Read and edit document properties
Overview
Work with built-in presentation properties such as title, subject, author, keywords and category. These values help applications organize documents or prepare generated reports with consistent metadata. Some properties are managed by the writer or require the document-information workflow.
Usage example (C#)
Install Aspose.Slides for .NET before running this standalone example. Set nonpersonal built-in metadata on a new deck. The values are stored in source.pptx and can be read again after opening it.
using System;
using Aspose.Slides;
using Aspose.Slides.Export;
using var presentation = new Presentation();
var shape = presentation.Slides[0].Shapes.AddAutoShape(ShapeType.Rectangle, 40, 40, 500, 140);
shape.AddTextFrame("Sample slide");
presentation.DocumentProperties.Title = "Demo report";
presentation.DocumentProperties.Author = "Example team";
presentation.Save("source.pptx", SaveFormat.Pptx);
FAQ
Where should I store an application-specific field?
Use a custom document property when the value does not correspond to one of the built-in fields.
Can I read properties without opening every slide?
Yes. Use the presentation-information workflow to read document properties without loading the complete slide model.
Which built-in properties should I update when generating a new deck?
Set fields relevant to the document, such as title, subject, author and keywords. Avoid carrying over stale metadata from a template.
