The elements of the meta model are nodes, links, node content pages, and other media objects such as text, drawing, graphics, image, source code, etc. An activity space is ....

....in a design model base. This base can be used to define other activity spaces. As mentioned above, designers may need to define their own design model at run time. The design model is usually transformed gradually from informally structured information space into more formal structures. COWFISH [12] is a system, in which a flexible hypermedia model has been developed for representing activity space semantics. A flexible hypermedia system is a hypermedia system which supports the co existence and transformation of information structures in different degrees of formality, i.e. from ....
