there were few tools of easy use for the daily work in epidemiology&#46; Small utilities were created that allowed the use of computers in the daily work&#46; Epi Info&#44; the most important exponent in the free programs adapted to the epidemiology field was maybe one of these tools that&#44; for its simplicity&#44; it was implanted in the entire world and helped many people to be introduced in the handling of computers or in its epidemiologic intruction&#44; being distributed thousands of copies of the last version of Epi Info for MSDOS&#46;

for diverse reasons &#40;cost&#44; use complexity or formation&#41;&#44; there still being producing free computer tools adapted to the necessities of the epidemiology field&#46; The development of the Internet has increased the capacity of distribution of these programs and has added the concept of Open Source to the already classic concepts of Freeware&#47;Public Domain Software that opens the doors to a bigger collaboration among groups&#47;developers&#46; The objective of the session is to present some of these projects and to open the debate on the difficulty of the development of this type of solutions&#44; to assure its continuity and to facilitate the cooperation among developers&#46;

More than 200&#44;000 copies of the Windows version were downloaded in 2001&#46; There are now hundreds of statistical calculators on the Internet&#44; offering a great variety of functions&#46; For many types of work&#44; the problem is in distinguishing among the various offerings and coping with different data entry screens and methods of documentation&#46; Validation methods for statistical procedures are just beginning to become available&#46; Current trends in software include the use of the Internet and collaborative development of software by users through the process known as Open Source Development&#46; Open Epi is an initiative partly supported by the Gates Foundation to extend the statistical capabilities of Epi Info through Open Source development on the Internet&#46; It will provide a framework for developing epidemiologic calculators in JavaScript&#46; The calculators will run in Windows&#44; Linux&#44; or Macintosh systems under web browsers&#46; They can be used from a web site over the Internet or downloaded and run without an Internet connection or web server&#46; The source code will be the product of a group of contributors and will be included with the programs&#46; Open Epi will provide a framework for epidemiologic software development&#44; with modules for entering summary data in tables&#44; configuring the tables for different authors&#39; preferences&#44; providing the data to user-written statistical modules in standard format&#44; and formatting results as web pages that can be further edited or displayed&#46; Methods will be provided for developing help files&#44; for validating calculations&#44; and for language translation&#46; The talk will include demonstrations of Open Epi and other Internet statistical software for epidemiology and a discussion of the process of Open Source development during the first nine months of the project&#46;

to support and to facilitate the teaching of epidemiology and to improve the analytical tools of health professionals&#46; Version 3&#46;0 has an important qualitative change regarding the previous versions&#46; The work group&#44; more stable and structured&#44; has been a multidisciplinary team&#44; &#40;epidemiologists&#44; statistics and computer professionals&#41; from Galicia&#44; Cuba and Pan-American Health Organization&#46; At first it were defined the scope and the modules of the new version&#46; The development of each module was carried out following a methodology of work&#58; definition of the content&#44; bibliographical search&#44; selection of algorithms&#44; design of screens&#44; programming&#44; tests and corrections&#46; The e-mail communication has been essential among the members of the team&#46; The beta version of each module was tested by an external reviewer&#44; expert in that concrete topic&#46; The help system has been developed with the collaboration of external experts&#46; One of the major difficulties has been the impossibility of maintaining the same programmer during the whole project&#46; The changes of the program can be summarized in relation to the general environment and those referred to the content of the modules&#46; As for the general environment&#44; it has been adopted the Office appearance &#40;incorporating bars for menu and tools&#41;&#46; On the other hand&#44; the hypertext help system has a more didactical and critical focus&#44; including statistical and epidemiological principals&#46; Another important change is the results window that can be edited and saved as RTF format&#46; It incorporate import from other format &#40;dbf&#44; excel or mdb&#41; for all modules&#46; Regarding the technical aspects it has been improved the content of the program substantially&#46; It incorporates common specific techniques that usually are not present in programs of this kind&#46; Briefly&#44; it has 5 new modules&#58; Demography&#44; Probability distributions&#44; Bayesian analysis&#44; Epidemiological surveillance and Meta-analysis&#44; and a substantial improvement of those already existent&#46;

Many of these are working with data in circumstances in e&#46;g&#46; low income countries where modern methods such as fast computers&#44; client server or fast internet are remote&#46; But also in the industrialised countries it can be postulated that the most important resourse is the capabilities of the professional&#44; not of the computer tool as such&#46; The drive to develop the EpiData software tools has therefore mainly been to maintain the working principle of Epi Info version 6 with a very basic file structure known as QES&#47;CHK&#47;REC files&#46; In this working principle many persons around the world have excellent skills which are not directly transferable to other packages&#46; But with development of graphics interfaced programs like windows most users find it hard to cope with the &#34;dos&#34; mode of working in EpiInfo developed until mid 1990&#39;ties&#46; The &#34;small and focused&#34; policy of EpiData started in late 1999 and and has now resulted in freeware tools for dataentry and batch handling of data almost equivalent to the Epi6 datahandling&#44; but extended with features to enhance data documentation&#46; EpiData was completely developed outside formal institutions &#40;apart from the early start&#41; and is now released by the EpiData Association formed by interested persons and the core development team&#46; An international support group &#34;Friends of EpiData&#34; has been established to ensure funding and proper dissemination in local public health&#46; The international collaboration has resulted in translation to over 10 languages and there are currently about 12-1500 downloads of the main program per month from www&#46;epidata&#46;dk going to around 100 countries&#46; The future development of EpiData focuses on developing tight&#44; compact files which can easily be transported around the world&#44; e&#46;g&#46; size is less than one floppy of 1&#46;4 Mb&#46; Further planned functionality is 1&#46; A basic analysis tool EpiAnalysis 2&#46; Tools for transaction logging to meet formal data requirements&#46; Possibly other aspects will follow such as menuing tools&#46; Aspects for discussion in the seminar will be items such as &#34;avoiding reinvention of the wheel&#34;&#44; &#34;experiences with shared responsibility without payment&#34;&#44; &#34;how to balance user influence and clarity&#34;&#44; &#34;minimal administration&#34;&#44; &#34;balance of support and documentation&#34;&#44;
