Oracle Media Objects, formerly Oracle Card, was a software development tool for developing multi-media applications, with functionality and appearance similar to Apple Inc.'s HyperCard. The program originated as Plus, a 1989 clone of HyperCard published by Format Verlag that added several highly-requested features. Plus was purchased by Spinnaker Software, who ported it to Windows NT and OS/2 Presentation Manager, becoming the first cross-platform hypermedia solution. In 1994, Plus was purchased by ObjectPlus, who focussed on the Windows version, renaming it WinPlus. They also licensed the system to Oracle, who used it as the basis for Oracle Card. First released in 1991, Oracle Card was essentially a redistribution of the Plus runtime engine along with external libraries for establishing connections to RDBMS engines such as Oracle and DB2. As such, Oracle Card stacks could execute queries and associate their results with native variables, making Oracle Card one of the first RDBMS application development environments to support cross-platform development. The initial release was important as it was a stop gap measure to allow Oracle to provide some support for Microsoft Windows which was rapidly growing in popularity in business. At this time Oracle's core technologies for creating data entry systems (Oracle Forms and Oracle Reports) only ran in DOS and did not provide a GUI interface for Windows. Oracle Card helped to show that Oracle was supporting Windows until it could release its first Oracle Forms 4.0 with improved GUI support for Windows. A few years later, Oracle acquired the original Plus source code from Format Verlag and developed it to become Oracle Media Objects or OMO. OMO lasted only briefly, with development ceasing after version 1.1.2. OMO was used by Oracle to position itself in the video on demand market. Commercially, there were very few products built using the tool. Amongst these were the "Our Secret Century" series of CD-ROMs published by The Voyager Company, Inside Independence Day by ACES Entertainment and UCAS University Course Search a CD-ROM by Learning Information Systems trading as StudyLink. Unique Features of OMO OMO had the unique distinction of not only its stacks being cross-platform, but also its external libraries (XCMDs). For that purpose, a small subset of the Mac OS memory management commands (Handles) were ported to other platforms. In addition, OMO sported a modular design where every type of object was actually implemented as a plugin file in an "Objects" folder. OMO's object
