No it does not currently support it but will soon support it, the work is being carried out for its support and beta release is expected to come out in this month.
PowerPoint file format does not have any version field, so you cannot specify the version of ppt file. But if you want to save version info in some shape object by yourself, you can do so both in PowerPoint and with Aspose.Slides.
What is the purpose of SmartTags in Aspose.Cells, perhaps then I could tell you if Aspose.Slides has such or similar functionality.
Thanks for your response. #3 would be very usefull to automatically fill a chart's datasheet. Our goal is to have a PowerPoint "designer" template that is updated with very little custom coding. The values would be replaced in the datasheet similar to the way it works in Aspose.Cells.
I am still confused about the purpose of smart tags. But you can add excel charts in your ppt files with Aspose.Slides
Excel charts are added as OLE objects in slides. You can read OLE chart back later and edit them with Aspose.Cells and then again embed them as OLE object.
For example, in this thread, you will find the working code and project that reads the OLE chart object from ppt file, changes some of its data and then reinsert it.
