How to read this documentation?
This part of the documentation provides an outline of various aspects of the library and can be seen as a tutorial intended to accustom the reader to the use of the library. If the part delineating all the library classes and the related methods can be used as reference to the use of the library, such an introduction is not suited to understand what it is possible to do with Cogitant, how to do it, to know where to look for a given functionality (in which class), to know how to make class extensions, to define new operations, etc.
It is thus recommended to browse this part of documentation before studying in detail the methods offered by each class. Nevertheless, this tutorial includes links towards detailed descriptions and it can be interesting to consult some of these descriptions during the tutorial reading.
More precisely, this part of documentation can be split into four sections:
A first section provides information about the use of the library without getting into a presentation of classes and in particular the Installing Cogitant from source, as well as the Conventions used in the naming of files, classes and methods. The last point mentioned in this section deals with the procedure to follow for Compiling programs using Cogitant, and in particular the issues of header and library files.
The second part more particularly relates to the use of the library in order to build programs and put forward a description of the various features offered by the library: After an overview of the General architecture of the library, features of the Support manipulation are described as well as those for the Conceptual graph manipulation and the Rules and constraints manipulation. Certain operations being possibly incorrect, Cogitant has an Error management. The available Operations are not directly methods of cogitant::graph or cogitant::rule classes but are accessible through specific classes. These classes, subclasses of cogitant::operation, offer the operations defined in the model (projection, application of rules) as well as inputs/outputs operations in various formats, and operations for checking of objects. At last, the library being designed to be widened, the mechanism of Object allocation is described. The use of cogitant::Allocator classes facilitates the definition of new classes from existing classes (by heritage): thanks to these allocators, these new classes can be easily taken into account within the existing mechanisms.
The third section describes two Cogitant extensions: the Client-server architecture as well as the classes allowing the Graph drawing.
Finaly, the last part provides a reference for file formats used in Cogitant, and in particular the BCGCT Format and the CoGXML Format and ends with a Bibliography as well as a list of Latest changes.
Files included in the archive
This section shows a quick overview of the directory and file tree included in the archive.
Directory containing the library documentation. Files of this directory are, for the most part, intended to Doxygen, which is the tool used to generate HTML, PS or PDF documentation.
The DTD for the CoGXML format.
HTML documentation of the library. To consult this documentation, open the file
index.html in your browser.
HTML documentation of the Java API. To consult this documentation, open the file
index.html in your browser.
The DTD of the exchange format between Cogitant's server and client.
This directory contains tutorial "Doxygen sources". You do not need this directory, excepted if you have to modify and regenerate the documentation.
Directory containing head files of the library. Actually, no file resides in this directory, they are all in the
cogitant subdirectory in order to make the copy of this directory in a standard one easier (
/usr/local/include for instance) and to make the files reachable through a

header files of the client-server library extension.
header files of the library extension enabling graph displaying.
header files enabling interfacing with java.
Program examples using the library as well as files containing graphs and supports.
Supports, graphs and rules examples, in the BCGCT format. Each subdirectory contains a support (
bcs extension) and graphs (
