< p align = "justify" > A Microsoft Office document is internally organized like a filesystem
with directory and files. Microsoft calls these files
< em > streams< / em > . A document can have properties attached to it,
like author, title, number of words etc. These metadata are not stored in
the main stream of, say, a Word document, but instead in a dedicated
stream with a special format. Usually this stream's name is
< code > \005SummaryInformation< / code > , where < code > \005< / code > represents
the character with a decimal value of 5.< / p >
< p align = "justify" > A single piece of information in the stream is called a
< em > property< / em > , for example the document title. Each property
has an integral < em > ID< / em > (e.g. 2 for title), a
< em > type< / em > (telling that the title is a string of bytes) and a
< em > value< / em > (what this is should be obvious). A stream
containing properties is called a
< em > property set stream< / em > .< / p >
< p align = "justify" > This document describes the internal structure of a property set stream,
i.e. the < em > Horrible Property Set Format (HDF)< / em > . It does not
describe how a Microsoft Office document is organized internally and how

to retrieve a stream from it. See the < a href = "../poifs/index.html" > POIFS documentation< / a > for that kind of
stuff.< / p >

< p align = "justify" > The Horrible Property Set Format is not only used in the Summary
Information stream in the top-level document of a Microsoft Office
document. Often there is also a property set stream named
< code > \005DocumentSummaryInformation< / code > with additional properties.
Embedded documents may have their own property set streams. You cannot
tell by a stream's name whether it is a property set stream or not.
Instead you have to open the stream and look at its bytes.< / p >

< p align = "justify" > Before delving into the details of the property set stream format we
have to have a short look at data types. Integral values are stored in the
so-called < em > little endian< / em > format. In this format the bytes
that make out an integral value are stored in the "wrong" order. For
example, the decimal value 4660 is 0x1234 in the hexadecimal notation. If
you think this should be represented by a byte 0x12 followed by another
byte 0x34, you are right. This is called the < em > big endian< / em >
format. In the little endian format, however, this order is reversed and
the low-value byte comes first: 0x3412.

Microsoft claims that this is a "reserved" field, but it seems to tell
how many sections (see below) are following in the stream. This would
really make sense because otherwise you could not know where and how

< p align = "justify" > If you want to know a property ID's meaning, it is not sufficient to

its category. Due to Microsoft's infinite wisdom the section format ID is
not part of the section. Thus if you have only a section without the

do not know what they mean.< / p >
< p align = "justify" > So each section format ID has its own name space of property IDs.
Microsoft defined some "well-known" property IDs for the Summary
Information and the Document Summary Information streams. You can extend
them by your own additional IDs. This will be described below.< / p >

with less overhead, but people (including software developers) tend to be
better in remembering symbolic constants than remembering numbers.< / p >
