PHP Library for public use

Hello, I am Vinay Chitale from hexagon Software. We are using PHP for last 4 years for website development. Recently we developed three classes 1.Document.class : For faster development of data entry pages, either template based or without template based, with builtin javascript validation and many other features 2.Report.class : To generate reports quickly with built in features for page navigation, selection of records per page option, column sorting and three standard columns edit, delete and srno. Optionally this class also supports ajax to swich from one page to another without page submission. 3.CSV-FileUpload.class :This class allows user to do setup and then using that setup it uploads the csv file. From programming point of view, there is not much coding required, call Setup for setup screen and upload to upload csv file. Till now we are using these classes for our internal development purpose. But I think making them available for other developers might be helpful. I would like to know wheather I can put them on your site. Also How my intellectual property rights can be maintained ? Regards Vinay Chitale
