FRAMEWORK FOR PORTABLE DATABASE APPLICATIONS ---------------------------------------------------------------------- by Darren Duncan CONTENTS * Preface * Keeping Up To Date * Requirements * Installation * Support * To Do * Author PREFACE The "Rosetta" distribution features mainly the Perl 5 modules named "Rosetta", "Rosetta::Schema/::*", and "Rosetta::Engine/::*", but also some related modules like "Rosetta::Driver" and "Rosetta::Driver::Native". These constitute the "core" of the Rosetta framework, for RDBMS-generic apps and schemas. To get the most out of Rosetta, please also install the "Rosetta-Drivers" distribution, which includes RDBMS-specific glue that adapts Rosetta to work with various database products. Alternately, third parties may have released Rosetta drivers (subclasses of Rosetta::Driver) in other distributions. An optional addition is the "Rosetta-Emulators" distribution, which is an extra layer on top of the Rosetta core that emulates the APIs of other database accessor modules so that existing apps can use Rosetta as a drop-in replacement for them. Another option is "Rosetta-Applications", which constitutes stand-alone "example" or "utility" applications built on Rosetta. (Note that the previous two paragraphs are notes for the future; the other distributions don't exist yet.) All of my modules have complete POD inside of them, so please refer to that for a description of module-specific details such as their method APIs. The file "Rosetta::Framework.pod" contains the main POD documentation for the Rosetta framework taken as a whole, including the purpose and overall design structure of the distribution; it should be read first. This Read Me document concerns itself mainly with installation and support issues, and also includes any "To Do" lists. KEEPING UP TO DATE My module set is constantly under development. You should be able to find the newest versions at my website, "http://www.DarrenDuncan.net", on the page called "Perl Libraries I Made" (name subject to change). They can also be found on CPAN under the author name of "DUNCAND". I am inclined to update the copies on my web site more often, but those intermediate versions are more likely to have been tested less, and the modules may be updated day by day without increasing the version numbers. However, the copies on CPAN are guaranteed to have unique version numbers when the module has changed. REQUIREMENTS All of my modules require Perl 5.004 or newer, even though only some of them need it, in the interest of consistency. That said, Perl 5.004 is already 3 years old, is available as a binary on practically every OS that supports Perl at all, and is a very solid release, so I see no reason to support anything older. The Rosetta core modules don't require anything else. INSTALLATION To install these modules, cd to the directory that contains all of the extracted distribution files, including this ReadMe file, and type the following: perl Makefile.PL make make test make install The last step probably won't work if you are not the administrator of your machine; in that case you either need to get your administrator to install this for you, or put it in a your own local directory instead. The Makefile.PL can do this for you if you substitute something like the following for the first line above: perl Makefile.PL PREFIX=/tmp/myperl5 or: perl Makefile.PL PREFIX=/home/me/myperl5 If you are on a Mac system that is older than Mac OS X (Mac OS 9 or earlier) and/or you are otherwise having problems with the Makefile, you can still install this module the old fashioned way, by copying. Every file in the "lib" folder of this distribution goes in its corresponding location within the "lib" folder that came with your Perl 5 distribution. Or alternately, put them anywhere you want, but you will need to have that location added to your include path by your main program using something like this: use lib '/home/me/myperl5/lib'; Then you would want to run the included test program to make sure the module is installed correctly. Call it with: perl -w t/Rosetta.t Any existing POD is embedded in the module itself. The Makefile probably extracted it for you in the usual manner, or you can run a POD extractor on it yourself to the same effect. You can also find an HTMLized copy of the POD on CPAN and other public source archives; I link to one copy of it on my web site. SUPPORT Currently I don't have any support arranged with other people, lists, newsgroups, or otherwise. Feel free to ask me if you can't figure things out on your own, or another person whom you know has used this. I may start a mailing list for support issues later, so that users of my modules can help each other with them. TO DO * Everything, more or less. AUTHOR Copyright (c) 1999-2003, Darren R. Duncan.
