OSWorkflow 2.8.0 is considered as a smart and useful application that is known as a "low level" workflow implementation written in Java. It does not use a graphical tool for developing workflows, but can be configured by writing a xml file as the main conf file for the workflow process.

Graphical solutions dont provide the flexibility to properly fulfill all requirements in a full-blown application. In this way the programmer can go in and customize the OSWorkflow after his specific needs.

Situations like "loops" and "conditions" that might be represented by a graphical icon in other workflow systems must be "coded" in OSWorkflow.

Major Features:

Compiling from CSV: To get the latest version of OSWorkflow,it is recommend that the source via CSV is to be downloaded and compiled using the Jakarta Ant build script provided there. Compiling OSWorkflow from source is trivial with the following ant targets:

1. jar (default) - compiles the library osworkflow.jar
2. example-war - compiles and assembles osworkflow-2.8.0-example.war, which is configured to use memory persistence and should deploy without any configuration into most web containers.
3. example-ear - compiled and assembles osworkflow-2.8.0-example.ear, which is a J2EE application that is configured to use osworkflow with the EJB persistence store. Some configuration of data sources is required, as well as a full J2EE application server.
4. client-jar - compiled and assembles designer.jar, which is a Swing GUI workflow designer application that can be used to visually inspect and edit workflows.

SWI-Prolog 5.7.12 is very useful because it offers a comprehensive Free Software Prolog environment, licensed under the Lesser GNU Public License. Together with its graphics toolkit XPCE, its development started in 1987 and has been driven by the needs for real-world applications. These days SWI-Prolog is widely used in research and education as well as for commercial applications.

Major Features:

1. Kernel licensed under the LGPL. Prolog libraries are distributed under the GPL with an additional statement that allows for use in proprietary applications. Details can be found on the license page.
2. fast compilation. E.g., loads 140,000 lines of code spread over 500 source-files in 2.3 seconds on an AMD 5400+ system.
3. Robust and free of memory leaks. In use for several servers that run 24x7.
4. Small. The full development environment, including graphics, libraries and many interface packages requires approx. 40MB harddisk. The non-graphical kernel is about 650Kb, the graphics library adds about 1.2Mb to the image.
5. Scales well for large applications. No limits on program size, atom-length, term-arity or integer values. No performance degradation on predicates with many (indexed) facts.
6. Unbounded integer and rational number arithmetic based on GMP library.
7. Comprehensive set of built-in predicates, covering Part 1 of the ISO standard, the de-facto Edinburgh Prolog standard and important parts of Quintus and SICStus Prolog. Fair compatibility to Ciao, YAP and GNU-Prolog.
8. Flexible and fast interface to the C- and C++-Language. The interface allows for calling both-ways, handling of non-determinism both ways and embedding of the SWI-Prolog kernel in C/C++ projects.
9. The goodies: modules (upward compatible to Quintus and SICStus), garbage-collection (transparent to C/C++-code, including atom garbage collection), last-call optimisation, Dynamic expansion of the runtime stacks, ISO exception-handling (including C/C++ interface for catching and throwing exceptions).
10. Execution profiler (time and call statistics) for Linux, most Unix platforms and Windows NT/2000/XP/Vista.
11. Cross-Referencer. gxref/0 provides a graphical front-end for the extensible Prolog cross-referencer (xref).
12. Portable to many platforms, including almost all Unix/Linux platforms, Windows (NT/2000/XP/Vista, including 64-bit editions), MacOS X (using X11 for graphics) and many more. Both 32-bits and 64-bits hardware is supported. Sources are plain C99, configured automatically using GNU autoconf (configure, make, make install).
13. UNICODE character set handling internal. Ideal for web- and international applications.
14. Machine-independent saved-states (save on one platform, run using the virtual machine of another platform).
15. Multi-threading support: run multiple pre-emptively scheduled prolog engines on the same database.
16. attributed variables, coroutining (freeze/2, when/2, dif/2), global variables, cyclic terms. Flag-controlled handling of occurs-check (on/off/error) see current_prolog_flag/2.
17. Constraint Logic Programming, providing libraries for CHR (Constraint Handling Rules), clp(FD), clp(R,Q) and various others.
18. Bundled with interface libraries for Java (JPL), ODBC, TCP/IP sockets, SSL, CGI form handling, etc.
    
19. Multi-threaded Web server library with comprehensive libraries to generate HTML, HTTP authorization, session management, exchanging JSON (used by many AJAX widgets), etc.
20. Fast and flexible libraries for parsing SGML/XML (HTML), parsing RDF, store and query the RDF triple model. A graphical editor for RDF/RDFS and OWL models called Triple20 is distributed seperately.
21. Literate programming support through PlDoc. Provides integrated view on manual and application documentation and producing LaTeX documentation for your application.
22. Unit testing support through PlUnit.
23. Regular binary distributions for most popular platforms (Windows (32/64 bits), Linux (32 bits) and MacOS X (32 bits)).
24. Regular distribution of the full source packages. The sources are also accesible through GIT.

YaYacc 1.0.1 is such a useful and great syntactical analyzer, which is compatible with original on algorithm analysis and perceived language with yacc. It generate C++ code. Resulting code can be used in multithreaded applications.

Major Features:

YaYacc guarantees:

1. Transmission of yacc descriptions to template code on C++ language.
2. The work of the resulting code the same algorithm LALR(1) as yacc.
3. Object-oriented method of integration with a lexical analyzer.
4. The method of integration with resulting application is incapsulated into object Parser, which gives the result of analysis.
5. The possibility of using some syntactical analyzers for several different input languages in one programm.
6. The possibility of a parallel implementation of some syntactical analyzers the same input language without mutual interlock.
7. The possibility of request destruction for objects in stack of analyzer is foresees during restoration from mistakes.
8. The programm guarantees the possibility of embedding of generated programms in systems, with are functioning 24 hours. The module returns the correct messages about mistakes when configuration or requirements are incorrect; and remain capable to execution other requirements. This fact confirms the reliabity of programm.
9. Supported platforms:
   
   • The operational system: FreeBSD
   • The compiler for yayacc: ANSI C.
   • The operation system for a resulting code: any
   • The compiler for a resulting code: ANSI C++.
