Sending a discovery agent to a computing device determines the services provided by that first computing device. As a result, a first set of information is received from the agent that provides information indicative of the services provided by the computing device. That information can then be compared to other information, either from the same computing device at a different point in time, or from a second computing device. The other information is indicative of services performed by that computing device at a different point in time or the second computing device. From that, services provided by the computing device that were previously different on the first computing device or that are not available on the second computing device can be determined.

Remote discovery and system architecture

An embodiment of the present invention is a technique to provide time sensitivity to an inference engine. A time function is associated to an event object and a rule object in a rule engine using a dynamic object. The event object represents one of an event and a fact. The rule object represents a rule associated with the event object. Time-related information on the dynamic object is obtained using a timed fact object and the time function. The timed fact object corresponds to the event object. A time queue containing the timed fact object is updated using the time-related information. The updated time queue updates status of a condition of the rule.

Providing time sensitivity to an inference engine

A method is disclosed for use in a software development framework having a repository and at least two software systems. The repository contains a meta-model and the software systems, which store instances of the meta-model. The method enables exchange of the instances of the metadata among the software systems using a generalized data transfer language. The method comprises the steps of extracting a fixed component and a list of repeated components of the metadata; extracting a variable component form the list of repeated components; parsing the variable component into a first set of constituent components for a first instance of the variable component; and, determining the hierarchical order and inheritance of the first set of constituent components in the list of repeated components. Next, each of the first set of constituent components are transformed into corresponding components of the generalized software language. The first instance of the variable component is then transformed into corresponding components of the generalized software language. The list of repeated components is updated and the previous five steps are repeated for another instance of the variable component. The list of repeated components are next transformed into corresponding components of the generalized software language. After this, the fixed components are transformed into corresponding components of the generalized software language. Finally, the corresponding components are distributed to the second instance of the software model.

The fixed components are then transformed into corresponding components of the generalized software language. After this, the corresponding components are distributed among the software systems, where they are used as the format specification for the generalized data transfer language transport of the instances of the meta-model among the software systems.

Method for generating simple document type definitions

A method is disclosed for use in a software development framework having a repository and at least two software systems. The repository contains a meta-model and the software systems, which store instances of the meta-model. The method enables exchange of the instances of the meta-model among the software systems using a generalized data transfer language. The method comprises the steps of extracting a fixed component and a variable of the meta-model; parsing the variable component into a first set of constituent components for a first instance of the variable component; and extracting a list of repeated components from the first set of constituent components. Next, each of the members of the list of repeated components is transformed into components of a generalized software language. Then, the first set of constituent components are transformed into corresponding components of the generalized software language. The first instance of the variable component is then transformed into corresponding components of the generalized software language. The previous five steps are repeated for additional instances of the variable component. After this, the fixed component is transformed into corresponding components of the generalized software language. Then, the corresponding components are distributed among the software systems. The distributed components in the generalized software language can then be used to control the syntax of the generalized data transfer language when used to exchange instances of the meta-model.

Method and system for generating a compact document type definition for data interchange among software tools

A method useful in a computing system that has at least one server and a multiplicity of clients coupled thereto by means of a network. The server has a repository coupled to it for storing SCL of a legacy Form and at least one of the clients executes a Web browser program. The method operates in the same client that the Web browser operates and is invoked by the Web browser program for supporting the exact reproduction of the legacy Form. SCL Text is parsed to obtain a sequence of SCL Constructs, some of which contain information relating to GUI Controls of the legacy Form. For each SCL Construct with a GUI Control to be displayed, a GUI Control is painted by using type and positioning information derived from each of the SCL Constructs, respectively. Font information from the SCL Construct is used to set font characteristics of the GUI Control and user inputs are interpreted to navigate from GUI Control to GUI Control. Finally, the user inputs are interpreted to invoke a process that sends contents of the GUI Controls to the host application.

A method in a computing system having at least one server and a multiplicity of clients coupled thereto by means of a network. The server executes a Web Server program and at least one of the clients executes a Web browser program. The method operates in the server and at least one of the clients for supporting dynamic access to objects stored in the server repository by the Web browser program. The method begins in the client by parsing Form description language to obtain references to objects stored in the server repository. For each reference to an object stored in the repository, a message is constructed for the Repository Object for transmission to the Web server. Within the Web server the message is used to retrieve the contents of the Repository Object from the server repository. Next, the retrieved contents of the Repository Object is returned to the client for association with its Data Name. Next, a GUI Control is located that is associated with the Data Name; and, the contents of the Repository Object are placed into the GUI Control located in the previous step. Accordingly, a Form is displayed with GUI Controls filled in with values from the server repository.

Method for dynamically embedding objects stored in a web server within

A method operating in a computing system that has at least one server and a multiplicity of clients coupled thereto. The server has a CPU executing a Web Server program and a repository coupled thereto for storing description language of a Form to be displayed. The server is coupled to a host having a CPU executing a legacy application containing the Form. At least one of the clients executes a Web browser program. The method of the present invention operates in the server and the client for supporting enterprise application data binding. The method in the server includes the steps of opening the Forms and requesting a first Form and associating data names with data values received from the host and sending them to the client. The client then locates a corresponding GUI Control and makes an association between each of the data names and a corresponding GUI Control and obtains the contents of each of the corresponding GUI Controls associated with a data name and places data value/data name into a buffer, Next, the server processes the contents of the buffer and sends it to the host, whereby the GUI Controls are displayed containing values and states from the Form.

Method for extending the hypertext markup language (HTML) to support

The disclosed invention is a method for generating code in a maintainable form and in performing needed maintenance for the same. This method is useful in a computing system having at least one server and a multiplicity of clients coupled thereto by means of a network. The server includes a CPU executing legacy programs and at least one storage device for storing forms of the legacy program. The generated code implements the host forms while allowing for additional logic to be added. The method of this invention operates in at least one of the clients for generating code for modifying existing event routines for controls on the forms. Moreover, the code generated by the method of this invention is separated from additional logic added by a programmer, and this programmer-added logic is retained even as the generated code is revised.
