Anderson E. James Whitehead, Jr. Professor Richard N. Taylor Arcadia Project U.C. Irvine November 15, 1994 -------------------------------------------------------------------------------- ANNOUNCEMENT: The Arcadia Project at the University of California, Irvine, announces the release of version 1.0 of the heterogeneous hypermedia system, Chimera. GENERAL OVERVIEW: Chimera is an open, serverized, hypermedia system that supports n-ary links between heterogeneous tools and applications in a network. Objects manipulated by separate applications can be linked together through Chimera. From the user's standpoint, for example, while working with one object in one application, an anchor on the displayed object may be selected, causing another application to start up, displaying a related (linked) object. Chimera comes with bindings to C and Ada; bindings to several popular tools have been constructed. Chimera makes no assumptions or demands regarding user interface system employed or how or where objects are stored. Chimera embodies the following technical attributes: Heterogeneous object editor & viewer support: Many different applications can be integrated with Chimera allowing them to participate in a hyperweb. Anchors specialized to particular views: Chimera handles just the links between objects and not their display, thus the applications which display the objects can make the display of anchors customized to the views of the objects. Multiple-view, concurrent, and active displays: Chimera has a client-server architecture. The Chimera server handles connections from client applications and handles the routing of messages (e.g. link traversals) between them. Links across heterogeneous object managers: Since an application manages the access and display of an object, and since anchors are created with respect to an object's view and not directly on an object, links between objects stored in different object managers (or even a file system) are easily established. n-ary links: A link is not restricted to a source and destination. Instead, links are modeled as a set. One anchor can take a user to multiple destinations in Chimera and all of them can be viewed at once (limited only by screen real estate). Chimera comes with application programming interfaces (APIs) for clients written in the Ada and C programming languages. In future releases we plan to provide additional APIs for C++, SmallTalk, and tcl. HARDWARE REQUIREMENTS: We built and tested Chimera on Sun hardware running SunOS 4.1.3. SOFTWARE REQUIREMENTS: In order to compile the C API, you will need a C compiler such as gcc. The C API can be used along with the binary release of the server on platforms that do not have a SunAda compiler. In order to compile the source release and/or the Ada API, you will need the SunAda compiler version 1.1 or later. For the source release you will also need Q version 3.2, and Arpc version 402.3. Q and Arpc are systems built by the Arcadia project at the University of Colorado, Boulder. Instructions for obtaining these two systems are included in the INSTALL file of the release. You will need the program gzip to uncompress the tar files described below. gzip can be obtained from any GNU software ftp site. AVAILABILITY: Chimera is available via anonymous ftp: Host: liege.ics.uci.edu Directory: pub/arcadia/chimera Two files are available: chimera.1.0.tar.gz: A tar file compressed using gzip containing the full source release of Chimera. chimera.1.0.bin.tar.gz: A tar file compressed using gzip containing a binaries release of Chimera which includes the source code for the two APIs and the chimera server/support tools executables. Obtain the former if you want access to all of Chimera's source code. Obtain the later if you are more interested in integrating clients with Chimera and don't really care how the Chimera server is implemented. CONTACT INFORMATION: All feedback is welcome at chimera-local@ics.uci.edu. All bug reports are welcome at chimera-bugs@ics.uci.edu. We shall attempt to contact you as quickly as possible in response to your mail. WWW INFORMATION: The release and more information about Chimera and Arcadia in general is available on the World Wide Web.
