ANN: C# XMP Toolkit

Question

Adobe provides the XMP Toolkit that gives developers the ability to easily extract, modify and inject XMP into a multitude of file formats. Unfortunately for .NET developers, it is only available for C++ and Java.
This is where the
C# XMP Toolkit fits in. It includes all the functionality from the XMP Toolkit and extends it with great new features.
Wraps XMPFiles, allowing easy extraction and injection of XMP.
Wraps XMPCore (XMPMeta, XMPIterator and XMPUtils), allowing easy editing of XMP.
Extends with new schema classes, for even easier editing of XMP.
Can be used by any .NET 2.0 application.
Freeware!

Answer 1

Version 0.1.2 is now available with updates and additions to the schemas.
Available schemas in this release:
DublinCore
Iptc
Photoshop
XmpBasic (except for Thumbnail property)
XmpRights
The following code snippet shows how easy it is to add XMP support to your application:
// Update Title, Keywords and Rating.
using (Xmp xmp = Xmp.FromFile("sample.jpg", XmpFileMode.ReadWrite))
    DublinCore dc = new DublinCore(xmp);
    dc.Title["x-default"] = "A sample image";
    dc.Subject.Clear();
    dc.Subject.Add("a");
    dc.Subject.Add("sample");
    dc.Subject.Add("image");
    XmpBasic basic = new XmpBasic(xmp);
    basic.Rating = 5;
    basic.MetadataDate = DateTime.Now;
    // See what's about to be stored.
    string xmpDump = xmp.Dump();
    xmp.Save();
