How to store Metadata in the PowerPoint Presentation (2000, XP, 2003)

[msnews.microsoft.com]

I'm trying to find some way to store Metadata inside the PowerPoint
presentation. I am looking solution for PowerPoint 2000, XP, 2003 versions.
The only way I found is to save it in Custom Properties, but it have size
limitation to 255 characters, so it not useful for me. In Word document I
found something calls Variable, which solves me the problem. Is exist
similar solution for PPT? It can be different solution for different
PowerPoint versions.

I'm programming in C# with Office Object Model

P.S I'm looking for same solution in Excel Sheets too.

Thanks.

Take a look at the Tags object. It can hold a lot of information. They are
available at Presentation, Slide and Shape levels.
