PDF and Open Data Project Update

Hello everyone,

Good evening! It's been a while since I've last given an update to the 
status of the PDFData project, and a lot has happened in the interim. If 
you haven't looked at the project before, you can find an introduction 
and more info here <https://github.com/Aiybe/PDFData/blob/master/README.md>.

And here's a list of major current features and where you can find them:

  * The PDFData Java library
    <https://github.com/Aiybe/PDFData/tree/master/od-reader>, written
    with Apache PDFBox and Adobe's XMP library. Supports reading and
    writing data tables from and to PDF files with a variety of storage
    methods (attachment, annotation, form, etc.)
  * The command line interface
    <https://github.com/Aiybe/PDFData/tree/master/od-frontend> (aka
    frontend), which wraps the Java library in a nice interface with two
    essential functions: adding data, given a PDF file and one or more
    data file(s); and extracting data, given a PDF file and a
    destination. It's a fairly thin wrapper around the library, and more
    attention on the user-friendliness end has gone to the web service.
  * The aforementioned web service
    <https://github.com/Aiybe/PDFData/tree/master/od-web> (try it online
    here <https://pdf.abe.im/>), which provides a much higher-level
    wrapper interface around the library's functionality. It supports
    all the same operations, but has a nice editor interface and visual
    feedback understandable by end-users. It's not yet finalized, but a
    working demo is online and available for use.
  * A variety of pieces of example data
    <https://github.com/Aiybe/PDFData/tree/master/examples>, with visual
    PDFs with real-world data tables stored in them. These can be played
    with in the web or command line interfaces and provide an example of
    (some of) the tool's capabilities.
