|
|
<p>Microsoft applications like "Word", "Excel" or "Powerpoint" let the user
|
|
describe his document by properties like "title", "category" and so on. The
|
|
application itself adds further information: last author, creation date
|
|
etc. These document properties are stored in so-called <strong>property set
|
|
streams</strong>. A property set stream is a separate document within a
|
|
<link href="../poifs/index.html">POI filesystem</link>. We'll call property
|
|
set streams mostly just "property sets". HPSF is POI's pure-Java
|
|
implementation to read and write property sets.</p>
|
|
|
|
<p>The <link href="how-to.html">HPSF HOWTO</link> describes what a Java
|
|
application should do to read a property set using HPSF, how to retrieve
|
|
the information it needs, and how to write properties into the
|
|
document.</p>
|
|
|
|
<p>HPSF supports OLE2 property set streams in general, and is not limited to
|
|
the special case of document properties in the Microsoft Office files
|
|
mentioned above. The <link href="internals.html">HPSF description</link>
|
|
describes the internal structure of property set streams. A separate
|
|
document explains the internal of <link href="thumbnails.html">thumbnail
|
|
images</link>.</p>
