PDFBox is aiming to support PDF files inline with the ISO-32000 (PDF) Specification ISO Site Adobe Version
The following table outlines the status of the implementation of various part of the PDF specification as well as the reference to the java packages and classes implementing these.
The table below is work in progress as we enhance our documentation. If you find errors within please report the [issue](https://issues.apache.org/jira/browse/pdfbox).
For easier reading the package names are abbreviated. o.a.p is used instead of org.apache.pdfbox.
