Introduction Many popular web sites used by population such as Amazon, Yahoo and Google they are example of a OSS/FS which is classified as free software. Today’s nurses have an ever increasing choice of possible software solutions to meet their computing and networking needs.

History :

History In the 1950s, 1960s, and 1970s, it was normal for computer users to have the freedoms that are provided by free software. Software was commonly shared by individuals who used computers and by hardware manufacturers who were glad that people were making software that made their hardware useful

PowerPoint Presentation:

Organizations of users and suppliers were formed to facilitate the exchange of software; see, for example SHARE and DICUS. By the late 1960s change was inevitable: software costs were dramatically increasing, a growing software industry was competing with the hardware manufacturer's bundled software products (free in that the cost was included in the hardware cost), leased machines required software support while providing no revenue for software,

Theory Of OSS/FS:

Theory Of OSS/FS The two major philosophies in the OSS/FS world is the FSF philosophy and the open source initiative or “OSI”.OSS/FS is contrasted w/proprietary or commercial software.

PowerPoint Presentation:

Proprietary Software- is that on w/c an individual or a company holds the exclusive copyright. Commercial software- is a software developed by businesses or individuals w/ aim of making money from its licensing and use.

Some Common Acronyms & Terms:

Some Common Acronyms & Terms OSS –Open Source Software OSS/FS- Open Source Software/Free Software FOSS –Free and Open Source Software FLOSS- Free/ libre/ Open Source Software GNU/LINUX- the complete operating System including the linux kernel , the GNU components and other programs.

PowerPoint Presentation:

FREE SOFTWARE Is a matter of the users’ freedom to run copy, distribute, study, change, and improve the software in any way they wish. A program is only free software if users have all of these freedoms.

Four Kinds of Freedom For the Users::

Four Kinds of Freedom For the Users: The freedom to run the program for any purpose The freedom to study how the program works and adapt to your needs The freedom to redistribute copies , so you can help your neighbors The freedom to improve the program and release your improvement to the public


OPEN SOURE SOFTWARE OSS is any software that satisfies the open software initiative’s definition. The open source concept is said to promote software reliability and quality by supporting independent peer review and rapid evolution of source code , as well as making the source code of software freely available.

The Open Source:

The Open Source 1. Free Redistribution The license shall not restrict any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources. The license shall not require a royalty or other fee for such sale.

PowerPoint Presentation:

2. Source Code The program must include source code, and must allow distribution in source code as well as compiled form. Where some form of a product is not distributed with source code, there must be a well-publicized means of obtaining the source code for no more than a reasonable reproduction cost preferably, downloading via the Internet without charge.

PowerPoint Presentation:

3. Derived Works The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software .

PowerPoint Presentation:

4. INTEGRITY OF AUTHOR’S SOURCE CODE The license may restrict source-code from being distributed in modified form only if the license allows the distribution of "patch files" with the source code for the purpose of modifying the program at build time. The license must explicitly permit distribution of software built from modified source code.

PowerPoint Presentation:

5. No Discrimination Against Persons or Groups The license must not discriminate against any person or group of persons .

PowerPoint Presentation:

6. No Discrimination Against Fields of Endeavor The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.

PowerPoint Presentation:

7. Distribution of License The rights attached to the program must apply to all to whom the program is redistributed without the need for execution of an additional license by those parties.

PowerPoint Presentation:

8. License Must Not Be Specific to a Product The rights attached to the program must not depend on the program's being part of a particular software distribution. If the program is extracted from that distribution and used or distributed within the terms of the program's license, all parties to whom the program is redistributed should have the same rights as those that are granted in conjunction with the original software distribution.

PowerPoint Presentation:

9. License Must Not Restrict Other Software The license must not place restrictions on other software that is distributed along with the licensed software. For example, the license must not insist that all other programs distributed on the same medium must be open-source software.

PowerPoint Presentation:

10. License Must Be Technology-Neutral No provision of the license may be predicated on any individual technology or style of interface.

Benefits of OSS/FS :

Benefits of OSS/FS As OSS/FS can be obtained royalty free ,it is less expensive than proprietary alternative. OSS/FS projects tends to support open standards & provide a level playing field, expanding the market by giving the software greater choice. Including reliability or stability and developing local software capacity.

Issues in OSS/ FS :

Issues in OSS/ FS Licensing Copyright and Intellectual Property Total Cost of Ownership ”TCO” Support and Migration Business Models Security and stability

PowerPoint Presentation:

TOTAL COST OF OWNERSHIP(TCO) -Is the sum of all the expenses directly related to the ownership and use of a product over a given period of time. SUPPORT AND MIGRATION -The European Union(EU) has published a document entitled the “IDA Open source Migration Guidelines ” that provides detailed suggestions on how to approach migration.

PowerPoint Presentation:

SECURITY AND STABILITY -there is no perfectly secure operating system or platform; factors such as development method , program architecture , target market can greatly affect the security of system and consequently make it easier or more difficult to breach . Security of information is vitally important in the health domain , particularly in relation to access , storage and transmission of patient records.

OSS/FS application :

OSS/FS application Operating System Web Browser E- mail client Word Processing Presentation Tools

Operating System :GNU/Linux :

Operating System :GNU/Linux GNU/Linux is a term that is increasingly used by many people to cover a distribution of operating system and other associated software components.

PowerPoint Presentation:

E- mail: sendmail (e-mail server) An email server function is to deliver user e-mail to its destination ,and send mail began development in 1982 at the university of California .

OSS/FS Health Care Application:

OSS/FS Health Care Application OpenEHR FreeMED OpenEMR CARE2xs

PowerPoint Presentation:

OpenEHR The openEHR is an international, not for profit organization that is working toward the development of interoperable . It was created to enable the development of open specifications ,software and knowledge resources for health information system.

PowerPoint Presentation:

FreeMED Is a flagship product of the freeMED Software foundation . It is the result of many years of work in developing an OSS/FS electronic medical record and billing system.

PowerPoint Presentation:

OpenEMR OpenEMR is freer open source medical clinic practice management (PM) and EMR application.

PowerPoint Presentation:

CARE2x Care2x is one of the few OSS/FS projects to have been originated by a nurse . It aims to develop a practical, integrated healthcare information system.
