The name was originally an acronym for "Poor Obfuscation Implementation", referring humorously to the fact that the file formats seemed to be deliberately obfuscated, but poorly, since they were successfully reverse-engineered.

The Apache Jakarta POI project contains the following subcomponents:

  • POIFS (Poor Obfuscation Implementation File System) - This component reads and writes Microsoft's OLE 2 Compound Documentation format. Since all Microsoft Office files are OLE 2 files, this component is the basic building block of all the other POI elements. POIFS can therefore be used to read a wider variety of files, beyond those whose explicit decoders are already written in POI.
  • HSSF (Horrible SpreadSheet Format) - reads and writes Microsoft Excel (XLS) format files. It can read files written by Excel 97 onwards. This file format is known as the BIFF 8 format.
  • HPSF (Horrible Property Set Format) - reads "Document Summary" information from Microsoft Office files. This is essentially the information that one can see by using the File|Properties menu item within an Office application.
  • HWPF (Horrible Word Processor Format) - aims to read and write Microsoft Word 97 (DOC) format files. This component is in initial stages of development.
  • HSLF (Horrible Slide Layout Format) - is a pure Java implementation for Microsoft Powerpoint files. This provides a limited ability to read and edit presentations and it is presently in the initial stages of development.

What Is Poi Anyway? (342 words)
Poi is made from the popular taro plant: the 14th most cultivated crop on earth.
The bowl of poi was considered so important and sacred a part of daily Hawaiian life that whenever a bowl of poi was uncovered at the family dinner table, it was believed that the spirit of Haloa, the ancestor of the Hawaiian people, was present.
Poi is also a common term for a variety of other things, including fire poi for dancing, Jakarta POI for Apache, and P.O.I.
