Bulk XML or CSV file import export

I need a web page and utility class created that allows a user to choose one of multiple data standards defined by 3rd parties [e.g. GoogleBase] (XML or CSV) and either upload the file for insertion into a database, or enter a URL to schedule their feed to be pulled in during cronjob. Upload (configurable supported file types and size) - may use Apache FileUpload Import (XML or CSV) - able to choose standard Convert (CSV to XML) - from one standard to another Export (XML or CSV) - able to choose standard Feeds (XML or CSV) - user-specific URLs to dynamically create feed links for all supported formats Need to locate or create XSD for each XML data standard to validate the datasets. The goal is to leverage existing standards for popular listing sites, allowing import of data in whatever format the user has available. Once they choose the format, the data is loaded into a database (or scheduled to load, then loaded). After the data is loaded, it can be retrieved by dynamically-generated URLs for that user-specific data, with a unique URL for each supported format. For example, a user uploads a real estate listing XML file in a format for Trulia. The data is loaded into the database and the user can then use a feed URL generated to load the data in the format supported by Zillow, Google Base, Oodle, etc. The data store should be flexible enough to handle all formats, leverage XML validation based on XSD to prevent bad data loading, able to drop first row for CSV. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
