Abstract

A set of hypermedia linking services enable client applications to incorporate hypermedia capabilities in an open system architecture. The users are provided with a consistent hypermedia interface completely managed by the hypermedia services and not by the client application itself. The graphical user interface includes methods for menu handling, dialog box presentation and pointing device message handling, e.g., mouse message handling. Normal hypermedia activities such as object management, object creation, object deletion and object modification is provided. In addition, an open system searching mechanism is provided to satisfy broad non-context requests for information by the user without sacrificing the advantages of an open hypermedia environment.

Claims

1. A method of providing hypermedia link marker abstract and search services in an open hypermedia system in which data for individual applications may be displayed on a screen of a display device in an application window, each of said windows including a main application workspace in which said data is displayed, said hypermedia system providing a uniform and consistent graphical user interface for applications which utilize hypermedia services available from said open hypermedia system, said method comprising the steps of:

providing an open hypermedia system which allows any application to participate in linking, allowing a seamless integration of applications and application-rendered data developed totally independently from one another;

prompting a user to input information to create a link marker within an application window, said link marker being bidirectionally linked to one or more other link markers and/or unidirectionally linked to objects not written for said open hypermedia system;

providing the user with an option to input a link marker abstract in the form of summary text associated with the link marker; and

maintaining a database of said link markers and link marker abstracts.

2. The method recited in claim 1 wherein said link markers contain text indicating information located at other ends of the link marker'"'"'s links.

3. The method recited in claim 2 further comprising the steps of:

displaying a dialog box on said display device for inputting data to be searched;

searching said database link markers and abstracts in response to data input by a user; and

displaying a list representing link markers in said database of data matching said input data.

4. The method recited in claim 3 wherein said data input by a user is text which may be a keyword, phrase or sentence.

5. The method recited in claim 3 further comprising the steps of:

accepting a user input selecting a location in said list; and

navigating to data in said database corresponding to a selected location in said list.

6. The method recited in claim 5 wherein if said data in said database corresponding to a selected location in said list is data of a second application, further comprising the step of displaying said data within an application window of said second application.

7. The method recited in claim 6 wherein if said second application is not currently running, further comprising the steps of:

launching said second application; and

opening an application window on said screen for said second application.

8. A system providing hypermedia link marker abstract and search services comprising:

an open hypermedia system which allows any application to participate in linking, allowing a seamless integration of applications and application-rendered data developed totally independently from one another, said open hypermedia system displaying data for individual applications on a screen of a display device in an application window, each of said windows including a main application workspace in which said data is displayed, said hypermedia system providing a uniform and consistent graphical user interface for applications which utilize hypermedia services available from said open hypermedia system;

means for prompting a user to input information to create a link marker within an application window, said link marker being bidirectionally linked to one or more other link markers and/or unidirectionally linked to objects not written for said open hypermedia system;

means for providing the user with an option to input a link marker abstract in the form of summary text associated with the link marker; and

means for maintaining a database of link markers and link marker abstracts.

9. The hypermedia system recited in claim 8 wherein said link markers contain text indicating information located at an end of the link marker'"'"'s links.

10. The hypermedia system recited in claim 9 further comprising:

means for displaying a dialog box on the screen of said display device for inputting a user data to be searched;

means for searching said database link markers and abstracts in response to data input by the user; and

means for displaying on said screen a list representing link markers in said database of data matching said input data.

11. The hypermedia system recited in claim 10, wherein said data input by a user is text which may be a keyword, phrase or sentence.

12. The hypermedia system recited in claim 10 further comprising:

means for accepting a user input selecting a location in said list; and

means for navigating to data in said database corresponding to a selected location in said list.

13. The hypermedia system recited in claim 12 further comprising means for displaying said data in said database corresponding to a selected location in said list within an application window of a second application if said data of said second application.

14. The hypermedia system recited in claim 13 further comprising:

means for launching said second application if said second application is not currently running; and

means for opening an application window on said screen for said second application.
