General details:
Program capable of doing everything one needs for scientific research in terms of organizing bibliographies, quotations, files and information sources, including
- storing bibliography data (DONE),
- managing file attachments (Store and access files DONE, open files with OS Standard program DONE),
- exporting into open and human readable bibliography format bibtex (DONE),
- managing multiple users, including registration, login and encryption of private content (DONE)
- author/person organization (DONE)
- personal notes with file attachments for each user (DONE)

Technical details - Package Structure:
net.geoadel.bibcite - main package containing the calling class that starts the register / login GUI
cryptography - contains the implementation of jasypt, these methods are called by the database objects which take care of calling the appropriate encryption / decryption methods for their fields
datafields - some static datafields (like languages, bibliography types, preferences [should later be changed to user preferences])
database - contains the bridge to db4o so that objects can be stored, retrieved and deleted (huge class, may benefit from refactoring in storage, retrieval and delete classes)
databaseObjects - contains all the object types to be stored in the database - all need to extend dbObject as the root object containing all absolutely necessary fields
docType - contains some DocumentTypes for NumberDocuments (like restricting to 4 digits for a year-field, etc.)
Events - for now only used by JTree-events for the main selection JTreeView (not sure, if other events should be transfered here as well)
FileFilters - some file filters for JFileChooser (images, word documents, bibtex files, etc..)
GUI - all the graphical User interfaces
Images - some images I created for the project
ImportExport - import and export java files; for now only bibtex standard is supported [plus an additional custom field containing citations which can be imported, too)
Tools - some general tools for file and image manipulation plus a BaseN class that helps creating unique handles for the bibliography key

Technical details - Libraries:
- Database is the open source GPL3 variant of db4o, an object oriented database (www.db4o.com)
- String field encryption is provided by jasypt (Apache 2 License) jasypt.org [which needs the apache commons library lang]

Other details:
My first real life java project, not a professional programmer, entirely self learned by reading books and web pages. So if some important standards are not met, I apologize in advance. I tried my best to document this project as well as possible so that I will understand the structure in time to come still and others can dive into it quickly for learning or contribution.
