The above diagram shows the first main feature of ORPHEO:
The second main feature is hypertext generation and management:
The full power of ORPHEO lies in the fact that its diagrams may be used, not only to display bits of knowledge, but also to generate hypertext (HTML) pages, and their hyperlinks.
The main objective at the present time is to assist intensive procedure and document users - typically, project managers, engineers or operators - at two levels:
Document design and maintenance
ORPHEO is a generic tool for developing object-oriented repositories of unstructured data - data that doesn’t easily fit in standard databases - such as text and graphical information. It is in principle applicable to any type of unstructured data (that may concern, for instance, expert technical knowledge as well as ordinary procedures).
An interesting application would be to couple the procedure consultation system to a process so as to provide the engineer or operator with a context-dependent view of the relevant procedures.
ORPHEO models help the document (or web-site) manager, as well as the end-user.
ORPHEO addresses two crucial problems in document management: the problem of hyperlink management and the problem of updates (because of redundancies and multi-authoring, it is not easy to know where to make a modification).
With ORPHEO, the structure of the hypermedia document is always generated from the graphical diagrams, as illustrated in the following figure. Such diagrams automate the management of hyperlinks, eliminate repetitions in the text, making it easy to see where changes should be made.
Diagrams also provide extensive support for reuse: reuse of already defined objects, by versioning; and reuse of presentation styles that may be attached either to an element of a page (e.g., standard title format) or to the page itself (e.g., standard headers and footers).
Document consultation also involves its own set of problems:
The ORPHEO approach allows the end-user to:
Services we offer
Around the tool itself, we have developed a methodology that provides guidelines for designing and maintaining an ORPHEO application. We offer training sessions and design support, as well as concrete solutions to problems such as:
